I think I bought it 2017...so it lasted for 8 years which is not bad I guess. It started to severly koose accurancy, sometimes suddenly stopped running and the crown was quite hard to turn when winding...so I read the signs and sent it in for a full servi...
Question: do you keep yours in a watch winder? Mine is...and I wonder if this had a 'negative' impact...resp. is the reason why it needed a service...?
