G-SHOCK GA-B2100-1A - Analog-Digital Octagon
The GA-2100 needs a battery every three years and a button sequence every time you cross a border. The GA-B2100 needs neither.
This is the connected member of G-SHOCK's 2100 Series: the same thin Carbon Core Guard case in carbon-reinforced resin, with Tough Solar under the dial and Bluetooth inside. Solar means the case is never opened for a battery; mobile link means the CASIO WATCHES app sets the time, so world time and daylight saving stop being your problem.
All black, 45.4 mm across and 11.9 mm deep, 52 grams. Skeleton hands over an LCD with Neobrite markers and a double LED. Module 5689 covers world time across 38 zones, a stopwatch, countdown timer and daily alarms, and holds fifteen seconds a month with the phone link switched off entirely. 200 m water resistant.
The version of the 2100 you set once. Everything the standard model does, minus the maintenance.
Perfect for: solar G-SHOCK watches, Bluetooth connected watches, thin black analog-digital watches.
