The first time I took it out of the box I wound it 30 times and when I tried to pull the crown out to set the time it was very difficult and would pull out past the gears, or before them. It seemed like I had to push it to an exact distance to get the dial to finally turn, and even when it did it didn't feel like it was turning clean. It felt like the gear was skipping. I got it to the correct time though and wore it for a couple days and kept dropping the time an hour or more, even though I wore it all day. I contacted support and told them. They told me to wind it 30 times again, and do the same thing. I did, and got the same result. The time was about 3 hours off after 48 hours despite me wearing it all day.
