G-Shock MRG-B2100B-1A: First 2100-based MR-G series is a $4,800 CasiOak

G-Shock MRG-B2100

Casio officially announced the G-Shock MRG-B2100 series to be launched in June with the debut of the MRG-B2100B-1A. The MRG-B2100 is the peak version of the 2100 octagonal line that began in 2019 with the GA-2100. The GA-2100 was an instant and massive hit, and the 2100 family quickly rose and expanded to become one of G-Shock’s most prominent “masterpiece” lines. The MRG-B2100 is the first MR-G series to be based on the 2100 line, and it is also the first 2100 series with a full analog display.

MRG-B2100B-1A Bezel

The MRG-B2100B-1A measures 49.5 (L) x 44.4 (W) x 13.6 (H) millimeters and weighs 122 grams. Although slighter thicker than the GM-B2100, it is 43 grams lighter due to its titanium construction. Unlike the full stainless steel GM-B2100 and similar to the MRG-B5000, the multipiece bezel is made of twenty-seven parts which are individually polished before assembly. The top section of the bezel is made of Cobarion, which is four times harder than pure titanium, and the band links are made of DAT55G titanium alloy. The other bezel parts and case are made of the superhard Ti64 titanium alloy. The external parts have a diamond-like carbon (DLC) coating for additional resistance to scratches. The display is a sapphire crystal with an internal anti-reflective coating. Like all MR-G models, the MRG-B2100B-1A is made in Japan at Casio’s Premium Production Line.

Another characteristic that sets the MRG-B2100 apart from other 2100 series is the dial design with a 3D textured pattern inspired by “kigumi,” which is the traditional Japanese woodworking method of interlocking wooden parts without using metal. The dial has a metallic black finish, and the spaces in the pattern allow light to pass through to the solar panels for the Tough Solar power system.

The watch is also equipped with Multi-Band 6 automatic radio time adjustment and Bluetooth smartphone link. Other features include shock resistance, 200-meter water resistance, magnetic resistance (JIS Class 1), Neobrite luminous hands and markers, and Super Illuminator LED light.

MRG-B2100B-1A Angle

The watch does not have an alarm, stopwatch, or timer, which is unusual for a G-Shock, but not unheard of when it comes to past MR-G models. It also does not have world time, but it has a time zone setting. It does have a date and day display with a full auto calendar. It does not have a battery level indicator, and the watch needs to be connected to the Casio Watches smartphone app to check the battery level, but there is a low battery alert in the form of the second hand jumping at two-second intervals. Other functions of the Bluetooth connection with the smartphone app include automatic summer time (DST) switching, auto and one-touch time correction, phone finder, hand alignment correction, and the time & place log. Not mentioned in the listed specifications but according to the instruction manual, the duration of the Super Illuminator LED light can be set to 1.5 or 3 seconds, which requires using the Casio Watches app to adjust the setting. (The default setting is likely 1.5 seconds.)

The MRG-B2100B-1AJR will be released in Japan on June 14 with a tax-included price of 649,000 yen (around $4,100). Release information for other countries is expected to be announced soon.

Update: G-Shock U.S. has the MRGB2100B-1A listed as coming soon for $4,800.
