Watch G-Shock GMA-S140M-1AER

The Watch

The Casio G-Shock lineup knows how to stay on-trend - and this new GMA-S140M-1AER proves it. This sports watch is made for adventurers. Its black resin case, measuring 45.9 mm in diameter and 15.8 mm thick, is engineered to take a beating thanks to its G-Shock protection - a system renowned for its exceptional toughness. The screw-down caseback and mineral crystal shield the dial from everyday wear. Around the bezel, 4 pushers give you access to all the watch's functions, with their roles - "adjust", "reset", "start", and "mode" - engraved directly on the bezel. The black resin bezel sports a rugged, sporty relief and proudly displays the G-Shock protection badge in gold lettering. The case is also built to resist magnetic fields. And with 20 ATM water resistance, you're ready to explore the deep.

The Dial

This black-and-gold multifunction dial delivers a boldly sporty aesthetic, combining analog display for hours and minutes with sub-dials and a digital display. Hours and minutes are tracked by two skeleton gold arrow-shaped hands, both pointing to hour indices marked with gold rivets - punctuating a crisp white minute track. Three sub-dials display the watch's various functions, fully configurable to your preferences.

Water Resistance

With 200-meter water resistance - 20 ATM for those who prefer the elegant precision of watchmaking language - this watch is built for shallow-water diving. It handles showers, baths, open-water swimming, and recreational freediving without breaking a sweat. For professional scuba diving, however, our Ocarat watch team has handpicked 30 ATM models available in our catalog with a quick search on the site. One last word of advice: keep those pushers and crown dry during any water activity!
