I didn't think I needed this for my Breitling, but it was a gift from my wife, so . . .

I typically don't wear the watch on weekends, so have to reset it on Monday. With this, I put my watch in on Friday and it's set right on Monday. $99 may be a lot to keep you from winding your automatic watch when you don't wear it over 36 hrs, but I found it to be worth it. If I lost it, I'd buy another.
