G-Shock MRGG1000 still available in the U.S. and why its GPS timekeeping is unique


The G-Shock MRGG1000B-1A (2015) and MRGG1000B-1A4 (2017) are still available in the United States, and this an unusual case of high-end models being available in the U.S. but not Japan. According to Casio Japan, the Japanese models have ended production, so we can’t imagine that they will be available in the U.S. for much longer. Other than being a Japan-made titanium MR-G watch, one of the selling points of the MRG-G1000 is that it is one of the few G-Shock series with the GPS time adjustment feature that can sync anywhere in the world. It is also the only remaining series with GPS timekeeping and without Bluetooth. (The discontinued GPW-1000 and MTG-G1000 also fit that profile.) The MRG-G1000 also has Multi-Band 6 as its primary method of automatic time adjustment, but reception of the Multi-Band 6 signals are limited to certain regions (with transmitters in North America, Europe, Japan, and China).

The MRG-G1000 and Bluetooth-equipped MRG-G2000, along with the recently discontinued GPW-2000, have an advantage over other recent G-Shock series with GPS timekeeping in that the GPS time signal can be automatically received once per day if there is no Multi-Band 6 signal available. Recent series that only have manually-initiated GPS time adjustment include the G-SQUAD GBD-H2000 and Rangeman GPR-H1000. The previous GBD-H1000 and GPR-B1000 series did have automatic GPS time adjustment, and it may have been removed from their successors due to battery life concerns. The instruction manuals for G-Shocks with the GPS timekeeping feature state, “GPS signal reception requires large amounts of power. Perform it only when necessary.” GPS time adjustment is intended as a backup to the Multi-Band 6 and Bluetooth methods. Unlike the MRG-G1000 and MRG-G2000, the GBD-H2000 and GPR-H1000 do not have Multi-Band 6 radio time signal reception, but they can automatically sync the time through a Bluetooth connection to a smartphone. An advantage of the GBD-H2000 and GPR-H1000 is that they can also receive and display position information in the form of latitude and longitude coordinates, and they also use GPS to measure distance for their fitness features.

The G-Shock MRGG1000B-1A and MRGG1000B-1A4 are available in the U.S. for $3,000 each.

The MRG-G2000 series also appears to be discontinued in Japan, with the G-Shock Japan MR-G page displaying no MRG-G2000 models. The MRGG2000R-1A is also still available in the U.S. for $3,000. The MRG-G2000 has three-way time syncing with Bluetooth, Multi-Band 6, and GPS.
