I purchased this item new on Yahoo! Auctions. It has been used only to the extent of trying it on. I have removed the film from the back cover. I bought it thinking it was a radio-controlled solar watch, but it turned out to be a Tough Solar model. I do like it, but I need a radio-controlled solar watch for work, so I am listing it for sale. The warranty is included, but it appears to be expired. The item is in very good condition. Thank you for your interest.
