It is a 10 size. I measured twice, to be sure. Very feasible that it at least shares parts with the 35. 60 is a new number for me—would seem to fit the time.

Edit: And now that you mention it, I see 60 in the interchangeability tables as a 17L (10 size) movement. No jewel count listed. May have a match!

Having all seen the recently-sold 7J version of this family (Primo branded, link shared by Liz), it’s clear there are some unknowns/undocumented ones floating out there.


My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more
