G-SHOCK GMA-P2126W-8A - Mid-Size Octagon
Grey is the colour that reveals a finish rather than hiding it, which is a confident choice on a watch this small.
The GMA-P2126W is a mid-size model in G-SHOCK's 2100 Series, in resin and bio-based resin, on a band of biomass plastics, measuring 40.5 mm across and 11.3 mm deep at 41 grams. It is a slightly wider variant of the small octagon, and it carries a plain monochrome treatment rather than a graphic one.
Grey across the face and band, case 46 by 40.5 mm. Skeleton hands run over a small LCD with Neobrite on the markers. Module 5730 gives world time, a stopwatch, a countdown timer and daily alarms, and runs three years on a single cell. 200 m water resistant.
Understated in a line that mostly is not. The one you wear when you do not want to be asked about your watch.
Perfect for: grey G-SHOCK watches, monochrome mid-size watches, small analog-digital watches.
