CASIO G-SHOCK GM-2100YRA-8ADR FINE METALLIC 2100 ANALOG-DIGITAL SILVER RED WATCH

The GM-2100YRA-8ADR is the Fine Metallic edition of the metal-bezel GM-2100 — the GM-2100's signature octagonal stainless steel bezel finished in silver with separate hairline and mirror polishing on different surfaces, paired with a vivid red LCD display and red-and-black accent details. The silver-and-red colour combination gives the watch a futuristic, cyberpunk edge that standard black or earth-tone GM-2100 variants don't have. The stainless steel band loop components, the silver vapor deposition on the underside of the transparent urethane band, and the urethane-film-protected silicone band surface all reinforce the attention to material detail that defines the Fine Metallic series.

Module 5611 powers the GM-2100 platform: analog-digital with two hands (hour, minute) and a day sub-dial, hand shift for unobstructed digital reading, world time across 31 time zones (48 cities), 1/100-second stopwatch with split time, 24-hour countdown timer, five daily alarms, double LED Super Illuminator (separate LEDs for face and digital display), Neobrite lume, and a full auto-calendar to 2099. At 49.3 × 44.4 × 11.8 mm and 84 grams, the GM-2100 is one of the slimmest metal-bezel G-Shocks — the 11.8 mm profile sits flat under a shirt cuff. Shock resistant, 200-metre water resistant. SR726W × 2 batteries, approximately three-year life.

Why You'll Love It

• The octagonal stainless steel bezel is the GM-2100's defining design element — the eight-sided form that earned it its nickname. On the Fine Metallic edition, the bezel is polished with separate hairline and mirror finishes on different surfaces, creating a shifting interplay of matte and reflective textures as light moves across the faceted shape. The silver tone is sophisticated without being flashy — it reads as a refined metal watch, not a flashy sport one.
• The vivid red LCD is the Fine Metallic's signature accent. Against the silver bezel and silver-toned band, the red digital display creates a futuristic contrast — red on silver — that gives the watch a cyberpunk, science-fiction aesthetic. Red and black accent details on the dial complete the colour story. It's a G-Shock designed for nightlife, urban environments, and anyone who treats their watch as a style statement.
• The band construction is unusually detailed for a G-Shock. Tough silicone for comfort and flexibility, with the top surface protected by a urethane film for outstanding abrasion resistance. The underside of the transparent urethane features a silvery vapor deposition finish that blends seamlessly with the metal bezel — even the part of the band that touches your skin has a metallic appearance. The band loop uses stainless steel components rather than standard resin. Every element maintains the silver-metal theme.
• At 11.8 mm thick, the GM-2100 is one of the slimmest metal-bezel G-Shocks available. It slides under a shirt cuff, sits flat on the wrist, and doesn't catch on jacket sleeves. At 84 grams, it's lighter than most metal-bezel G-Shocks — the resin case body keeps the weight down while the stainless steel bezel provides scratch resistance and visual weight.
• Hand shift retracts the analog hands for a clear view of the digital display — world time, stopwatch, timer, and alarm modes are fully readable without hand overlap. The double LED Super Illuminator uses separate LEDs for the analog face and the digital sub-display, lighting each independently.
• 200-metre water resistance and shock resistance. The Fine Metallic styling doesn't compromise on G-Shock toughness — this is rated for swimming, snorkelling, drops, and daily abuse.
