Just wondering. I am in the process of regulating my serviced Accutrons that still seem to be off more than the + or - 2 sec/day factory spec. Don't necessarily expect to get that close but I'll try. It is my feeling that many, if not most, of the watchmakers don't take the time to regulate these watches to factory specs. The ones I have purchased from and had serviced by the guy in Bulgaria have been very accurate but there is even variation among those. Two others serviced by a local watchmaker are not regulated quite as closely. The guy in Bulgaria regulates them to +2 secs/day and places them on an automatic watch winder to simulate wrist movement and the everyday shocks/bumps our watches are subjected to.
