CASIO G-Shock GM-S2100CB-5A watch rose gold dial 200m 40.40mm

Rose gold dial and bio-based resin

The Casio GM-S2100CB-5A is a women's sports watch that pairs a rose gold analog-digital dial with a bio-based resin case and strap. Quartz movement provides reliable timekeeping, while the 200m water resistance and shock-resistant construction suit active daily wear. The 40.40mm case thickness gives a substantial presence on the wrist without excessive bulk.

Check strap fit and display preference

Verify that the resin band with buckle clasp suits your wrist size and closure preference before ordering. The fixed bezel and mineral crystal are integrated into the case, so consider whether the combined analog and digital display meets your readability needs. Ensure the watch's styling aligns with your intended use, from casual to water-based activities.

Upgrades from basic digital or resin models

This model replaces simpler digital-only watches by adding an analog-digital display, rose gold dial accents and bio-based resin materials for a more refined look. The jump is worth it when you want 200m water resistance and shock resistance in a design that transitions from sport to everyday settings. It is not for buyers who need smartwatch connectivity, solar charging or a metal bracelet.
