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 vapour deposition in a lustrous gradation of new colours on the dial. We begin with the GMAP2100, an even more compact version of the popular digital-analogue combination GMAS2100, 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 colour-ways bring luxe resort flair to your wrist and wardrobe, while environmentally responsible materials keep the beauty of the beach front and centre.

Dial with colour gradation inspired by sunset

The dial and index marks are finished with vapour deposition. The dial features colour gradation, in pink, gold, or blue on different models, each of which recalls how the sky changes from hour to hour as dusk becomes twilight, then sunset. The matte urethane exterior lets the sunlight’s lovely twinkle take centre stage.

A compact size that’s easy to wear

The GMA-S2100, already a smaller version of the GA-2100, is now even more compact. The length of the band has also been adjusted for easier wearability, resizing this timepiece to comfortably fit even slimmer wrists.

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.
