Here is the only observed “Factory V”-stamped caliber family. The forum previously confirmed “Factory V” as Lavina, who also supplied the 740/750 716, & 720 pocket caliber families, among other cals.
Production Dates: ca1919-22 (all “Guild” & pre-1922 tariff stamps for adjustments)
Maker/Finisher: The curious thing is, the 850s are not in-house Lavina movements. They have no Lavina serial numbers on the dial side—just a letter + 2-3 digit number code. Yep, these were supplied by Marc Favre (like the early V7s from this time) & finished by Lavina. The finger bridges may be unique to Lavina.
Identification: All variants are stamped “850” in tiny font between bridges, but this is hard to see in seller pics. One of Mike’s books shows a “Factory V”-stamped movement, mislabeling it as a cal 740. It is actually an 850. They're the same size & have similar bridges, but the click location is one easy differentiator without removing the dial: the 850 family clicks are on the opposite side of the wheel vs 740/750 family.
Variants: (all stamped “850”)
15J, 3ADJ: 850 —> “Factory V” stamp
17J, 3-5ADJ: 852
19J, 4-5ADJ: 854
