Tokyo, June 2020 — Casio Computer Co., Ltd. just put out a new addition to the FROGMAN series of shock-resistant G-SHOCK watches for divers. The GWF-A1000 is the first FROGMAN to feature an analog display and it comes with ISO 200-meter water resistance and mandatory asymmetric design to ensure unrestricted wrist movement underwater. Packed with new watch module and construction advancements, the GWF-A1000 is the first FROGMAN with an analog display.

The case is made of carbon fiber reinforced resin, which provides both the lightweight properties of resin and a strength similar to metal. The monocoque design, with seamless integration of the case and case back, further enhances the robust, lightweight specifications. The fluoroelastomer band also resists staining and deterioration due to reaction with water, which means the watch can be used for many years without worry. In diving mode, the user checks the dive time with this new analog model, the hour and minute hands overlap and move in unison to form a single hand, making the time spent underwater easy to see and intuitive. In order to quickly switch the hands from the current time to the elapsed dive time, Casio developed a new module with three dual coil motors. The Super Illuminator supports the user even in a dark spot. The watch can also automatically log diving spots and times. Once it is paired with a smartphone running a dedicated app, the user is able to review a record of their diving activities.
Every model since the series launch has included a frog icon engraved on the case back. The design on the new model features a playful frog with a prominent watch hand.

The first FROGMAN model, DW-6300, was launched in 1993. While maintaining the unique asymmetric shape, the series has continued to evolve with added features such as a more streamlined profile, solar-powered operation, reception of radio wave time-calibration signals, andsensors to measure water depth and more. FROGMAN is a series of full-fledged diver’s watches built to withstand demanding conditions underwater. To overcome the various challenges involved in creating FROGMAN, the development team actually obtained scuba diving certification and sought feedback from professionals involved in marine rescue.
