I’d never actually seen the Gruen version. Thanks, Matthias! That original pic shows so much detail. For sure it’s the same caliber & same setting bits (that’s huge). But I think Matt is subtly pointing out the serial number scheme variance. Not having a Gruen to see the front plate, I guess we’ll have to wait & see if there’s a second serial number on the dial side like on Cary’s oval.

Bernd showed Cattin’s twin to this 845: I now can see both Cattin’s and Huning’s lack the case screws seen on the Gruen, and there are a couple of holes that are missing or extra.

I’m guessing the 841 & this 845 could both be top grade LeCoultre ebauches, and we’re looking for a finisher. But boy it’s fun seeing the storied brands where they are showing up! And a setting bits match lends hope to a 100 year old mystery.

I just hope others find it interesting.
