Casio Edifice Men Connected Solar Watch - Grey | ECB-900MDC-1ADR combines a monochromatic grey ion-plated metal design with advanced motorsport-focused functionality.

Casio Edifice Men Connected Solar Watch - Grey | ECB-900MDC-1ADR delivers the EDIFICE combination of speed, intelligence, and bold styling in a distinctive monochromatic design. Casio applies grey ion plating to both the case and bracelet, creating a sophisticated dark-metal appearance.

The stainless steel case measures 51.5 × 48 × 13.9 mm, while the complete watch weighs approximately 164 g, giving it a substantial full-metal feel on the wrist. The matching stainless steel bracelet uses a convenient one-touch three-fold clasp.

Its analog-digital face is designed with motorsport functionality in mind. A large inset dial positioned around 4 o'clock serves as a speed indicator, displaying average speed when lap times are measured over a preset distance. A tachymeter further reinforces its racing-inspired character.

Integrated Bluetooth Smartphone Link connects the ECB-900MDC-1ADR with the CASIO WATCHES app. Connected functions include automatic time adjustment, easy watch settings, approximately 300 world time cities, stopwatch data transfer, and Phone Finder.

The built-in 1/1000-second stopwatch provides highly precise timing during the first 60 minutes, then measures in 1/10-second increments afterward for a total capacity of up to 24 hours. It supports elapsed and lap timing, stores up to 200 lap records, and can calculate speeds from 0 to 400 units per hour.

The watch also provides World Time across 39 time zones, covering 39 cities plus UTC, with daylight-saving adjustment and Home City / World Time City swapping.

A 24-hour countdown timer, five multi-function alarms, hourly time signal, Hand Shift function, full auto-calendar through 2099, and selectable 12/24-hour time format add extensive everyday functionality.

High-brightness Double LED Super Illuminator lighting illuminates both the analog dial and digital display. The full-auto light function can activate simply by tilting the wrist, improving visibility in dark environments.

The ECB-900MDC-1ADR is powered by Tough Solar. From a full charge, Casio rates operating time at approximately 6 months under normal use without additional light exposure, or up to 19 months with Power Saving enabled.
