Seiko Prospex Alpinist GMT Limited Edition SPB409J1 (similar to SPB377J1 & SPB379J1) - A Great Candidate for the ‘Best General Purpose Watch’, A Review (plus Video)

The sub-series Alpinist has been one of my favourites. In the collection, I have the first modern Alpinist, the SARB017, the digital model SBEB013, the modernized SPB117 and a special re-creation, SJE085

For the 110th anniversary of Seiko's first wristwatch, the company launched limited edition timepieces in a number of sub-lines. One of the sub-lines is the Alpinist. This new variant comes with an added twist - a GMT movement while still retaining the DNA that makes the Alpinist famous.

Seiko has been vary prolific in 2023 when it comes to GMT functionality. A number of new models with their new GMT movement was launched throughout the year with a lot of positive feedback. The Alpinist was also given the GMT option.

I decided to get the silver dialed version which is a limited edition design with has a total circulation limit of 3,000 units. I got it from AWG Mid Valley

The Story Behind the 110th Anniversary   

Although the history of Seiko began in 1881, it was only in 1913 did the company produced Japan’s first wristwatch, the Laurel. Below is the watch that started the Seiko brand.

The 1913 Laurel

To commemorate this milestone, Seiko decided to create limited edition timepieces for the
Presage, Prospex, Astron, and 5 Sports lines. On 9 September 2023, Seiko announced the list of limited editions for this important milestone, the 110th anniversary of Seiko's first wristwatch. Three timepieces under the Presage line, two under the Prospex line and one each under the Astron and 5 Sports lines. Below is the list of the timepieces and some of their specifications for reference.

The Series

Under the Alpinist GMT series, there are three models available. These are:
 

SPB377J1

SPB379J1

SPB409J1
Blue sunburst dial
Blue leather strap
Standard production
MSRP RM5,800
Black dial
Black leather strap
Standard production
MSRP RM5,800
Silver sunburst dial
Stainless steel bracelet
Limited Edition 3000 units
MSRP RM7,200

I like the blue but the silver dial version is more flexible with the addition of the standard bracelet in the package.


The Watch

The story of the Alpinist has been covered extensive in this blog (see SARB017,SBEB013SPB117 and SJE085). Suffice to say that the SPB409J1 is the first mechanical GMT to grace the line (there were others before but powered by quartz movements). Made out of stainless steel with super-hard coating, the watch has a diameter of 39.5 mm with a length of 46.4 mm and a thickness of 13.6 mm. The Alpinist DNA is unmistakable, with a well-protected screw-down crown and a secondary crown at 4:00. As an extra, due to the addition of a GMT hand, a fixed bezel with a 24-hour scale is also provided.



The SPB409J1 has a silver-toned brushed dial with blue-coloured hands. The hands are still shaped in a cathedral style. All four hands are coated with LumiBrite and a date complication can be seen via a round aperture located at 4:30. This choice of location for the date aperture is good as it eliminates the need to sacrifice a hour marker. Another positive is that Seiko dispensed the need for a magnifier which can be divisive to a lot of fans.

An important element of the Alpinist, is the inner rotating bezel with a compass scale. Controlled with the secondary crown, the inner bezel is bidirectional. The angled surface of the inner bezel is cream in colour and the markers are printed in black in a combination of lines, numbers and letters except for the letter 'N' which is painted red.

 

There are two sets of scales on the watch. The primary hour scale has a combination of applied Arabic numerals and triangular markers in a golden tone. The secondary scale is a sub-second style with combination of lines as well as LumiBrite dots set in a track at the end of the dial.

There are six lines of texts and logo on the dial. The brand is applied while the Prospex logo is painted on the dial. Both are located in the upper quadrant of the dial. The rest of the texts, such as 'GMT', 'AUTOMATIC 3 DAYS' and '20 BAR' can be clearly seen at the bottom quadrant. Meanwhile, the last and smallest texts with the words 'JAPAN 6R54 -OOAO R 3" can be found near the train-track scale at 6:00.
 
Protecting the dial is a slab of curved sapphire crystal with anti-reflective coating on the inner surface. The crystal is surrounded by a fixed bezel that has that explorer-style 24 hour markings which has been cut into the surface and painted black. On closer inspection, the edge of the crystal is beveled.

The primary crown is a screw-down but minus any symbols. This is a pity. The SARB17 has a nice 'S' on the top of the crown but when Seiko launched the SPB117 it became sterile. A lot of fans commented and complained about this. I though Seiko would acknowledge the requests of fans and bring back a marking on the crown (even the Prospex logo is acceptable) but unfortunately, the brand has decided otherwise. Meanwhile, the secondary crown is similar except for one aspect: the top of the secondary crown has a dimple unlike the primary crown. I suppose this is to give a tactile feel to differentiate between the two.


The curved lugs do not have pass-through lug holes to facilitate ease of strap replacement. It is 20.0 mm wide. The bracelet tapers slightly to 18.00 at the clasp. The signed clasp is a simple push button release with two micro-adjustment points provided. The bridge that joins both sides of the bracelet is machined instead of stamped metal. This enhances the overall quality of the watch.



Do note that as part of the limited edition offering for this watch, an additional brown leather strap with clasp is provided in the packaging.



The screw-down case-back has a display
window made of sapphire. This is the second variant to have a display case-back. Through it, one can see the new Seiko 6R54 automatic GMT movement (this caliber was launched in March 2023). This movement has 24 jewels and operates at 21,600 BPH and delivers 72 hours of power reserve. It also has a magnetic resistance up to 4,800 A/m and has an accuracy precision of between +25 seconds/day to -15 seconds/day.  The 6R54 allows one to set the 24-hour GMT hand independently. This makes the movement an office GMT rather than the more elegant traveler’s GMT. In this case, one should read the local time on a 24-hour scale when traveling.



Despite this watch being part of the 110th Anniversary of Seiko's first wristwatch limited edition offerings, the only notation on this matter was the words 'LIMITED EDITION' printed in black at the center of the display case-back. There is no other information with regards to the unit number of my model relative to the other 3,000 units. Very strange. The reference number for the watch is also generic: 371562, which conforms to the numbering methodology of Seiko i.e. the watch was made in 2023 in the month of July and is the 1,562 lot produced. Does anyone knows why Seiko decided not to number this limited edition piece? If you do, please note it in the comment section below. In any case, I am going to provide a feedback to Seiko to remedy this in future limited edition offerings.

Comparison Between The Various Alpinist In The Collection

As highlighted earlier, before the SPB409J1, I have already collected the SARB017, SBEB013, SPB117 and SJE085. For a more meaningful comparison, I will exclude the SBEB013 as it is a digital quartz timepiece and not strictly comparable the the other Alpinists.

Personally, I cannot appreciate watches with magnifying cyclops on the crystal. When compared to the original Alpinist which is represented by the SJE085J1 and the modern Alpinist represented by the SARB017J1, my money is with the modern interpretation. It has all the hallmarks of a watch fit for a mountaineer. The original Alpinist design is rather generic. Fitting the additional GMT functionality in the SPB409J1 is truly the icing on the cake. 


The Wearing Experience

Having the watch with a sub-40 mm wide casing makes it a comfortable timepiece to wear for long periods of time. To be able to use as intended, the strap should be leather or cloth. For the SPB409J1, Seiko did provide a leather alternative to the bracelet.

Below is a video of the watch on my wrist.

 

I find the watch to be extremely useful. Although the price is rather on the high side (although Seiko may find it justifiable to increase the price-point of their watches due quality improvement and brand franchise, it effectively alienates a good proportion of their current fan base which are cost conscious) I still feel that this watch is value-for-money. As a wearer, the watch can be used is all occasions, may it be formal, up a mountain slope or snorkelling in the sea.

My suggestions for future iterations are as follows:
  • Quick-release lug bars for bracelet & straps
  • Pass-through lug holes for ease of strap replacement 
Final thoughts, the SPB409J1 is a great candidate for the ‘best general purpose watch’ at the moment.
