Hello, Hope someone can throw a little light on my problem. I have a 2012 model of the above with a 2500 calibre movement and a watch reference of 2123.04.12.001.002. I have it in a rapport winder most of the time, and just lately it seems to keep stopping after 3 or 4 days of being on the winder. I have tried hand winding ( around 80 turns ) but it does not seem to start the watch. I have noticed that as I wind the crown does seem to tighten up a little. but after wearing for a few days and then putting back on the winder it stops within a couple of days ? I know the manual says this model can be wound to start it up. just wondered if anyone had any observations . thanks, Janjon.
