Casio dive watch from the 1980s, made for the Japanese domestic market. Watch features all stainless steel case, measures approximately 37mm. Bidirectional rotating bezel. High grade ETA quartz movement. I googled this particular model and the Swiss movement version is quite coveted. Fresh battery was installed in March 2025. Runs great. New bezel gasket seal installed around the same time. Note under the bezel is a tension spring (see picture 8), push down on the bezel as you rotate it for better action. Comes on a set of Barton strap, a $20 value. Some minor scratches on the crystal, but overall it's in great condition for its age. Shipped via usps ground.
