i am starting to put up some service manual on my site for anyone/watchmaker out there who needs help with movements heuer used over the years. This is just the start, but i have started off with athe valjoux 23 service manual which has so far never been available on the web. it has the full parts numbers list (which is also compatible with the valjoux 72) this is very important in helping findind correct parts for our beloved valjoux heartbeats. a few watchparts stores still carry parts for these so these numbers are very helpful.
please enjoy, if not now some time when its needed.
