All G-Shock Watches with Multi-Band 6 Wave Ceptor Auto Time
April 16, 2022
Multi-Band 6 (also known as Wave Ceptor or Radio Controlled) is a useful feature for those who always want the most accurate time on their watch. Although the quartz movements on G-Shock watches are already very accurate to begin with (with a plus/minus accuracy of 15 seconds per month), Multi-Band 6 ensures daily accuracy to the second by automatically (or manually) receiving time signals from a radio transmitter several times a day and adjusting the watch accordingly. (Though the watch itself is not an “atomic clock,” the feature is sometimes unofficially referred to as “atomic,” because the time standard being synced to is sourced from an atomic clock.)
The first G-Shock with the Wave Ceptor feature was the GW-100 from 2000, officially named Antman for its antenna, which was limited to receiving radio signals from one transmitter in Japan. The feature would later be expanded in other models to include support for more transmitters around the world and would eventually become Multi-Band 6 with support for transmitters in Japan (2), North America, United Kingdom, Germany, and China. Multi-Band 6 is now typically paired with Tough Solar power on G-Shock watches for truly maintenance-free operation. The downside to Wave Ceptor technology is that the range of the six radio transmitters makes it limited to certain regions (see coverage map by Casio) with a large part of the world not covered, and reception can be spotty or nonexistent in some locations, due to range or obstruction issues. Another possible downside is that there is no guarantee that all of the radio transmitters (which are controlled and funded by their respective country’s government) will remain in operation indefinitely, although we’d like to believe that they will. In 2018, a proposal was made for the 2019 NIST budget to defund and shut down the WWVB radio station in Colorado that serves radio-controlled watches and clocks in North America. Fortunately, that proposal never went through, but it did cause some major concern about the future of devices that depend on the technology.
With the proliferation of smartphones, G-Shock has been shifting towards the Bluetooth link feature which also provides automatic time adjustment through a phone’s internet connection. Not everyone desires or is able to use the Bluetooth feature, and some would prefer a stand-alone watch with Multi-Band 6. (It should be noted that it is possible to adjust and operate a Bluetooth-equipped G-Shock as a stand-alone watch without using Bluetooth and a phone, but the full range of features will be sacrificed.) Those interested in the Multi-Band 6 feature may also want to consider a G-Shock watch with GPS timekeeping, which receives time information from GPS signals that are accessible around the world.
The following are currently active G-Shock watches with Multi-Band 6. The feature is usually denoted by a “W” in the model name, except in the case of MT-G and MR-G models. Some models may not be available in all countries.
Affordable Analog-Digital Watches with Multi-Band 6
Unfortunately, there aren’t many choices when it comes to affordable (under $200) analog-digital G-Shock watches with Multi-Band 6.
AWG-M100: The main choice for an affordable mid-size analog-digital G-Shock with MB6 and the main solar analog alternative to the GA-B2100 (coming May/June 2022) which has Tough Solar and Bluetooth but not MB6.
AWG-M520: Based on the first-ever analog-digital G-Shock (AW-500). This model is usually sold in Japan only. The deluxe full-metal version AWM-500 was also released in other countries.
GAW-100: An extra-large model, not to be confused with GAS-100 which looks the same and has Tough Solar but not MB6. The GAW100B-1A is available in the U.S. at gshock.com with a discounted price of $128.
Digital Watches with Multi-Band 6
GW-2310, GW-2320: These models don’t get much attention outside of Japan, but they are highly regarded by those who own them. The GW-2310 has a stainless steel bezel ring. The GW-2320 has an aluminum bezel ring and is 2 grams lighter overall.
GW-6900: Usually one of the more affordable and popular MB6 models in America.
GW-7900: G-RESCUE model with large buttons and tide and moon graph. Not to be confused with G-7900.
GW-8900: Large size, available in Japan. Not to be confused with G-8900.
GW-9110 Gulfman: With tide and moon graph and external metal parts made of rust-resistant titanium. Available in Japan.
GW-9300 Mudman: With Twin Sensor (compass and thermometer). Not to be confused with G-9300.
GW-9400 Rangeman: With Triple Sensor (altimeter-barometer, compass, thermometer) and sunrise/sunset time.
GW-M500: The GWM500A-1 can often be found heavily discounted in the U.S.
GWX-5700: G-LIDE model with round face and tide and moon graph. Available in Japan.
GXW-56: Not to be confused with GX-56. The “GXW” version with MB6 is available in Japan and Europe.
MTG-M900: It is technically an MT-G model but is not a luxury model like recent MTG-B models. Available in America.
Origin 5000 Series Watches with Multi-Band 6
There are many “square” models with Tough Solar and Multi-Band 6.
GW-5000: With stainless steel screw-back case. Japan and Europe only.
GW-S5600: Lightweight model with carbon fiber band and titanium parts. Available in Japan.
GWX-5600: G-LIDE model with tide and moon graph. Available in Japan.
GMW-B5000: Full metal stainless steel or titanium (GMW-B5000T) with screw-back.
MRG-B5000: Kiwami (Peak) origin model made of titanium and Cobarion bezel.
G-STEEL Watches with Multi-Band 6
Newer G-STEEL watches have shifted to the Tough Solar and Bluetooth combination with the “GST-B” models, but some early “GST-W” models with MB6 are still available in some countries. (The U.S. received “GST-S” models with Tough Solar and no MB6.)
GST-W100/W110: Large-size analog-digital. Available in Japan and Europe.
GST-W300/W310: Mid-size analog-digital. Available in Japan.
Gravitymaster Watches with Multi-Band 6
GW-3000: Available in Japan and Europe, no LED light.
GWA-1100: With sapphire glass, compass, no LED light. Available in Japan.
