I have a beautiful white-watch-face Citizen vintage Exceed watch that a friend gave me. I sent it to Hurley's Factory Authorized Service for servicing. They checked everything out and changed some gaskets. I am looking at some black-watch-face E510 Exceed watches on Ebay. There are about 5 for sale, all from Japan, and ranging in price from about $165 to $250. There are no description indications of wear and tear or running condition and the watches all look to be in good shape with only minor scratches. Any suggestions on deciding which one to buy? I plan to send the watch to the Citizen Factory Service Center after I purchase the watch.
