The FROGMAN shock-resistant diver’s watch is known for its asymmetric design, crafted to allow unrestricted wrist movement underwater. The MRG-BF1000R, released in 2023, brought this unique form to life with a highly water-resistant titanium case. Its meticulous construction, including a polished finish down to the finest details, has earned it high praise.

Building on the MRG-BF1000R, the new MRG-BF1000RG draws inspiration from the goliath frog — the world’s largest frog — found in the tropical rainforests of West Africa. Its colors and design evoke a spirit of adventure, capturing the thrill of exploring untamed wilderness.

The khaki band, inspired by the coloring on the back of the goliath frog, is made with a soft, highly flexible fluoro rubber material, ensuring a comfortable fit. The beige indexes, evoking the coloring on the frog’s underside, are coated with Neobrite for excellent visibility even in low-light conditions. The titanium screw-lock case back is fitted with a sapphire crystal, finished with a vibrant green vapor deposition inspired by the eye of the Goliath frog, and maintains a highly water-resistant structure while preserving the built-in antenna’s radio wave reception sensitivity.

In dive mode, the hour and minute hands overlap to form a single hand, providing an intuitive, easy-to-read display of time spent underwater. Three dual-coil motors enable swift hand movement, allowing users to switch quickly from the current time display to dive time display, making this a truly practical diver’s watch.
