Casio G-Shock Analog Frogman ISO 200M Diver's Watch


The very first Casio G-Shock Analog Frogman GWF-A1000 Series of MASTER OF G ISO 200m diver!

The new GWF-A1000 has kept the asymmetrical design, and removed all traditional digital elements in exchange for a retro physical hour and minute hand analogue impression!

In addition to great designs, these new models incorporate modern tech infrastructure as well as advanced functions. This model incorporates the case and back cover into a single unit with carbon fibre-reinforced resin. It has a low water absorption coefficient and resists hydrolysis, which results in a higher level of water resistance and greater strength. GWF-A1000 is 22 grams lighter! Sapphire crystal with a non-reflective coating is a major improvement.

The fluoroelastomer band is dirt-resistant and has a low water absorption coefficient, and the band ring is made of an even harder fluoroelastomer. The result is a band and ring that can stand up to some of the toughest environments imaginable.

The GWF-A1000 featured a new module that has an always-connected Bluetooth system;

A G-SHOCK Connected app can be downloaded to a smartphone and linked to the watch. Of course, Casio’s famous Tough Solar and Radio-controlled Watch with Multiband 6 is a must!
