G-SHOCK GMA-P2100M-2A - Mid-Size Octagon
G-SHOCK GMA-P2100M-2A - Mid-Size Octagon
Casio does not often build a gradient into a G-SHOCK dial. When it does, the watch stops looking like a tool and starts looking like an object.
The GMA-P2100M is a mid-size model in the 2100 Series, in resin and bio-based resin with a band moulded from biomass plastics. At 40.2 mm across, 11.2 mm deep and 40 grams, it is the smallest and lightest octagon G-SHOCK makes.
The face runs navy through blue to light blue with pink gold accents, on a band carrying the same graduation. The case is 46 by 40.2 mm. Skeleton hands sit over a small LCD with Neobrite on the markers. Module 5730 covers world time, a stopwatch, a countdown timer and alarms, running three years on a single cell. 200 m water resistant.
The prettiest thing in the 2100 line, and still rated to 200 metres.
Perfect for: blue gradient G-SHOCK watches, small lightweight watches, mid-size analog-digital watches.
