After three visits getting my watch serviced and then fixing some issues resulting from that I seem to have ended up with a watch that appears to keep very good time. I've now worked out why that is, after a visit to the servicing people this week (just to play with their accuracy measuring machine). It gains around 13s/day Face up, Face down and Crown down but loses about 13s/day with Crown up, which has been the way I've tended to leave it when I'm not wearing it, hence the accuracy has been averaging out...
BTW does anyone know how good the assorted numbers here are (Amplitude, Beat Error and Lift Angle) or what they mean?
Here are images for the four orientations plus a view of the measuring machine complete with my watch.

P.S. See here for a (IMHO) nice pic of my watch... https://forums.watchuseek.com/f23/rol...n-1079543.html
