Refined gold accents distinguish the Casio G-Shock GM-2100LXB-1A9ER from the monochromatic styling of the Luxe Black Series. Its finely textured matte-black dial is designed to absorb light and reduce reflections, while slim luminescent hands and vapour-deposited baton hour markers provide clear definition. Gold-tone details across the inset dials and around the perimeter of the mineral crystal add depth and controlled shine. The 44.4mm resin case measures 11.8mm thick and is framed by a black ion-plated stainless steel bezel, with a black bio-based resin strap completing the design. Powered by a quartz movement with an approximate three-year battery life, this shock-resistant watch includes world time across 31 time zones, a 1/100-second stopwatch, a countdown timer, five daily alarms, and a full automatic calendar. Its hand-shift function moves the hands away from the digital display when required, while a white double LED Super Illuminator provides enhanced visibility in darker conditions. The watch weighs 72g and offers water resistance up to 200 metres. • Powered by the quartz movement • Presented on a black bio-sourced plastic strap with traditional buckle • Mineral crystal glass • 44.4mm case width & 49.3mm case length measuring from lug to lug • 200 metre water resistance
