I got some water on it last week and I was afraid that it might ruin the watch. How much is a new battery? ,M: It's $5 and we not only change a battery, but also guarantee it for a year and if you have the watch cleaned here, we can guarantee it for an additional 3 months. ,F: That sounds like a good deal. I'll get my battery here. When will it be ready? ,M: Usually I can do it right away, but now I'm repairing lots of watches. Can you leave your watch here until 5:00 PM?
