White Dial Solar Sports Watch

The Casio GA-B2100FC-7A combines a crisp white dial with a hybrid analog-digital display. Tough Solar charging keeps the movement running from ambient light, while Bluetooth smartphone link adds automatic time sync and notification alerts. Shock-resistant resin construction and 200m water resistance suit daily wear and outdoor activity.

Thermals Noise Power Draw

Solar charging eliminates routine battery changes and draws no mains power. The resin case and strap stay comfortable across temperature swings and generate no audible noise. Bluetooth connectivity operates only on demand, keeping standby consumption minimal.

Smartphone Link Benefits

The companion app handles world-time setting, alarm configuration and timer presets without pressing multiple crown sequences. Automatic time correction adjusts for daylight-saving changes when paired. Phone-finder and notification filters reduce the need to check the handset during workouts or meetings.

Questions about this item

How do I charge the solar cell on the GA-B2100FC-7A, and what step do people often miss?

Expose the white dial to bright light; the step many miss is leaving it under a sleeve or in a drawer where the solar panel cannot collect energy.

What part of the GA-B2100FC-7A will need replacement after several years of daily wear?

The internal rechargeable cell that stores solar power will eventually hold less charge and require a watchmaker to swap it.

At what depth does the 200 m water-resistance rating of the GA-B2100FC-7A reach its practical limit during prolonged immersion?

The 200 m rating covers recreational diving; beyond that depth the seals on the 45.40 mm resin case are not guaranteed.
