CASIO G-SHOCK GM-5600YRA-8DR FINE METALLIC 5600 ORIGIN DIGITAL SILVER RED WATCH

The GM-5600YRA-8DR is the Fine Metallic edition of the metal-bezel 5600 — the most historically significant G-Shock silhouette dressed in the series' silver-and-red colour story. The 5600 is a direct descendant of the DW-5000C, the first G-Shock ever made in 1983 — and the rectangular shape, recessed display, and side-button layout have barely changed in over four decades. The Fine Metallic treatment clads the bezel in polished silver stainless steel with separate hairline and mirror finishes, adds a vivid red LCD, and wraps the band in the same tough silicone with silver vapor deposition underside used across the series. At 76 grams and 12.9 mm thick, it's the lightest and most compact of the four Fine Metallic models.

Module 3525 runs the 5600 platform: LED Super Illuminator with flash alert (LED pulses with the buzzer), 1/100-second stopwatch with split time, 24-hour countdown timer with auto-repeat, multi-function alarm with hourly time signal, full auto-calendar to 2099, and ±15 seconds per month accuracy. Pure digital, no analog hands, no world time — the same intentional simplicity as the GM-6900YRA, with the same five-year battery life on a CR2016. Shock resistant, 200-metre water resistant. The 5600 is the G-Shock for people who want the original shape with metal-bezel elevation — nothing more, nothing less.

Why You'll Love It

• The 5600 is where G-Shock started. The rectangular case, recessed display, and side-button layout are a direct evolution of the DW-5000C from 1983 — the first watch to survive the ten-metre drop test that defined the G-Shock project. Forty-plus years later, the silhouette is unchanged. The Fine Metallic edition adds a silver stainless steel bezel with dual-polished surfaces and a vivid red LCD, but the shape underneath is the same one that launched an entire category.
• At 76 grams and 12.9 mm thick, the GM-5600YRA is the lightest and most compact of the four Fine Metallic models. The GM-2100 is slimmer (11.8 mm) but wider (44.4 mm). The GM-5600 is narrower (43.2 mm) and lighter (76 g vs 84 g), making it the Fine Metallic that fits the smallest wrists and slides most easily under a cuff. If you want the Fine Metallic silver-and-red treatment in the most wearable size, this is the one.
• The vivid red LCD on the 5600's full-width digital display is the cleanest expression of the Fine Metallic colour story — no analog hands, no sub-dials, just red digital segments filling the recessed display window against the silver metal bezel. The simplicity of the layout lets the red-on-silver contrast speak for itself.
• Five-year battery on a CR2016, shared with the GM-6900YRA. The 5600 and 6900 both run pure digital modules (3525 and 3529 respectively) that outlast the analog-digital modules in the GM-2100 and GM-110 by approximately two years. Flash alert — the LED pulses in sync with alarms, hourly signals, and countdown timer alerts — is also shared with the 6900.
• The tough silicone band with urethane-film top surface and silver vapor deposition underside is consistent across all four Fine Metallic models. Stainless steel band loop components. The material quality doesn't scale down with the case size — the 5600 gets the same band treatment as the larger models.
• 200-metre water resistance and shock resistance. The origin of G-Shock toughness, in the silver Fine Metallic treatment.
