If your watch lost 5 seconds in 5 days, this comes out to -1 sec/day, which is well within COSC specs. Omega's instruction manual does say that any Omega watchmaker can regulate your watch to within -1 to +6 sec/day. However, a certified chronometer like your watch is tested to stay within the actual COSC specs of -4 to +6 sec/day (Omega's specs of -1 to +6 sec/day are tighter than COSC specs). Anyway, since the watch is new and you haven't had enough time to experiment with all of the different overnight positions, I would do this first. After all, if you say it lost 2 seconds twice, then gained a second, it's clear that your watch is affected by positioning.

A lot of people find that the time that is lost or gained while the watch is on the wrist can be "offset" by keeping it in the right position overnight. If, for example, your watch loses 2 seconds during the day while you are wearing it, you may find that the right overnight position will allow it to gain 2 seconds, for a net gain of 0 sec/day.

Just some food for thought.

Good luck,
