CASIO G-SHOCK Frogman GWF-1000-1JF Please check the CASIO HP etc. for specifications and functions. For those who want it, a GD-400 (new battery and packing) is included, see photo 9. I think it's a good condition item, but the perception varies from person to person, so please judge for yourself from the photos. Price negotiations from comments will not be accepted, please use the system's "price reduction request". GA-2100/GA-B2100 custom production, please consult for windproof glass, hands, dial replacement, etc.
