I called RGM for an estimate on servicing a 5-year old Sinn 656. Of course they told me "we have to see it first" which is understandable. When I pressed them a bit they said that typical overhauls for that watch are $350-$400.
Does anyone have experience with using other service centers that are not factory authorized for servicing their watches. What's the price range you've encountered? Any workmanship problems?
The 656 uses a 2824 movement. Like all Sinns it's Top grade. I'm a bit unsettled by the knowledge that a replacement movement could probably be purchased for less than the cost of servicing an old one. I love my mechanical watches but at some point owning a quality mechanical watch seems like an extravagance that I don't need. (If only the quartz watches weren't all so ugly....jump.....jump....jump.)
