CASIO G-SHOCK FROGMAN BLACK GWF-1000-1JF
From the Master of G series, which specializes in functions intended for use in harsh environments, the FROGMAN model, which specializes in waterproof performance, is newly introduced as a solar radio timepiece.
With the newly developed receiving antenna and metal case, we have achieved the reception of standard radio waves from 6 stations around the world while incorporating a waterproof function for ISO standard 200 m diving. In addition, it has 10 log data memory, high-speed calculation tide graph and high precision moon data function. The operation button of the stopwatch, which is frequently used during diving, is enlarged to allow operation even underwater. The fully automatic EL light is used for the backlight, and the liquid crystal part emits vivid light simply by tilting the arm during diving.
The protection cover that covers the case from the backside, the band, and the bezel are fixed from the side with screws to improve impact resistance, and the band has no unnecessary bumpy shape to consider the wearing feeling. Equipped with many practical functions as an authentic diver's watch that can be used in the seas of the world.
