Product Details
Description
The Casio G-Shock GA-2100SB-1AER is a bold men's watch that combines the iconic octagonal design of the 2100 G-Shock series with a striking metallic silver-black look. The dial and index markers feature a circular hairline finish, then vapour-deposited with silver for a refined, metallic flair. The bezel and matte black resin strap create a strong contrast, lending the watch an elegant yet sporty character.
Despite its slim profile of just 11.8 mm, the GA-2100SB-1AER delivers proven G-Shock toughness thanks to the Carbon Core Guard structure. The watch combines analogue and digital time display and features world time across 31 time zones, a stopwatch, countdown timer, and five daily alarms. The dual LED illumination (Super Illuminator) ensures excellent legibility in the dark. Battery life is approximately 3 years.
