CASIO G-SHOCK GMA-S140VA-7A Bio Based White Resin Watch

Purpose & Wearer

The Casio G-SHOCK GMA-S140VA-7A is a quartz sports watch built for women who need a tough everyday timepiece. Its bio-based white resin case and strap keep the weight low while the 200 m water resistance handles swimming and surface water sports. Shock and magnetic resistance protect the movement from daily knocks and electronic fields. The screw-down case back adds extra sealing for durability.

Deciding Specification

The analog-digital display combines traditional hands with a digital readout so you can read the time at a glance and still access precise timing functions. World time covers 29 zones, a 1/1000-second stopwatch and countdown timer handle interval training, and five daily alarms plus an hourly signal keep schedules on track. Neobrite luminous hands and an LED light ensure visibility in darkness.

Build Integration

A 45.90 mm resin case sits flat on the wrist and fastens with a buckle clasp, requiring no special tools or adapters for strap changes. Mineral crystal shields the dial from scratches without adding bulk. The watch runs on a standard quartz movement, so there is no charging cable or battery hatch to manage during regular use. It suits wearers who want a single device for timekeeping, timing and world time without needing a smartphone link.
