Omega constellation watch is broken

My Omega watch is broken. What should we do?

This should not be returned. It should be repaired by the maintenance department of the specialty store. Generally, it should be free if you don't change it, but please be sure to bring a warranty card. By the way, the reasonable error of a mechanical watch is +-45 seconds per day, and if it exceeds it, it is unqualified. However, if Omega has an observatory card, the reasonable error should be within -4 seconds and +6 seconds per day.
