ยทI'm looking to ID the right model number of this watch so I can buy the correct balance staff.
It's a Zenith movement, 19'''. Outer diameter (including the seating flange) is 43.1mm, and the diameter at the bridge plates is 41.2mm.
There are only a couple possibilities that are a reasonably close fit to the staff I pulled out of it, I think it must be either a Ronda 3957 (fits a 19"' chemin de fer 142) or 2611 (fits the Caliber FS 19"').
The main difference between these staffs is the length, which I can't measure the length of the old staff, both pivots were broken off. I also can't measure the inter-jewel distance as the mainplate balance jewel is broken out and I have to replace that too, depending which staff I need.
