Casio Edifice EFK100D-7A Automatic (similar to EFK-100CD-1A, EFK-100D-2A, EFK-100D-3A & EFK-100XPB-1A) - The Brand’s First Mechanical Watch, A Review (plus Video)

I finally got my hands on Casio's first automatic timepiece. The EFK100 series in under the Edifice line and it was launched in 2025 with much surprise and jubilation from the watch community. For purist, disappointment, as Casio decide against making their own in-house movement, opting to use Seiko's NH35A instead. For me and the vast majority of watch enthusiasts, the fact that Casio has finally embraced the mechanical movement as part of their repertoire of technologies for their watch designs says a lot. The choice of affordable mechanical watches from established brands are shrinking year-by-year as watchmakers goes up the value chain leaving the cheaper alternatives to alternative brands.

I wanted to get it when it was launched in 2025. Then, my choice was either the green or the blue dial version. However, after seeing them for the first time, it was the white dial that really stands out. The texturing on the dial makes it feel like a Grand Seiko 'Snowflake' but at a fraction of the cost. Unfortunately, that particular white dial has already been allocated to another buyer. After waiting for a number of months, finally, one of the branches of AWG got an allocation and a day later, it was on my wrist!

Casio Edifice EFA-100 - A beater-watch, A Review

This Casio Edifice EFA-100 was bought in 1999 for my wife on the birth of our first child. It has a ana-digital interface with allows you to keep track of two time zones rather easily. An all stainless steel construction with bracelet, it has daily alarm setting and calendar programmed until the year 2039.

Made out of stainless steel, it is 37 mm wide and 47 mm long. It case height is 12.5 mm. the lug width is 18 mm. Total weigh is approximately 148 gm. The larger part of the watch face is allocated to the analogue portion while the digital part of the watch is located in two small windows at the bottom.

The crown to adjust the analogue hands are located at 3 o'clock while the two pushers to adjust the digital part of the watch is located at left side of the casing. 

The dial is protected by mineral glass.

The odd shaped casing do create some problems in the long run. Opening the case-back over the years to replace the batteries requires one to be extremely careful handling the rubber seals. However, as the rubber seal ages, over time, it has to be replaced. However, you may not be able to find spare parts due to the uniqueness of the casing. Despite having a 100 meter water rating, it is best not to chance it.

Overall, a simple watch to have as a daily beater-watch.

Casio EF331SB1AV Edifice Solar - Classic Yet Robust, But More Importantly, Cheap - A Review

This is a watch of many firsts; my first Casio; my first solar powered watch; and, my first square shaped watch. I bought it out of impulse when I walked passed a watch shop having a special sale.

Under the Edifice line, this watch is very basic and does not have the complications that are commonly associated with that line. Instead, it has a day and date function set in two sub-dials at 12 o'clock (date) and at 9 o'clock (day). Another sub-dial at 6 o'clock has a 24 hour indicator.

The dial is clean and indexed.
