Still very excited with my hublot BB unico all black. But getting concern that the watch is running slow. I have noticed the watch slows down a few minutes when I take it off at night. It's been consistent now that I have wore it more to test it. I usually wind it 20-30 times before setting it, and wear it all day, but then a day or two later I see a few minutes delay. Any advice is appreciated or if I'm doing something wrong. This is not a watch I were all the time. But doesn't feel good knowing this issue exist. Is this an easy repair to take it to the boutique? Thanks.
