Welcome to the analog G-SHOCK Master of G Frogman watches with composite bands.

Ç?ÇîÇ??

These watches are designed to perform for the diver, delivering both durability and lightness with a middle frame in fine resin for the GWF-A1000XC and carbon-reinforced resin for the GWF-A1000C. The composite bands are complemented by a buckle with extender to slip easily over a wetsuit.

These special Frogman watches make no compromises on style and color, either. Go with the beautiful blue ion-plated stainless steel bezel, with the second hand in vibrant, eye-catching yellow. Or opt for a one-of-a-kind design featuring splashes of color’??¶¦?from the single orange layer in the laminated carbon bezel to the inset dial ring in bold orange.
