Compact, streamlined, stylish — the GMA-P2100 sparkles like the summer sun. Treated with polarized vapor deposition, the watch glass delivers a sun-drenched summertime vibe with colors that change with a tilt of the wrist. Paired with a translucent case and band, the design evokes the light, refreshing feel of a summer resort. The compact design fits smaller wrists with total comfort. This special design will take you wherever you want to go — from everyday fun to high fashion. Each timepiece features a unique gradation of hues due to the nature of the special vapour deposition process applied to the glass. Note that, depending on the ambient light, the dial may be difficult to read at certain viewing angles.
