CASIO G-Shock GA-B2100FC-3A Green Dial Solar Watch 200m

Carbon Composite Sports Watch

The GA-B2100FC-3A is a new G-Shock built for daily wear and outdoor activity. Its carbon composite case and resin strap keep weight down while meeting the brand’s shock-resistance standard. A green dial and analog-digital display give clear time reading in changing light. The 200 metre water resistance supports swimming and surface water sports.

45.40 mm Case with Fixed Bezel

The round case measures 45.40 mm thick and uses a fixed bezel that protects the mineral crystal from direct impact. A buckle clasp secures the resin band without tools, so the watch stays put during vigorous movement. Solar charging via the Tough Solar system removes the need for regular battery changes. Bluetooth smartphone link lets the watch sync time and adjust settings through a companion app.

Caliber 5689 Functions

Caliber 5689 drives the analog hands and digital sub-dials, showing month, day and date alongside the primary time. The solar cell feeds the rechargeable cell continuously under normal light, maintaining operation in low-use periods. Smartphone link also enables automatic time-zone updates and alarm management from the phone. No charging cable or proprietary dock is required.
