The Casio Edifice ECB-S100D-1A pairs an analog-digital display with Tough Solar charging, Bluetooth smartphone linking, a sapphire crystal and 100-meter water resistance. Its published specifications make it a feature-rich stainless-steel watch, but Casio labels it an “Old Model,” and the available product information does not establish current stock, present-day pricing or independent wear-test results.
What is the Casio Edifice ECB-S100D-1A?
It is a stainless-steel analog-digital watch with Bluetooth connectivity and solar charging. Casio lists dimensions of 50 × 46 × 9.8 mm and a weight of 137 g, alongside a 100-meter water-resistance rating. The case and bezel are stainless steel, as is the band, which uses a one-touch three-fold clasp. These are substantial specifications to consider when deciding whether the watch’s size and metal construction suit your preferences; they do not establish how it feels on the wrist.
Casio’s international product page identifies the ECB-S100D-1A as an “Old Model.” The page is useful for checking the manufacturer’s specifications, but it does not confirm live inventory or a current selling price.
What features does the ECB-S100D-1A offer?
Display and construction
The watch combines analog hands with a digital display. Its sapphire crystal has an anti-reflective coating. Casio lists double LED illumination for the face and digital display, plus a hand-shift feature that moves the hands clear of digital content. Whether the display is easy to read in your typical lighting or the case is comfortable for you is not established by these specifications.

Solar charging and smartphone linking
Tough Solar charges the watch using light, while Bluetooth linking works with the CASIO WATCHES app. Casio describes app features that include automatic time adjustment and Time & Place logging. The product page also lists approximately 300 world-time cities as an app feature; that is separate from the watch’s own specification of 38 time zones (38 cities plus UTC).
Casio estimates about seven months of operation after a full charge with normal use and no further light exposure. Its estimate rises to about 18 months if the watch is fully charged and then kept in total darkness with power saving enabled. These are manufacturer estimates under the stated conditions, not independent battery testing.

Is the Casio Edifice ECB-S100D-1A worth buying?
On specifications alone, it may suit someone looking for an analog-digital stainless-steel watch with solar charging, app-linked time adjustment, a sapphire crystal and a broad set of practical functions. Its 50 mm case length, 46 mm width and 137 g listed weight are important fit considerations, but the specification sheet cannot tell you whether those dimensions will work comfortably on your wrist.
Availability is a separate question from whether the feature set appeals to you. Since Casio calls this an “Old Model” and gives no confirmed current stock or price in the cited product information, check any listing for the exact ECB-S100D-1A, seller, condition and regional variant before buying. No independent assessment of comfort, legibility, durability or app performance is established here, so specifications should not be mistaken for hands-on findings.
