I always put the crown to the metal parts of the timegrapher. I have experience that it's not always the best if in the case and i am not putting the crown to the left. Can be that the case use a plastic spacer and the TG won't hear the sound as good.
Interesting as i have a Lemania 3600 that i changed the spring in . Used the same method as you did. Feels like it slipping . But the TG says it runs okay. Time will tell if i works as it should.
Pierre pont = Stone bridge / bridge of stone ? Places didn't really have names just descriptions of the place which then went on to become place names.
Wasn't there a fairy tale about some goats and someone living under a bridge?
Hi oldhippy my wife speaks and reads almost fluent French so I asked her to look at this and this is her interpretation.
It looks like his Name was Hugh De Pierrepont, He was resident in Neufchatel, in the lower Seine region of Upper Normandy. The de in french means of or from, so it could mean that Pierrepont was an area of Neufchatel, or that he originally came from Pierrepont. I have Identified 4 towns/villages called Pierrepont and 4 towns called Neufchatel, non are together but two are in Normandy.
In summary He was Hugh from Pierrepont
I'm curious as to what you see on the timegrapher trace to indicate loose pallet stones. The parameters look pretty good to me and the trace is pretty solid. Not trying to be critical, but curious. I work primarily on vintage movements and a trace like that would be almost orgasmic for me.
