Casio Men's Octagonal Case G-Shock in Aluminium GM-2100B-3AER
Casio G-Shock GM-2100B-3AER
This Casio Men's G-Shock GM-2100B-3AER watch is constructed with a distinctive octagonal case made from aluminium. The dial beneath the hard-wearing mineral glass has a metallic sheen, created by a specialist vapor-deposited finish for a sharp, clear display.
Engineered for durability, the watch incorporates Casio's Hollow Core Guard Structure, which protects the internal module from shocks and impacts. This robust design also provides water resistance to 200 metres, making it suitable for a wide range of water-based activities.
The watch is equipped with a range of practical functions, including world time, multiple alarms, a stopwatch, and a countdown timer. A hand-shift feature temporarily moves the analogue hands for an unobstructed view of the digital display. The design is completed with a durable resin band and is powered by a battery that provides an approximate three-year lifespan.
