Casio G-Shock MR-G Frogman MRG-1100 – Full Titanium Diver’s 200m, Circa 1999–2000
The Frogman is G-Shock’s only ISO-style diver, and the MR-G line was Casio’s premium, all-metal take on the G-Shock. The MRG-1100 brought the two together: a Frogman built entirely in titanium, made in Japan, at a time when nearly every G-Shock was resin. Original examples are now firmly collector territory, especially with the full titanium bracelet intact.
The case and bracelet are brushed titanium, with a polished bezel and a blue anodised ring framing the dial. The display combines a digital readout with a small analog-style dive-time subdial at 9 o’clock. The bezel is printed with the Frogman’s dive functions: Site, ID, Alarm, Timer, and Stopwatch, plus dive mode and auto light. The caseback carries the engraved Frogman mascot and the Diver’s Watch 200m rating, along with Casio’s “authorized service center repair only” warning.
Inside is Casio module 2036, which runs the time and calendar, dive time and log data, dive site and ID memory, three alarms, a countdown timer, and a stopwatch.
