it dont keep time what size of battery dose it take the light comes on if it is the bat how do i change it
Take it to a jeweler.
Matthew, I would call Nixon and set up a repair order. If you send it to them they will take a look at any other issues with the watch while they are in there replacing the battery. They will also pressure test it. Sending it back to Nixon will also keep your warranty in good standing.
