Beautiful watch for the money.
Color: Big Dial Gold White Men Watch
This was a beautiful watch purchased at a great price. When I received it, it was not working.
I suspected that it needed a battery. I sent it back and got a refund. I have considered repurchasing the watch again, as it looks like an expensive time piece.
