A reliable source has a new “Speed Model Series” listed for July 2021 in Japan. Though not all of the details are available, it includes three GW-M5610U models, one GW-5000U, one GW-S5600U, and one G-5600U.
Upon further searching, we found that the GW-M5610U-1 and GW-M5610U-1B are listed on some European retailer sites (as the GW-M5610U-1ER and GW-M5610U-1BER, €129 each). We also found a search result for the GW-5000U-1 from an official Casio retail site (as the GW-5000U-1ER, €299), but that page is not currently active. The original source has a GW-S5600U-1JF listed, but we could not find any other results for this or a G-5600U. No images are currently available, but they should be soon.
The GW-M5610 series features Tough Solar and Multi-Band 6. The G-5600 has Tough Solar but not Multi-Band 6. The GW-S5600 is known as the lightest G-Shock watch for men (47 grams) and has a titanium case back and carbon fiber insert band, with the GW-S5600-1JF being an active model in Japan. The GW-5000 has a screw-back case (like the original DW-5000C and other early G-Shock models) with DLC, and the GW-5000-1JF is an active Japan-only model that is popular with fans and watch enthusiasts around the world.
We’re not sure if “Speed Model Series” is the official name for this series, or if the original source gave it this name informally. We believe it is probably the latter. “Speed model” is often used in Japan to refer to a 5000 series watch, because of the DW-5600C worn by Keanu Reeves in the 1994 movie “Speed.”
Update: Based on some leaked images that we’ve seen, these models are the same colorways as their non-U counterparts, and based on a different LCD indicator (“LT” versus “A.EL”) and label (“Light” versus “EL Back Light”), it appears that all of these U models may have an upgraded LED light instead of the old style of EL backlight. More recent square models like the GMW-B5000 and GW-B5600 also have an LED backlight. The Google-cached page from an official European site for the GW-5000U-1ER has the module number listed as 3495, which is different than the GW-5000-1 (module 3159). The older non-U GW-M5610 and GW-S5600 models also have module 3159, so the GW-M5610U and GW-S5600U models are expected to have module 3495.
