A premium, full-metal G-SHOCK MR-G timepiece for the sea — the titanium armor-clad MRGBF1000 with ISO 200-meter water resistance — joins the FROGMAN family of full-fledged diver’s watches.

Clad in a titanium exterior, the complex asymmetrical design of this timepiece is made up of separately crafted and meticulously polished components to bring luxe MR-G quality to the FROGMAN line. Built with an intricate combination of over 70 exterior components, the case includes an O-ring waterproof seal that delivers outstanding FROGMAN water resistance as well as special buffers to strengthen the shock-resistant structure.

Dura Soft, a durable and comfortable fluoro rubber, is used for the band, and Ti64 titanium alloy for the buckle and band loop. The green color for the band is inspired by the green goliath frog, the largest frog in the world. This color scheme, paired with seconds and indicator hands accented in striking, high-visibility orange, makes for a design sure to unleash your inner explorer.

The dedicated MR-G module features a gold-plated retainer plate. The screw-lock case back is fit with sapphire crystal finished in green vapor deposition and engraved with the iconic FROGMAN diving frog character. 

This timepiece provides superior functionality, as well. It is equipped with Bluetooth® and three dual-coil motors for rapid rotation of individual hands to indicate dive times, keeping your diving stress-free. The hour and minute hands overlap and work in unison to form a single hand when in diving mode and deliver the high visibility that make the minutes spent underwater easy and intuitive to see. Check dive logs on your smartphone and get more details on data tracked by your watch.
