Casio G-Shock MR-G Frogman MRG-BF100R-1A Diving Watch

You have seen the sleek, luxurious styling of the MR-G line. You have seen the rugged Frogman line of dive watches. Now imagine combining the two. What do you get? Well, you get this: Casio G-Shock MR-G Frogman MRG-BF100R-1A Diving Watch.

Aesthetically, the new Casio G-Shock MR-G Frogman MRG-BF100R-1A may have adopted the iconic Frogman’s asymmetrical form and the familiar dial design but materially speaking, it is entirely different from the Frogman you have known.

This MR-G Frogman boasts the highest grade of shock resistance yet. For those who don’t already know, the asymmetrical form has the case left biased so as not to get in the way of wrist movement when diving and it has become an iconic design element for the Frogman series.

The Casio G-Shock MR-G Frogman MRG-BF100R-1A touts a titanium case with a screw-lock case back, a titanium bezel, and in between, it has fluoro rubber material to absorb shock. The bezel is further treated with a deep layer hardening and a DLC coating.

Moreover, the dedicated MR-G module features a gold-plated retainer plate. Interestingly, the case back has a press-fitted sapphire crystal with a blue vapor deposition engraved with the Frogman diving frog character along with the usual case back labels. It is cool but not necessary for a dive watch feature. Sapphire – treated with anti-reflection coating – can also be found on the display, btw.

Titanium is not limited to major components; smaller components like the screws, buttons, and crown, are all titanium. It is really no expense spared when creating this dive timepiece. But of course, that expense is ultimately borne by the consumers. More on that in a bit.

The dive watch is paired up with a Dura Soft Fluoro rubber band with a Ti64 titanium alloy buckle and band loop. Casio said that the number of parts that made up the case alone amounted to 76 and it includes the o-rings and shock absorbers.

Functionality-wise, the Casio G-Shock MR-G Frogman MRG-BF100R-1A is equipped with Bluetooth, and the hour and minute hands will overlap and work in unison to form a single hand when in the diving mode for easy tracking of the minutes spent underwater.

In addition to dive mode, the watch also offers a tide graph mode. Other notables include water resistance to 200 meters (656 feet), built-in tough solar, radio clock MULTIBAND6, mobile link function, and anti-magnetic properties (JIS Class 1) – just to name a few.

The Casio G-Shock MR-G Frogman MRG-BF100R-1A Diving Watch supposedly should go on sale April 21, 2023, in Japan, for a grand price of 594,000 yen (about US$4,452) but last check, it is listed as “sold out” on the Casio Japan website. We are not sure what gives.
