Casio G-SHOCK MR-G Goliath Frogman Series MRG-BF1000RG-3ADR

A precious all-metal G-SHOCK MR-G dedicated to the sea: the MRG-BF1000, titanium-clad and hermetic, with ISO 200-meter water resistance, joins the true dive watches in the FROGMAN family. Externally clad in titanium, the asymmetrical design of this watch is made up of separately machined and meticulously polished elements to bring MR-G quality to the FROGMAN line. Crafted from a combination of over 70 external components, the case includes a waterproof O-ring gasket that ensures the FROGMAN's exceptional water resistance and special pads that reinforce the shock-resistant structure. Dura Soft, a durable and comfortable fluorinated rubber, is used for the strap, and Ti64 titanium alloy for the buckle and strap loop. The green color of the band is inspired by the green Goliath frog, the largest frog in the world. This color combination, paired with the second and indicator hands in a striking high-visibility orange, creates a design that will unleash the explorer in you. The dedicated MR-G module features a gold-plated locking plate. The screw-lock case back features sapphire crystal finished with a red vapor deposition and engraved with the iconic FROGMAN diving frog character. This watch also offers superior functionality. It features Bluetooth® and three dual-coil motors for rapid rotation of individual hands to indicate dive times, for stress-free diving. The hour and minute hands overlap and work in unison to form a single hand when in dive mode, offering high visibility that makes minutes spent underwater easy and intuitive to see.
