Hi everyone. I just got my first automatic watch (Tissot Le Locle) last Monday. I wore it everyday during the weekdays and noticed that it was going +4 secs/day. I didn't wear it this past weekend. It was just lying flat on my desk and it was going at +10 secs/day.
My question is, are auto watches more accurate when worn? If so, what's the reasoning behind this? Thanks.
