Features of the G-SHOCK MR-G FROGMAN Titanium Dive Watch
FEATURES
Highly airtight titanium exterior with multi-component structure offering ISO 200-meter water resistance
Lightweight, rust-resistant titanium is used for key exterior components — from the case, bezel, and case back, to the crown, buttons, and screws. The watch is made up of an intricate combination of over 70 exterior components, achieving a powerful and beautiful form. A protective structure offers face-guarding functionality with buffers made of fluoro rubber installed in the space between the bezel and case. A deep-layer hardening process and diamond-like-carbon (DLC) coating provide even greater strength and abrasion resistance. The case incorporates a crown and case back that both feature a screw-lock construction. These and other features throughout the design keep the watch air-tight to ensure water resistance for diving.

Titanium band designed for textural appeal and fit
The watch features a specially developed titanium band that offers a comfortable fit on the wrist thanks to its many moveable parts. Every link is painstakingly treated with a deep-layer hardening process and DLC coating prior to assembly, giving the band a premium-quality, intricate finish. The band is also extendable so it can even be worn over a wetsuit. Simply remove the side pins while pressing the buttons on the lugs’ underside to quickly and easily swap out the band.

Screw-lock case back made with an inventive combination of materials
Sapphire crystal is press-fit into the pure-titanium screw-lock case back, ensuring a highly airtight structure while improving the built-in antenna’s radio wave reception sensitivity. Casio passion for refinement, down to the finest details, is evident everywhere in the design, including an engraved first-generation FROGMAN diving frog character.
*Due to the screw-lock construction of the case back, the orientation of the logo and lettering on it may not match up perfectly with the dial.



Deep red accent color for a striking sense of presence
The dial ring and inset dial ring feature accents in the G-SHOCK brand color of red, creating a vibrant contrast with the base tone of black to express both strength and beauty. Red vapor deposition is applied to the case back’s sapphire crystal as well.

DETAILS
Clad Guard Structure: Adapted for diving
Protective parts are built into the crown and buttons to help absorb impacts to the module. The crown features an airtight screw-lock construction and incorporates buffering components made of highly water-resistant fluoro rubber. A special construction keeps the MR-G logo, engraved on the crown, horizontally aligned when the crown is screw-locked
