Citizen Alarm Diver, working condition, vintage. The dial is clean. There are scratches on the glass. The bezel rotates in both directions. The crown has a C mark. The alarm works. Regarding accuracy, I haven't checked it for a long time, but it was roughly accurate for about 12 hours. It's a diver's watch, but I don't think it's waterproof. The strap is made by Maruman.
