Thank you for viewing. This is a listing for a diver's watch, Royal Ace quartz wristwatch, with date function, being sold as junk. It has diver's specifications, with a screw-down crown. The band has a double hinge, and the bezel rotates. While the water resistance may not be as high as a full-fledged diver's watch, I think it should be sufficient for light sports. The battery is dead, so the operation has not been confirmed. Also, the decoration on the bezel (last photo) is missing, and the crystal is cloudy. My wrist size is approximately 18cm. This product is approximately 19cm. Please understand that there may be slight variations due to amateur measurements. Please understand that this is a junk item and a used item. Thank you for your consideration. Thank you for your interest.
