I recently purchased a Nomos Tangente, my first mechanical watch. I love it and am happy with the time it keeps, although it does run +6 per day. So, I have some questions:
1. Can any mechanical watch, including mine, be regulated? Is that expensive?
2. Will my watch "break in" and become more or less accurate over time?
3. Why are watches more likely to run fast than slow? (I often see people quote standards of +5/-3 or similar, and the + is generally larger than the -.)
