Head-To-Head: Solar Technologies Employed by Four Major Brands; Tissot, Seiko, Citizen and Casio

In this particular article, I wanted to do a head-to-head comparison between the various solar technologies employed by four major brands: Tissot, Seiko, Citizen and Casio. The comparison will be based on the detailed reviews of four watches in the collection that are tabulated below: 

 

Tissot T‑Touch	Seiko Prospex Alpinist
Citizen Promaster Tough	Casio G‑Shock MOVE

 

Citizen Promaster Tough Super Titaniun Eco-Drive Green BN0241-59W (similar to BN0241-59H) - The Ultimate Universal Watch and a Good Buy, A Review (plus Video)

The Citizen Promaster is the series of watches from the brand designed for sports and the outdoors. Under this series there is a sub-series that has the designation of "Tough" which has the capacity to absorb even more rough usage. I already have in the collection the the Citizen Eco-Drive Promaster Tough Black Dial Bracelet Watch BN0211-50E and the Citizen Eco-Drive Promaster Tough Chronograph Stainless Steel Watch CA0720-54H. Today, I was able to add another member of the 'Tough' family into the collection; the Citizen Promaster Tough Super Titaniun Eco-Drive Green BN0241-59W.

I must say that this new model is a true titanium watch. Although the previous two are also deemed to be made out of 'Super Titanium', in truth, the base material is stainless steel with a thin covering of titanium alloy. Hence, their weight does not reflect a watch that is titanium based.

I got this watch from my trusty dealer, Aiman. Through his sources, he was able to not only procure one from the brand but also offered it to me with a good discount.

Seiko Prospex SFK003J1 Sea Sumo Solar GMT Green (similar to SFK001J1) - Additional Benefit of Solar and GMT, A Review (plus Video)

After launching a number of watches with just minor changes from previous offerings, earlier this year Seiko presented a new refreshing watch with a number of firsts. Based on the common "Sumo" design, these new SFK series uses a new movement that is both solar-powered and features a true GMT (i.e. local jumping hour) function.

As usual, there wasn't any fanfare for the launch. The market only started to noticed when bloggers and watch journalists started to write about it. To be honest, I only found out about it mid-February 2023. Even then, the Seiko website for the Malaysia region does not list the watch. Nevertheless, the global Seiko website has the watch listed. Meanwhile, the watch is now available at all the dealers in Malaysia. 

I already have the SBDC003 (the first generation Sumo) and the SPB103J1 (the third generation Sumo). To be honest I am not sure whether we can quantify the SFK003J1 as the fourth generation Sumo. Despite it having similar shape, dimension and concept (diver watch), the use of a different type of movement and having an additional GMT function may put this model in a class of its own.

Citizen Promaster Marine BN0220-16E Eco-Drive Diver Super Titanium 200 meters (similar to BN0227-09L & BN0228-06W) - A Unique Designed Beater Watch, A Review (plus Video)

In March 2021, Citizen announced a launch of three new set Eco-Drive powered marine models under the Promaster line. These 200 meter dive watches have design features similar to the legendary Citizen 1,300 meter Professional Diver watch of 1982; a watch with the deepest depth rating at that time. 

Honestly, I was intrigued by the shape of the casing. The lug free design and the four very distinctive bezel guards gives the watch a visual perception of toughness as well as uniqueness. Despite the bulk, the weight is deceivingly light due to the use to titanium which I am fond of. 

There are three models to choose from.  I decided on the BN0220-16E (BN0220 for short) as this model closely resembles the 1982 icon. Although this model is available from a local vendor, I decided to go through my favourite Japanese vendor, SeiyaJapan. 

After taking into consideration the importation fees etc., the watch still turned out to be cheaper than getting it from a local vendor.

I did not have to wait long. The courier was very efficient, settling all the import taxes quickly and delivering the watch to me within 72 hours after making the order.

Casio G-Shock G-SQUAD MOVE GBD-H1000-1A7 - Good First Attempt, A Review (plus Video)

Casio has done it again. The Casio G-Shock G-Squad Move GBD-H1000-1A7 is the next step in intelligent watches. Unlike the ubiquitous smartwatches by Apple, Samsung and many more, the Casio G-Shock G-Squad Move GBD-H1000-1A7 (or the GBD-H1000 for short) remains a watch as it core with additional functionalities to increase its capabilities.

Prior to this model, Casio launched the Casio Pro-Trek WSD-F series in 2016, designed for the great outdoors. This series has in its core the Google Wear OS which makes it a mini-computer for the wrist. Charging the watch was via a magnetic USB charging cable. A load of applications can be downloaded for all kinds of activities such as hiking, fishing and tracking. A touch screen makes it easy to manipulate and control the vast number of applications that can be uploaded. This particular model fits perfectly with the definition of a smartwatch.

In 2018, Casio launched the G-Shock Rangeman GPRB1000 series. This is basically a high-end hardcore G-Shock plus additional sensors such as the Bluetooth and GPS. Casio has taken a different approach on the GPRB1000 series compared to the Protrek WSD series. For the new generation Rangeman, Casio kept the 'watch' as the core instead of creating a 'smart watch'. This factor alone resonates strongly with fans. Casio also introduced a dual power charging system: the traditional solar photovoltaic cell as well as a wireless USB charging cradle.

Citizen Eco-Drive Promaster Tough Chronograph Stainless Steel and Titanium Watch CA0720-54H - From Citizen's School of Hard Knocks, A Review (plus Video)

I starting to focus more on Citizen designed watches in the last year or so. My previous biasness against non-mechanical timepieces shielded me from exploring this branch of the horological tree. After braking through the 'quartz' barrier I realised that there are a lot of incredible technologies and applications that can be found in this realm. My paranoia of serviceability as well as the possible deterioration of unique components appear unfounded as a number of quartz timepiece since the early era of the quartz timeline remain in operation without a care in the world.

Earlier this year I purchase the Citizen BN0211-50E Promaster Tough. I was very impressed with the build quality and its capabilities. When I noted that Citizen also came up with a chronograph model under the Tough series, I decided to get one.

There are two models under this sub-group. A bracelet version and a strap version. I decided on the bracelet version with reference CA0720-54H as I am intrigue with the bracelet design.For more information about the series and history, please refer to the special section at the end of this review.

Seiko Prospex Ana-Digi Solar Dive Watch SNJ025 or SBEQ001 "Arnie" (similar to SNJ027 or SBEQ003) - I'm Back, A Review (plus Video)

In the long annals of Seiko, there are a number of its watch designs that have reached cult status. Generally from the professional series, these watches acquired fame through their capabilities and endorsement by famous adventurers and sportsperson. However, there is one model that has been made famous by an actor, Mr Arnold Schwarzenegger. In 1985, he wore the Seiko H558-5009 in the movie Commando.

The Seiko H558-5009 was launched in 1982 and is the first Ana-Digi dive watch that has a digital alarm chronograph with an analog time display.

I idolised Arnold Schwarzenegger when I first saw him act in the first Terminator movie in 1984. When he acted in Commando, I went to see it at the theater. Then, I wasn't a WIS but I could appreciate the 'macho' H558-5009 as the watch of choice for a commando. Forward 35 years since its launch, Seiko has reintroduce the old Ana-digi (with some modern features) into the SNJ025 (or SBEQ001).

When launched, the Seiko H558-5009 recorded a number of firsts. Through the power of the cinema and Hollywood, it created the genre of the professional "action" watches. The new "Arnie" SNJ025 is a fairly close remake of the iconic H558-5009.

Seiko Prospex Fieldmaster LOWERCASE Special Edition Reference SBDJ029 (similar to SBDJ027 & SBDJ028) - The Perfect Tuna for the Masses, A Review (plus Video)

Seiko’s Prospex watches is subdivided into Sea, Land, Sky and Run. Although most would be familiar with the dive watches from the Sea collection, the Land collection is also interesting. In my collection is the Seiko Prospex Fieldmaster SBDC011 (click here for more). It has been given the nickname "Field Tuna" by Seiko fans. It is an automatic watch that features a compass bezel and a shroud similar to that on Seiko's Tuna divers.

Since the introduction of the SBDC011 under the Fieldmaster sub-line in 2010, nothing else of substance was launched by Seiko to carry on the namesake. In 2017, Seiko surprised us with new Prospex Fieldmaster LOWERCASE watches which is similar to past models yet different at the same time.

Made in collaboration with the Japanese design consultants LOWERCASE, Seiko is able to bring something fresh and exciting to its design styling. Lead by Mr. Yuki Kajiwara, creative director of LOWERCASE, the Fieldmaster has been given a radical change in the design department.

Casio G-Shock Full Metal 5000 GMWB5000GD-1ER Black (Similar to GMWB5000V-1ER, GMWB5000-1ER, GMWB5000G-2ER, GMWB5000G-1ER, GMWB5000D-1ER, GMWB5000D-1ER, GMWB5000GD-9ER and GD5000-9JR) - A Must Have, A Review (plus Video)

Since 1983 or over the last 36 years, G-Shock series by Casio has become a cult classic, a must have piece for any serious collector. Casio was lucky to have an engineer by the name of Kikuo Ibe who wanted to create and make the most durable and reliable watch on Earth.

With the launch of the first G-Shock in 1983, the DW-5000C, a number of key innovations were introduced such as keeping the timekeeping module suspended inside the casing with only a few points of contact to reduce shock transmission, capable of withstanding 200 meters of water pressure and could withstand falls of up to 10 meters onto a concrete floor. Since then, the G-Shock has evolved in terms of design and technology. Solar power, Bluetooth connectivity, various sensors as well as GPS have all made it into at least one of the many G-Shock models released over the years. Different materials such as stainless steel and titanium as well as different display styles such as analogue or a mixture of analog and digital have been used to make the series more functional in any situation. No longer would you just find a plain black rectangle shape G-Shock, the range has expended to all shapes, sizes and colours.

Head-To-Head: Seiko Prospex Alpinist Solar Titanium Multi-Sensor SBEB013 versus Casio Protrek Adventure Titanium Triple Sensor Ver. 3 PRW 3000 T7

ABC (Altimeter, Barometer & Compass) watches are the ultimate adventurers' timepiece. In the intervening period between pure mechanical and satellite linking watches, Casio led the way in innovation as well as some excellent examples especially under the Protrek series. Unknown to many, Seiko too has some interesting examples in this genre. This review shall compare Seiko Prospex Alpinist Solar Titanium Multi-Sensor SBEB013 (left of the photo below) against Casio Protrek Adventure Titanium Triple Sensor Ver. 3 PRW 3000 T7 (right of the photo below). In the spirit of transparency, I do own both models and hopefully I can provide an unbiased view in this short report.

Citizen BN0211-50E Promaster Tough Eco-Drive Black Dial Bracelet Watch - Simplicity Is Its Beauty, A Review (plus Video)

Any watch collector will have something to say about quartz watches. All would say that accuracy for quartz powered watches surpasses mechanical timepieces. Unfortunately, a lot of them also will shy away from acquiring a quartz watch due to the prevailing negative perception vis-a-vis a mechanical timepiece. Although I officially don't have such a bias view against quartz watches, the watches I acquire over the years appears to show a high degree of leaning towards mechanical timepieces. After looking at the facts and some soul searching, I came to the conclusion that my historical acquisition trail has been influenced by reviews and comments from other watch collectors.

I realised that my worldview is a reflection of the collective wants of all the watch collectors that are sharing their dreams about this hobby online. Unfortunately, this is not what I want in the hobby. For me, it is all about the design, technology and a watch's position on the evolutionary tree of watches. In the last year or so, I have started to become more inclusive and started to look further into the quartz world.

Citizen Promaster Eco-Drive Professional Diver 1000M Titanium BN7020-09E Solarzilla - The Ultimate Tool Watch, A Review (plus Video)

In my collection I have the 2002-introduced Promaster 1000m (Reference NH6931/NH6930) nicknamed the “Autozilla”. In 2017, when I heard that Citizen was pulling all the stops to come out with something spectacular for Baselworld 2107, I was curious to see the great reveal.

Citizen did not disappoint. The Citizen Promaster Eco-Drive Professional Diver 1000m (Reference BN7020-09E) is the world’s first solar-powered saturation capable diving watch. It is also Citizen’s second 1,000 meter diver. This watch is one of the few watches that can be define as an extreme dive watch. It is capable of exceptional depth and not suited for formal wear. It has been given the nickname “Solarzilla”.

The Solarzilla follows the design philosophy of its predecessor, the Autozilla. Slightly larger than the Autozilla, the Solarzilla is different in a few aspects. First, it is an Eco-Drive instead of automatic. Second, the new diver comes with an additional locking system that has a visual indication to show when the timing bezel is unlocked. Third, the addition of a power reserve reserve indicator.

CITIZEN Promaster TSUNO Chronograph Racer Eco-Drive Limited Edition 100th Anniversary Model AV0077-82E - Bullhead Fame, A Review (plus Video)

The year 2018 marks Citizen Watch Company's 100th year of operation. To commemorate this key milestone, the Company released a series of unique, vintage-inspired bullhead chronograph called the Tsuno Chronograph Racer, at Baselworld 2018 watch fair. The inspiration behind the series was the 1973 Challenge Timer Tsuno Chrono (or “horned chronograph” in Japanese). For more about the series, please refer to a special dedicated section at the end of this review.

What caught my attention was a special 100th Anniversary Model, the AV0077-82E which was not part of the original quartet launched during Baselworld 2018 back in March 2018. This special limited edition is an all black PVD version with matching bracelet. To be honest, I would have gone for the blue dial version but considering the significance of the milestone it honours, I decided on the AV0077-82E.

I found one on SeiyaJapan for USD748.00 or RM3,216.24 (at the time of purchase). Unfortunately, the package was subjected to local taxes which added another RM175.45 (inclusive of RM19.10 administrative fees) to the total.

SEIKO Prospex Fieldmaster LOWERCASE SBEP001 "Digi Tuna" (similar to SBEP003, SBEP005, SBEP007 & SBEP009) - A Good Start by Seiko to Make a New Niche for Itself, A Review (plus Video)

Seiko is synonymous with the tuna-styled dive watches. It has become a genre on itself and a lot of people (especially professional divers) can vouch for their reliability and effectiveness to handle the extreme of situations. There have never been a fully digital Tuna before but this year, Seiko decided to spring five models under the new SBEP nomenclature.

Made in collaboration with the Japanese design consultants LOWERCASE, Seiko is able to bring something fresh and exciting to an otherwise  bland tuna styling that have not gone through much changes for decades. Lead by Mr. Yuki Kajiwara, creative director of LOWERCASE, the SBEP series amalgamate two important considerations by professional users - damage proof construction (the Tuna casing) and clear visual (digital display). This is not a breakthrough in concept though. There are other brands that already fulfilled this market space, for example Casio Protrek Frogman, but for Seikonstas, this is the first for Seiko.

The SBEP001 is also classified as a Fieldmaster. This nomenclature signifies the watch has been geared specifically for land explorers and adventurers. The ability to withstand 200 meters of water pressure also points to its flexibility to be used for recreational diving as well.

Since this is the first of the SBEP series, I decided to get the SBEP001 to grace the collection.

Casio G-Shock GW-M5610BC-1JF JDM Multi Band 6 with Bracelet - A Cornerstone for Any Collector, A Review (plus Video)

Casio produces a number of G-Shock watches only for sale to the Japanese domestic market (JDM). This list of JDM G-Shocks focuses on the 5000-series such as the common DW-5600 and the GW-M5610 models.

I currently have only one G-Shock in the collection (although I listed two on this blog, the G5600-1DR is technically my son's). That is the extra-large GX-56BB-1DR which has some drawbacks due primarily to its size. Although it is a serious tool watch, it does not have the flexibility like its smaller brother, the 5600 series. Its brute bulk is its call to fame.

I need to get a 5600 series model into the collection to experience the additional flexibility of the much smaller and practical classic G-Shock. After doing my research, I decided to get one with a composite bracelet instead of the traditional resin band (like my son's). This particular model I chose has the same style of display like the big brother i.e. a reverse display - white display with black background.

Seiko Prospex Alpinist Solar Titanium Multi-Sensor SBEB013 (Similar to SBEB015, SBEB017, SBEB019, SBEB035 & SBEB037) – A Good Start Against Established Competitors, A Review (plus Video)

The Seiko Prospex Alpinist SBEB013 is my first solar, digital display and ABC (Altimeter, Barometer & Compass) watch from the Seiko family. It is also the third ABC (Altimeter, Barometer & Compass) multi-sensor watch in my collection. I already have the Casio Protrek as well as the Tissot T-Touch. It would be interesting to note the differences in functionality as well as capabilities of the various makes. I will make such a comparison in a special box section later in this review.

It is difficult to get an example of this watch in Kuala Lumpur as Seiko does not officially offer this model here in Malaysia. Through the internet, via Amazon, I was able to source one from a merchant operating out of Japan. Within a week, the package was on my table.

The Packaging

The SBEB013 comes with a quality double cardboard box package. The outer box uses a thinner cardboard material painted in black with the brand logo as well as the Prospex logo on the top of the box in silver. The dimension of the outer box is 12 cm by 9 cm by 8 cm. Inside this box contains the main watch box as well as the manual, warranty and a special instruction booklet on how to resize the bracelet. Included also is a tool for the bracelet resizing. This is a first time I’ve seen Seiko give a resizing tool as part of the presentation package.

Casio G-Shock Black Out Basic Series GX-56BB-1DR – A Brute with Limited Flexibility, A Review (plus Video)

The Casio G-Shock series have been around since 1983 and have a very strong cult following due to its ability to withstand battering. Despite being a watch collector that tends to collect watches with significant contribution to the world of horology, I have yet gotten a G-Shock in collection thus far. However, today a new chapter has dawned and the collection has a new member in the form of the Casio G-Shock Black Out Basic Series GX-56BB-1DR.

The GX series are typically called the “King of G-Shock" models. These are the biggest G-Shocks ever produced by Casio. The company launched the first back in 2010. It has the classic 5600 G-Shock design but in a size that is close to twice the size. The over-sized design is its call to fame. Unfortunately, for some people, the size could be a bit overwhelming.

I got the watch from the Watch Style of Mid Valley Megamall. The MSRP was RM809 (with GST). I was able to get it for RM680. Although I believe I could get it cheaper elsewhere, I still decided to get it from this brick and mortar shop due to the personal service rendered.

Seiko Astron GPS Solar Dual Time White Dial SBXB047 (SSE047) Titanium with Ceramic Bezel Watch – Excellent timepiece with real world applications, A Review (plus Video)

After the Astron was re-launched back in 2012, I finally got myself an Astron for the collection. The delay in getting one was due to the fear factor I get with new technologies – will they actually work? Moreover, when the first batches of Astrons with the 7X Series Calibers installed were on sale, there were a number of issues highlighted by owners. Predominantly, problems surrounding the power usage and the lack of battery capacity were reported. These feedbacks from consumers prompted Seiko to redesigned the GPS module and come out with the latest 8X Series Calibers which eliminated issues that were brought out.

Before we go straight into the review, it would be good to clear up the reference codes used for this series. The Astron is a Made-In-Japan watch line. However, it is not strictly defined as a JDM (Japanese Domestic Market) as it is sold globally. Nevertheless, in true Japanese manufacturing quirkiness, this series has been earmarked with the “SBXB” code when in Japan while the rest of the World has been allotted the “SSE” code. The numerical part of the overall reference code remains the same. Therefore SBXB047 is in fact the SSE047.

CITIZEN Promaster Eco-Drive AQUALAND Titanium Divers Watch JV0055-51E - It sits well on the wrist and is a very capable little dive computer. With its unique shape, it is an excellent conversation starter, A Review

I have yet to have a dive computer as part of my watch collection. Although there are a number of brands offering such a product, I decided to get the Citizen JV0055-51E as it offers a number of firsts for me. Apart from fulfilling my requirement of having a dive computer wristwatch, it is also uses the Eco-Drive technology which is uniquely Citizen. The use of titanium as the base material for the watch was also a reason behind this choice. Coupled with the unique case design, I was sold to this model.

Sourcing this watch was a major undertaking. The current retail price in Malaysia as listed by www.bodying.my is RM6,170.00. This is a price that I would not be willing to get.

Casio PROTREK Adventure Titanium Triple Sensor Ver. 3 PRW 3000 T7, A Continuation of the Super Tough DNA of a Casio Protrek, yet Capable of Doing More by Virtue of its Smaller Electronics and More Contemporary Design, A Review

It has been a long time since I bought myself a digital watch. The last time it happened was back in August 2009 when I got my Suunto Heart Rate Monitor watch. If I recall, my purpose of buying that watch was to fulfill a need - to track my heart rate as I prepare myself for my first marathon.

In reality, I am not an anti-digital watch-hater that only appreciate mechanical watches. Far from the contrary, I love gadgets and the Casio Protrek series have been on my "must-have" list for a long time. The ability of a watch to locate accurately North has been one of my theme for my watch collection. Currently. I have six watches that could do that (using time and sun). The collage of the collection is provided below.

You will note that all are Seikos. Although I would like to have a watch that could do the same from another brand, the various Casio Protrek models that weree on offer were too big and garish for my liking.
