Introduction This is a Casio G-Shock Frogman GW-200MS, a solar-powered professional diver's watch rated to 200 metres, built on a titanium case with a full black finish and finished with the iconic Frogman multi-piece resin body. The dial carries a large digital time display in 24-hour format (17:xx), a day-of-week window (WED), a secondary time zone reading (9:30), an analogue tide/moon sub-dial at the 8 o'clock position, and the legends CASIO / DIVER'S 200M / MULTI SITE MEMORY / FROGMAN / TOUGH SOLAR. The caseback is engraved with the Frogman diver logo and stamped CASIO / GW-200MS / TITANIUM / DIVER'S WATCH 200M / JAPAN K / module 2422, confirming the titanium construction and Japanese origin. This example comes with its original BEAMS co-branded box. Historical / Era context The Frogman line is Casio's flagship professional diving G-Shock, introduced in 1993 and one of only a handful of G-Shock models to carry ISO 200-metre diver certification. The GW-200MS is a special collaboration variant produced with Japanese lifestyle retailer BEAMS, distinguished by its all-black stealth aesthetic with rose-gold-tinted display accents — a highly sought-after limited edition in the collector community. Powered by Casio's Tough Solar module 2422, the movement harvests energy from light and eliminates battery dependency, making it as practical as it is collectible. The titanium case, screw-lock crown guards, and oversized button guards reflect the rigorous engineering standard of the Frogman range. Condition The watch is running and keeping good time. The watch was checked running at the time of listing with a fresh battery. Battery life and long-term accuracy are not guaranteed. As a vintage timepiece it may benefit from a service. Case: The case, guards, and band attachment points show light to moderate surface wear consistent with previous use, including fine scratches on the resin guards and case flanks. The screw-down crown guards and button guards are intact. The matte black finish retains its overall appearance with no deep gouges or structural damage. The titanium caseback is clean and the engravings are crisp. Dial: The display is fully legible and all segments are active. The rose-gold tint of the display panel is consistent and attractive.
