Thanks Emmanuel,
This looks like a stunning watch and the movement is simply gorgeous. Thanks for sharing the pictures with us!
I find it very odd that the timing results that come with the watch have the incorrect lift angle listed and therefor incorrect amplitude readings. What I mean is, the lift angle listed on the upper right of the timing sheets says 51 degrees, which is the normal "default" value of most timing machines. The lift angle input by the operator when taking the readings determines what the amplitude readings will be to a large extent, and given that amplitude readings of 347 degrees are a complete impossibility, it's clear that the operator did not set the timing machine's lift angle correctly. This seems very odd for someone presumably performing QC at the factory, especially given that the timing results were actually included with the watch.
By the way, if you want to keep all the original documentation intact, you should make a scan or a copy of the timing results to save, since they are printed on a thermal printer and will fade over time.
Enjoy your watch, it's a beauty!
