Soak up the shimmer of a timepiece inspired by gorgeous summer sunsets. The glitter of the sun going down over the water at the end of a beautiful summer day is captured using vapor deposition in a lustrous gradation of new colors on the dial. We begin with the GMA-P2100, an even more compact version of the popular digital-analog combination GMA-S2100, and adjust the length of the band to better fit slimmer wrists. We eliminate the original 9 o�÷??clock inset dial for a streamlined, minimalist look, and use stainless steel for the buckle and side buttons to add a touch of luxury. 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. New colorways bring luxe resort flair to your wrist and wardrobe, while environmentally responsible materials keep the beauty of the beach front and center.
