I am trying to find the movement number of this Ulysses Nardin -8 Day so that I may order a mainspring....any help would be most appreciated....Thanks...

Why don't you take the barrel out and look at the m/spring and measure that. You should also make sure the teeth on the barrel and train wheels are in good condition. Look at the inside of the barrel and make sure a new spring will hold, no good getting a new spring if in side the barrel is worn, the end of the spring might not stay attached. I will have a look in my Bestfit books and see what I can find.

Generale Ressorts lists one 2.60x 0.18x 460, reference number 6772. Also one the same but 480 long ref 6773. Either should work fine. Pretty sure Cousins sells GR reference springs. If they are out of stock you can drop the height to 2.50 no problem, that would be a reference 6667 2.50x 0.18x 460.
