Thank you for looking. This is a listing for a SCUBAPRO XTender dive watch. The battery has been replaced, and I am told that the operation has been confirmed. It has been used infrequently and is in generally clean condition. I am listing this on behalf of my father, who has retired from diving. I do not have specialized knowledge, so I cannot provide details. Please check the photos for the condition and accessories, and purchase with your understanding. If you have any questions or would like additional photos, please feel free to comment.
