Pre-owned Casio G-Shock MRG Frogman MRGBF1000E-1A Yellow Double Anniversary Set Titanium Dive Watch
Pre-owned Casio G-Shock MRG Frogman MRGBF1000E-1A Yellow Double Annive
Double-anniversary commemorative design: MR-G FROGMAN in a special colour
This very special timepiece commemorates a pair of special occasions: the G-SHOCK 40th anniversary and the FROGMAN 30th. The MR-G diver’s watch, crafted with a passion for design befitting the flagship line of the G-SHOCK brand, features a titanium exterior with a multi-component structure and meticulous attention to detail — now in a hue that pays homage to the yellow used for the first FROGMAN. Offered in a limited edition of only 700 pieces worldwide in special sets that include an interchangeable titanium band and a dedicated tool for swapping out the bands.
Scratch-resistant, highly transparent sapphire crystal with an anti-reflective coating
Meticulous commemorative design
The concept colour is yellow, the hue featured on the very first FROGMAN, the DW-6300, and one of the colours that is symbolic of the line. The crown, buttons, and screws are treated with gold IP. Sapphire crystal is press-fit into the titanium screw-lock case back to ensure a highly airtight structure while maintaining the built-in antenna’s radio wave reception sensitivity. Casio passion for refinement down to the finest details is evident everywhere in the design, with gold vapour deposition, and engravings of the first-generation FROGMAN diving frog character, as well as the words “G-SHOCK 40TH” and “FROGMAN 30TH.”
*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.
Special set with a pair of interchangeable bands
The vivid yellow fluoro-rubber Dura Soft band is highly resistant to staining and hydrolysis. With its flexibility, it offers a comfortable fit on the wrist, as does the specially developed, interchangeable pure titanium band with its many moveable parts. Painstaking processes of treating each link with a deep-layer hardening process and diamond-like carbon (DLC) coating prior to assembly give the titanium band a high-quality, intricate makeup. The band is also extendable so it can even be worn over a wetsuit. Use the dedicated tool to remove the side pins while pressing the buttons on the lugs’ undersides to quickly and easily swap out the band.
Highly airtight titanium exterior with multi-component structure offering ISO 200-metre 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 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.

DETAIL1
Special packaging: Fitting for a limited edition
A decorative box presents the watch with a profound look and is set off with a badge commemorating the G-SHOCK and FROGMAN anniversaries. The included band mounting tool, made of stainless steel with a DLC coating applied to it, is engraved with MR-G and FROGMAN logos. It features a knurled design inspired by a watch crown motif.

DETAIL2
Clad Guard Structure adapted for diving
Protective components 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.

DETAIL3
Dive mode and tide graph mode: With full-analogue display
In dive mode, dive times and surface interval times are indicated by forward and reverse rotation of the hands. In tide graph mode, the watch displays tide graphs for about 3,300 points around the world along with local time. Functions useful for diving are offered with full-analogue display.
