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
