Description
CASIO GMC-B2100Y-1AER is a powerful men’s chronograph from the G-Shock Full Metal series, carrying forward the legacy of the legendary first G-SHOCK from 1983 in a full-metal execution. The black dial with three subdials is framed by an octagonal stainless steel bezel, shaped through a time-intensive forging, cutting, and polishing process that combines a circular hairline finish on top with a mirror polish on the slopes. The new-style tough silicone band with a gunmetal-colored metallic vapor deposition finish combines durability with wearing comfort, while solar power and Bluetooth connectivity make this watch a truly modern tool.
The 51.3 × 46.3 × 12.4 mm case is made of stainless steel with shock-absorbing resin buffers between the bezel and case and complemented by a tough silicone strap with a metallic finish. The model features a Casio Module 5733 solar-powered quartz movement with a chronograph function, dual time, and smartphone link.
