Vintage Steampunk Cylinder Piston Mens Watch Futuristic Flip Cover Clamp Lid. Had a new battery installed and it is running. I still recommend getting it serviced. The lid/cover protects the crystal and covers the dial. You pull the pin and the spring lifts up the cover to reveal the dial. Very unique piece. Movement is made in Japan. No maker listed. Appears to be from the 90s. This came in a watch lot with other watches from that era. Has some scuffs and scratches from use.
