This product is for the sale of one used wristwatch. Vintage diver's watch with original stainless steel double lock belt. It is in working condition. Date can be changed by pulling the crown out one click. Crown operation is smooth. Bezel rotation is also smooth. The front is relatively clean, but there is plating peeling on the back and near the crown. However, this does not affect the waterproof function. There is one small, inconspicuous scratch on the crystal. Inner circumference of the belt is approximately 16.5 cm. Thank you for your consideration.
