CASIO GWF-D1000B-1DR – FROGMAN

SPECIFICATIONS

These sensors provide real-time measurement data to support underwater search and rescue activities. The watch comes with an array of pro-grade features including a tide graph that displays high and low tides and a log memory function to track diving activities (dive time, maximum water depth, and lowest water temperature), supplemented by an excessive ascent rate alarm. The GWF-D1000 also takes a leap forward on the outside with features that enhance durability.

While retaining the asymmetric shape of past FROGMAN watches, the GWF-D1000 boasts a crystal made of scratch-resistant sapphire and a wristband reinforced with a carbon fiber insert. The watch features large buttons that are easy to operate even with gloves on.

The back case features a diamond-like carbon (DLC) coating and is engraved with a FROGMAN icon featuring a stylized rescue frog bravely diving into the dark seas with light in hand.
