Enjoy the ever-popular digital analogue G-SHOCK look with a fit more comfortable than ever.

The GMA-P2100 takes the already compact GMA-S2100 design and makes it even slimmer and more compact, with a shorter band length, as well, to fit smaller wrists with total comfort. Monochromatic finishes in vibrant colours — dynamic turquoise blue (new colour), bright pink, and classic white — lift the spirit, and the 9 o’clock inset dial from the original GMA-S2100 is left behind for a streamlined, minimalist look.

The stylish, yet practical watch face features a dial, logo, index marks, hands, and other components finished in different shades of the same colour, simultaneously projecting sophistication and ensuring an easy read.

The bezel and band of these watches are made with bio-based resin produced from renewable organic resources, a material expected to help curb CO2 emissions and otherwise reduce environmental impact.

Vibrant monochromatic colour schemes

From the case to the band to the watch face, the entire watch is finished in a vibrant monochromatic colour scheme. Light and dark shades of the same colour are used for different components, including the dial, index marks, and hands, to give the streamlined face without inset dials a look that is both highly expressive and easy to read.

Attention to materials: Bio-based resin

Key resin components used in the bezel and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.
