I am trying to identify the movement number for this Ulysse Nardin 8-day movement...I need to order a mainspring...I did measure it but nothing in my catalogues...thanks...

Have you checked Ranfft?

It was likely made by A. Douard. I don't know the exact designation of the caliber.

Is there an expert we can call on to differentiate between the seeming scores or permutations/cross-companies/ebauches of this company? I have talked to the Swiss about this and they just do not seem interested. Such an interesting history.
