Is this a Longines cal.17.69NZ?

[morningtundra]

I’ve been trying to identify this. Is it a match for this one on Ranfft?

Yes, lots of rusty gaping holes! And the ratchet wheels in a different position! I completely missed that too!

I was going to start looking for a donor movement but not sure what I’m looking for yet. Ranfft doesn’t seem have a 15j match.

That config looks closer. But the anodized gold finish looks much more high-end.

well can tell ya it's early say 1920's or 1930's probably 30 x 30 mm is it a sub six ?

remember that movement from a dennison sub-six in a gold case got z332 in my head for some reason sure I got the link some where

Couple of notes, the older you get the more prevalence of screwed jewels as opposed to pressed in. I don't have a reference in Swiss models, but as for the US, earlier jeweled models used screwed in jewels. Lastly, early on, companies would use the same movement (base plate, bridges, etc.) and change the jewels used. I have a UN version which most folks associate with their top of the line 21 jewel movement, but it only has 15 jewels.

Not that this helps except to understand why it is harder to pin down.

All the best,
Dan

think for me showing the front as well as-the movement help to identify them ... think you have it thou so would say a version of the 12.68z then ?

I would agree that it is a version of the 12.68z. The bridges have the same look and layout and the screw holes match. it is not uncommon for a manufacturer to not plate a lower jewel movement. One way to build "value" in a higher jewel count.

Thanks!

Yes it’s a sub sec. Can’t figure out how to remove the stem so haven’t removed it from the case yet.
