Casio G-SHOCK MR-G Frogman Series MRG-BF1000R-1A

The G-SHOCK MR-G FROGMAN MRG-BF1000 brings the iconic asymmetrical design of the FROGMAN family to a sophisticated full-metal titanium construction, with ISO water resistance up to 200 meters. Each component of the complex case is individually machined and finished to combine the typical G-SHOCK toughness with the refined aesthetic of the MR-G line.

The structure is made up of over 70 external components, featuring waterproof O-rings and special buffers that improve shock resistance. The fluorinated rubber buffers inserted between the bezel parts also help to protect the dial and glass from impacts.

The screw-lock case back is embellished with sapphire glass with a vibrant blue finish and an engraving of the iconic FROGMAN diving frog. The band is made of Dura Soft, while the buckle and band loop are made of Ti64 titanium.

The MR-G module integrates Bluetooth® and specific diving functions: in dive mode, the hour and minute hands overlap, forming a single hand that intuitively indicates the time spent underwater. Through the dedicated app, you can also consult tide data for over 3,000 locations worldwide and view dive logs on your smartphone.
