This product is a used wristwatch for sale. Vintage diver's watch with original stainless steel double-lock belt. It is in working condition. The date can be changed by pulling the crown out one step. Crown operation is also smooth. The bezel rotates smoothly. The front is relatively clean, but there is some peeling of the plating on the back and near the crown, but there is no problem with the waterproof function. There is one inconspicuous scratch on the crystal. The inner circumference of the belt is approximately 16.5cm. Thank you.
