What am I looking for?

You are looking for small marks on the movement. Use a magnifier 4x should mostly do the trick but 10x can help. Try not to breath intot the movement when doing so. And do not leave you watch open to collect dust. only have it open for the shortest periode!

There can be signs or numbers on the watch or inside the movement under the balance wheel. Also it is possible for older watches (before 1950's) that these marks are on the dial side of the watch (under the dial).
