The Casio G-Shock GM-2100LXB-1AER reinterprets the signature octagonal 2100 design with the understated styling of the Luxe Black Series. A finely textured matte-black dial reduces glare, while redesigned slim hands, vapour-deposited baton hour markers, and subtle silver accents create depth without disrupting the monochromatic finish. The 44.4mm resin case is framed by a hairline-finished stainless steel bezel with black ion plating and paired with a textured black bio-based resin strap. Measuring just 11.8mm thick, the case is protected by mineral crystal glass. Its quartz movement provides dependable timekeeping alongside world time across 31 time zones, a 1/100-second stopwatch, countdown timer, five daily alarms, and a full automatic calendar. Neobrite details and a double LED Super Illuminator support visibility in darker environments, while the hand-shift function clears the digital display whenever required. Shock-resistant construction, a lightweight 72g build, and water resistance up to 200 metres complete this refined yet characteristically durable G-Shock. • 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
