M MadMicIt was offical omega service. The range is 0/5s. It actually did around 8s in the beginning and then settled at sligtly over 5s. I was told it was magnetism, they de-magnetized (if that is the word) and should be around +3s according their meassurement (can’t confirm that yet).
Please read up on how the accuracy is checked/ calculated. Your was likely still within spec. Normally magnetized watches can be off by minutes/ day.
M MadMicI have seen the technicality behind measurements, which is interesting and import output I take from it is claimed accuracy over 1day. Over last 3 weeks I was tracking around 5-6s difference. After yesterday check, I can see today 3-4s. Obviously the measurements are not super accurate from my side (I basically compare to some onlineclock). I don’t know exactly what they did but I see 2s improvement in accuracy and I was told it was magnetic field. Being those my first automatic watches, I cannot add much to what the service told me. They basicaly suggested, that despite the movement is resistant to magnetic fields, I should be careful leaving it close to magnetic fields otherwise the accuracy could be still impacted.

Sometimes the movement will calm down a bit over time. Also, from experience I try to leave the time between checking more rather than less. The more often you check the greater chance of difference due to our own incorrect readings.
I check mine probably once every 2 weeks or so now. 3 secs a day is no worries whatsoever as far as I am concerned. In fact mine lose time on my winder and gain slightly on the wrist so net is ok.
So the accuracy was checked in all the different required positions? (6 positions are required, at both 100% and 33% reserve)
BTW, did you know you can check the Omega testing results for your specific watch here?: https://www.omegawatches.com/en-us/...er-chronometer-certification/#test_METAS/home
M MadMicI honestly don’t know what check they did. My expectation is that wearing the watches daily for around 12h, putting them off during night and exposing to any extreme situations, it should be in the 0/5s tolerance. I spent around 10min in the service center so not sure how much they could do. As far as it will remain within the tolerance, I am not planning to go back there .
