Hi, this auction is for a vintage SS Automatic Seiko Diver's watch. Works with movement- automatically. Locking crown, hands glide smoothly around and past each other. Unisex, measuring 1.5" overall with a 7/8" face, so it's suitable for a man that prefers a smaller size or great for a woman. This watch is in good used shape, but there are scratches throughout. Face is signed: "SEIKO; AUTOMATIC; PROFESSIONAL; 150; JAPAN 2205; -131LR," and the case back reads: "SEIKO; WATER RESISTANT; 8N1372; JAPAN - A; STAINLESS STEEL 2205 - 0769." Good luck and thanks for viewing my auction.
