Been having some issues with an Oris and a watch repair shop and would appreciate your opinion on this.
Some weeks ago I realized I don't wear my 3-year-old Oris Coltrane enough, so two weeks ago I wound it up fully on a Monday morning and wore it to work. On Tuesday it stopped running at some point in the afternoon. I wound it up again on Wednesday morning and wore it to work again and it stopped working again on Thursday afternoon at around the same time. Having read up on the issue a bit, it looked as if the Sellita SW200-1 sometimes has issues with the rotor becoming "sticky" after a while can require a service. So on Friday afternoon I dropped it off at a watch store that is certified for repairs on a number of brands, including Oris. I told them that I felt the watch wasn't winding properly and that it may be due to a stuck rotor.
A week later on Saturday I picked up the watch, which the shop said had been repaired and tested. In the shop, I asked what the issue was and they said that it was magnetized and they demagnetized it. The watch showed no signs of running very fast in the days before I dropped it off, but I didn't press the issue.. I wore the watch out of the shop and walked home, which took about 40 minutes.
The next day on Sunday, the watch stopped working again in the afternoon.
I wrote the store and told them that in my opinion, the issue with the watch was not fixed. They disagreed, said their tests showed that it was magnetized and that I could only know for sure that it's not fixed if I wear it a full day. I could do that, however tomorrow I have some time where I could stop by at Oris's HQ in Hölstein and give them the watch for repair as I'll be in that area for unrelated business anyways - but it would cost me an extra hour of my time.
My question to you is - is the shop right and could magnetization caused the automatic winding to not work properly?
Should I stop by Oris tomorrow and drop off the watch, or should I follow the shop's advice and wear it for a day and see if it works properly now, in the assumption that the 40 minute walk on Saturday was not enough to wind the watch up fully?
And because a thread is worthless without pictures:
