Edifice Ana-Digi Solar Chronograph

The CASIO Edifice ECB-900GL-1A combines analog hands with a digital display in a stainless-steel case. A leather strap secures the 48.00 mm case with a buckle clasp. Solar charging powers the movement without battery changes. The watch is built for men who want a chronograph that handles daily wear and water exposure to 100m.

Smartphone Link for setup and sync

Bluetooth connectivity links the watch to a companion app on your phone. The link sets the time, manages world-time cities and configures alarms without pressing multiple buttons. It frees the crown and pushers for stopwatch operation. Mineral crystal protects the black dial during the pairing process and everyday knocks.

Solar reserve keeps running in low light

The Tough Solar cell charges under indoor and outdoor light, storing energy for months of darkness. Chronograph timing and daily alarms draw from this reserve without draining a replaceable cell. Water resistance to 100m means swimming and showering do not interrupt the charge cycle. The fixed bezel and screw-down case back maintain the seal under sustained pressure.

Questions about this item

How long will the solar cell keep the watch running once fully charged under daily wear?

The Tough Solar cell stores enough energy to run the chronograph and Bluetooth link for months on a full charge, and normal daylight exposure tops it up continuously.

How much heat does the case generate when the chronograph and smartphone link run all day?

The stainless steel case and mineral crystal stay at skin temperature; the low-draw solar movement produces no noticeable warmth even with continuous chronograph use.

What phone and app are needed before the watch can sync time and alarms?

You need an iOS or Android phone with the free Casio Watches app installed and Bluetooth enabled to pair with the ECB-900GL-1A.
