Target: Men's Allergy Resistance : Not confirmed by the manufacturer or may not be suitable for allergy sufferers. Country of origin: Japan Water resistance : Water resistant to 200m Case size: 58.3 mm x 52.8 mm Moon data to show the age of the moon Calendar function Digital dial Radio wave receiving function Details: Product Introduction From the Master of G series, which specializes in functions designed for use in harsh environments, comes the FROGMAN, a new solar-powered radio-controlled watch that specializes in waterproof performance. With a newly developed receiving antenna and metal case, the FROGMAN can receive standard radio waves from six stations around the world while being water resistant to ISO 200m. Furthermore, the watch is equipped with 10 log data memories, a high-speed calculation tide graph, and a high-precision moon data function. The operation buttons of the stopwatch, which are frequently used during diving, have been enlarged to enable operation even underwater. Fully automatic EL light is used for the backlight, and the LCD emits brilliant light when the arm is tilted, even during diving. The protection cover covers the case from the back side, and the band and bezel are fixed with screws from the side to improve shock resistance, while the band is designed to be comfortable to wear by eliminating unnecessary unevenness. The band is designed to be comfortable to wear by eliminating unnecessary unevenness.

Equipped with the latest technology, the New FROGMAN is a practical and high quality addition to the Master of G series that can withstand the rigors of use at sea. Multiband 6 that receives and corrects the time of standard radio waves from 6 stations around the world (2 stations in Japan, China, the U.S., the U.K., and Germany) - Tough Solar - ISO standard 200m diving water resistance function - Tide graph that shows tide information for the set area - Moon data that shows the age of the moon for the set area - Screw back metal with DLC treatment to strengthen wear resistance Screw back metal case with DLC treatment to enhance wear resistance Brand Introduction G-Shock has established a new concept of toughness in watches. It all started with the passionate determination of the developers to create a watch that would not break even if dropped, a challenge that defied the common wisdom of the time. This was the birth of the technology at the heart of toughness. Since then, G-Shock has continued to evolve without end. Structure, materials, and functions. G-Shock has never stopped pursuing toughness in every aspect.
