I've been going to him for my batteries at least 20 years. I have a Seiko around 20/25 years old, runs flawless. First time I tried to get a new battery, from many different Jewelry stores/watch repair. All the answers were we have to send it off to Seiko, or somewhere & was going to cost over $100.00, and would take 3 months for return, and no guarantee it would be waterproof!!! I found his number called asked the price for a new battery $5.00, and he guaranteed it wouldn't leak. After all these years and many many many battery changes (1 every 2 years) it still don't leak. I SCUBA dive & I'm in and around water all the time. I don't dive with it, but its always wet.
