Case 13 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?

Regulation is possible if you want it closer. On many movements it's a quick adjustment by a watchmaker. Can you check whether the losing rate is consistent or getting worse? A stable -8 is a good candidate for simple regulation. A growing loss points to something else, such as falling amplitude, and regulation alone won't fix that.
