Movement identification


Question

Hi

I got this watch in a job lot but I’ve been unable to identify the movement. The only numbers are 411.7 on the plate and 7 under the balance. I like the look of the watch so would like to repair it. Any help identifying the movement would be appreciated.

An opinion on the dial would also be appreciated, the crown and lettering look ok to me but I’m certainly no expert. There are service dates on the dial and case but I can only really make out one which is in 1944.

thanks

To narrow down your search one should start by looking at the keyless work, it has a strong resemblance with an AS 340, I would think this is a version of a movement in that family with a slightly modified train bridge.

Great call HSL! The ranfft site lists a number of calibres in this family, although none have the same train bridge. 
 

I believe Rolex and Omega used AS movements. Do you know if there is a list of these?

As said before your trainbridge is modified but the one doing it left the holes for the original bridges. I would not think it was factory done then the watchmaker would have thought about a detail like that and covered them up, I know I would.
The escape wheel is not in place so that adds to the different look to.

In the 20's - 30's there were lots of experiments going on, the only AS movement I noticed being used was the AS340 in a ROLEX Marconi jump hour, there are probably more of them but haven't seen some official list.
Here is a site with cool quirky watches like the Rolex Marconi.
