If an automatic is initially running fast is it likely to change after an initial "breaking in period"? If so, how long a breaking in period is typical and how much change might occur? My watch is running about 18 seconds fast per day and I'm wondering whether to try to regulate it or just wait and see. Placing it in different positions at night does not seem to make a difference.

If you are hoping for it to be fixed then i say wait a week? If you want to reach a quick conclusion go get it regulated. To be honest it depends on the watch, 18/day isnt that bad. My Tag Carrera does +15 per day, i dont bother to get it regulated

Who told you that a watch has a break in period?

There ain't no sych thing as a break in period for watches. There is a combination of bringing the watch to full wind over a couple of days and the owner getting used to his new mechanical watch and the inherent variability of mechanical watches. Just wear the watch for a couple of weeks. Then set it to time.gov and check the cumulative error after 7 full days. If the average daily error is beyond 10 seconds consider having it adjusted by the manufacturer or authorized dealer.

Yes it is ...my tolerance is +/- 3 sec per day.

That's kinda big. My 45-year-old Omega is sitting at maybe +2-3/day after getting regulated. If I got a newer watch that performed worse, I'd get it adjusted, too.

Depends, if i got 18/day from my Zenith for example, id be pretty upset. Considering my Tag is non COSC and a simple Valjoux 7750. 15/day isnt the biggest deal. It just depends on personal tolerance. I tolerate depending on how much i pay.

18 seconds a day is a bit much, IMHO. Normally, I give my new watches a month of solid wear before I make any judgments on accuracy.

Your tolerance notwithstanding, for most lower-end mechanical movements, +18s/day is within normal specs. I believe Seiko's 7S26 and Citizen's 8215, for example, are rated within +40/-20.

+18 is not too far outside the factory adjustment for standard grade Swiss movements like the ETA 2824-2, either.

The OP hasn't said what kind of watch he has, but depending on the make, grade, and age of the movement, +18 might be completely normal.

i did some research regarding the +15/day on my valjoux 7750....in conclusion, completely normal and within specs. If you go up to brands like GO, watchmakers would probably get shot for such a spec :p

This seems to be true. My Seiko 5 was insanely accurate. But now it has been sitting stopped for several weeks and when i re-run it some time ago, it wasn't as accurate anymore.

Yes, cuz it's universal principle to every mechanical system.
But no to you, cuz very often, break-in already starts during transportation in distribution, that's before you purchase the watch.
