This is the first model (DW-6300 series) of Casio's "G-SHOCK FROGMAN" that appeared in 1993. Features: It is a full-fledged diver's watch with 200m diving water resistance compliant with ISO standards. Design: The asymmetrical case design is a distinctive feature, and it is a representative model of the MASTER OF G series. Rarity: The first model is very popular among collectors and is a valuable antique item. I have kept it stored at home after purchase. Upon listing, I replaced the battery with a new one on February 28, 2026. Operation has been confirmed. I am not familiar with the details, so everything in the images is included. Thank you for your consideration.
