Vibrant Yellow Dial Design

The Casio G-Shock GMA-S2100NC-4A features a striking yellow dial inspired by nature's bold colours. Its carbon composite case and bio-based resin strap create a lightweight yet durable sports watch. Designed for women, it combines analog and digital displays with index markers for clear time reading. The 200-meter water resistance suits swimming and surface water activities.

Shock Resistance and Quartz Reliability

The watch delivers G-Shock signature shock resistance for tough environments. Quartz movement ensures accurate timekeeping without winding. Mineral crystal protects the dial from everyday scratches. The fixed bezel and buckle clasp maintain secure fit during active use.

Month Day Date Display Adds Utility

The analog-digital display includes month, day and date functions for practical daily use. Bio-based resin strap material reduces environmental impact while maintaining comfort. Carbon composite construction keeps the 42.90 mm case thin and light. No additional software or accessories are bundled beyond the watch itself.

Questions about this item

How do I set the time and date on the analog-digital display?

Pull the crown to the first click for digital settings and second click for analog hands; the month, day and date window updates automatically once the digital time is set.

What part will need replacing first with daily wear?

The quartz battery cell will require replacement before the carbon composite case or mineral crystal show any degradation.

At what depth does the 200 m water-resistance rating reach its practical limit during continuous swimming?

The 200 m rating covers surface swimming and snorkelling; it is not certified for scuba diving or prolonged high-pressure submersion.
