Casio Mens G-Steel Black Dual Display Strap Watch Gm-2100LXB-1A9ER
This G-Shock combines the brand's robust sportswear heritage with refined design touches. The 44.4mm resin case features a matte-black dial with gold-tone accents on the inset complications and mineral crystal bezel, creating visual contrast without excess. A black ion-plated steel bezel and bio-based resin strap keep the overall aesthetic monochromatic, whilst luminescent hands and vapour-deposited baton markers ensure readability in low light.
The quartz movement delivers world time across 31 zones, a 1/100-second stopwatch, countdown timer, five daily alarms, and full calendar function. Hand-shift technology repositions the hands when accessing the digital display, and a white dual LED backlight enhances visibility in darkness. Water resistant to 200 metres and weighing 72g, the watch sits 11.8mm thick on the wrist. Battery life runs approximately three years between replacements.
