The 885 is another common one out of the caliber stable. I've one on the bench and thought I should take some images. Afire has this post on his very fine watch, which I think is the only other one that clearly IDs what the movement is. An ebauche finished by/for Gruen from FHF. However, Afire state 324, Ranfft indicates the cal 1146 by FHF. There is a clear stamping with the FHF mark.

For those working on restoring the 885 there is this post on issues with the staffs
Cousins has the mainsprings as 1.45 x 0.11 x 280 x 9 (Part #GR3981) and Borel has these as 1.40-.10-320 9 (Part # MS-511M). Both are in white alloy.
Gruen (1947 Horological Manual) listed the size as 1.45 x .11 x .280 but this is for a blued steel.


All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me

Huh. I must have gotten that from somewhere. There was this discussion in which the 885 and FHF 324 come up as allegedly having some interchangeability.

And a quick google of FHF find mention of the FHF 324 being the base for the Bulova 10AN, and from the bridge side, you can see a family resemblance. I googled 10AN set lever, and it certainly has more than a passing similarity to the 885 set lever.

I would say there's some connection.

The base of this movement isnt the FHF 1146  mentioned by Rannft. The stem doesnt fit.

Another example (with uncommon swirlies on the balance cock).

And a strange G next to the 885.
