Make your statement cool, contemporary, and sporty, with vivid accent colors that pop. 

With the GMA-P2100SA, we start with classic black and add accents in vibrant hues inspired by athletic gear to create a striking contrast that delivers full-on sporty style. 

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.

The watch features hour marks accented in neon yellow or red, plus watch hands featuring the same color and coated in a similar phosphorescent hue. These colorful details add a vibrantly individualistic flair to the watch’s octagonal form and streamlined, all-black design.
