The upcoming G-Shock MRG-B5000 is expected to have a new module, and that appears to be confirmed with the release of the English-language instruction manual for Module 3501 at support.casio.com. Although “MRG-B5000” is not mentioned, the HTML instructions have the “MR-G” logo at the top of the page, and the instructions are clearly for a 5000-series watch. (Update: The module is also listed as “3501” at a parts retailer, and leaked photos of the case back also confirm it.)
According to the specifications section of the manual, the module functions are identical to the GMW-B5000. Confirmed features include Tough Solar power, Multi-Band 6 automatic radio wave time adjustment, world time, stopwatch (24 hours, 1/100-second first hour, 1-second after first hour), countdown timer (24 hours, 1-second setting units), 5 alarms with 1 snooze, hourly time signal, 12/24-hour format, button tone on/off, power saving mode, and full auto LED backlight with adjustable 2 or 4-second afterglow. The Bluetooth mobile link feature includes auto time adjustment, one-touch time correction, phone finder, world time (approx. 300 cities), auto summer time switching, timer settings, alarm settings, and a reminder function for important dates. Also like the GMW-B5000, the date format is adjustable and the day of week is available in six languages.
Since it is just for the module, the instruction manual does not list the type of materials used for the case and exterior. It also does not list the level of water resistance. We continue to wait for an official announcement from Casio for more information.
For those who may bemoan the lack of new features for such an expensive ($3,500-$4,000) watch, it should be noted that the MRG-B5000 is expected to be built with superior materials and a redesigned bezel structure. The watch is also expected to be manufactured at the Premium Production Line of the Yamagata Casio “mother factory” in Japan and presumably in smaller quantities. The MRG-B5000 is not meant to replace the GMW-B5000, and it will be one of many options in a wide-ranging G-Shock lineup.
