Except for the "Snake Killer" and the "Carbon Fiber Frogman" (GW-201-6JF and GW-201NT-1JF), this Frogman has the Tough Solar 2422 module. The last GW-200 series Frogman is the GW-200Z-1JF "Final Frogman" that was released in November 2009. The model has been around for at least seven years, longer than the DW-8200.[citation needed] Typically, the "GW" designation refers to G-Shocks that can receive time updates from radio signals, which are commonly called, though incorrectly, "atomic signals" But, no Frogman has been equipped with this feature prior to the release of the GWF-1000.
