Casio G-SHOCK MR-G Frogman MRG-BF1000B-1A

A prestigious all-steel G-SHOCK MR-G also suitable for the sea: the new MRG-BF1000, titanium-clad, with ISO 20-bar water resistance, joins the true dive watches of the FROGMAN family. This MR-G diver's watch features a unique asymmetrical design and a screw-lock case back. Moreover, the case back features the characteristic FROGMAN diving frog character. Originally produced in resin, this timepiece has been re-made in titanium, with each component meticulously crafted for a high-quality, completely new look. The watch is built with a complex combination of over 70 external components, including a waterproof O-ring that ensures the exceptional FROGMAN water resistance and special buffers that strengthen the shock-resistant structure, all while maintaining the beautiful form for which the MR-G line is known. For added strength, we developed a protective structure with fluororubber buffers installed between the various bezel parts. This structure features a dial protection function that helps absorb shocks to the front and sides, as well as protecting the glass. The watch module features a gold-plated locking plate. The screw-lock case back features sapphire glass treated with a red vapor deposition technique and has the FROGMAN diving frog engraved on it. The titanium band is finished with a deep-layer hardening process and DLC coating. The strap is also extendable, so it can be worn over a wetsuit. Not only aesthetically beautiful, this watch also offers many functionalities. Equipped with Bluetooth®, the hour and minute hands overlap and work to form a single hand in dive mode, showing the elapsed minutes underwater easily, intuitively, and clearly visible. Download the dedicated app to pair it with your smartphone and easily view tide data for over 3,000 locations worldwide. Check your dive logs on your smartphone and get more details on the data recorded by the watch.
