Casio to release metal shock-resistant diver's watch in vibrant yellow
Double-anniversary design commemorates both G-SHOCK and FROGMAN anniversaries
With interchangeable metal band

Norderstedt, 20 June 2023 — Casio Computer Co., Ltd. today announced the release of a special watch available worldwide in a limited edition of only 700 pieces, commemorating the 40th anniversary of the G-SHOCK and the 30th anniversary of the FROGMAN. The MRG-BF1000E is a metal shock-resistant diver's watch featuring vivid yellow.
This year marks the 40th anniversary of the Casio G-SHOCK brand. The FROGMAN line of shock-resistant diver's watches, popular for their unique asymmetrical form, also celebrates its 30th anniversary this year. Casio has released new models to commemorate these anniversaries. This spring and summer, Casio released the MRG-BF1000R—a timepiece that clads the unique FROGMAN form in titanium—as part of the MR-G line, the flagship line of the G-SHOCK brand.
The MRG-BF1000E builds on the MRG-BF1000R, bringing in a vivid yellow reminiscent of the first-ever FROGMAN colour design, for a metal shock-resistant diver's watch befitting this special double anniversary.
In addition to the vivid yellow used for the strap and index marks, the crown, buttons and screws are treated with gold ion-plating and the case back is finished with gold vapor deposition. An interchangeable metal strap is included in the package. Painstaking processes of treating each link of the strap with an abrasion-resistant deep-layer hardening process and diamond-like carbon (DLC) coating prior to assembly give the strap a high-quality, intricate makeup. Packaged in a special box with G-SHOCK 40th and FROGMAN 30th badges, this timepiece is more than just a watch — users can enjoy displaying this limited edition watch as part of their collection of G-SHOCK favourites.
Same as the base model, the hour and minute hands overlap to form a single hand in dive mode, making it easy to see how much dive time has elapsed. The watch's three dual-coil motors make it easy for users to switch quickly from current time display to dive time display, making this a truly practical diver's watch.
