When your B01 is not on your wrist, where is it?

Unless you have a timing machine, you will need to run some tests against an accurate source of time. There are several internet sources.

The six positions are du, dd, pu, pr, pd, pl where d = dial and p = pendant or crown; and the second letter refers to position, up down, right and left. Since you wear it daily, check the time when you take it off and place it in one of the positions overnight. Check the time again in the morning. You should see a slight difference between positions since no movement will draw a straight line in all six. Place it in the position where it gained the most (or lost the least) time to attempt close the time difference.

Regulating a watch on a timing machine is not difficult, but it can be time consuming. Almost all movements will have slight cyclical changes at the revolution rates of the train wheels. The amplitude of the change can only be determined by leaving the watch on the timer for at least an hour, preferably two. The reason this is important is you don't want to try to adjust the rate when it is at one peak or the other.

If you brought the watch to me and asked me to adust it to slightly gain time vice its current rate, I would probably keep it on the machine for quite a while before attempting any adjustments. It's not a ten minute fix, although people seem to think so. If a watchmaker tells to to come back in 30 minutes to pick it up, take it somewhere else!
