Ok, so I figured out not to mess with those nuts, for aircraft clocks, you go in through the FRONT. Removing the glass face, etc.

This is something I'm curious about, what does "F...S" mean? (see attachment)

 

Fast / Slow. It's to regulate the watch.

Regulation in a nutshell: Longer hairspring length = slower oscillation, watch slower, shorter hairspring = faster oscillation, watch runs faster

 

I have one of these too (but mine's a Waltham). It's friggin AWESOME!

Just curious, why are you taking it apart? Has it been serviced? I got mine from a friend who's father flew the B-17D bomber it came out of in WWII. Mine will only run when upright. My watchmaker says it's from years of running without lubrication (I just got it last year), the pivot is misshapen. :roll:. But it runs now, and it's the coolest desk clock I've ever seen....

 

Cool project. And Bleh, I always love seeing yours. SENSATIONAL!

 

Thanks, man! :-!

I finally got a UV LED to charge my lume, and I shined it on this baby the other day. She glowed orange like a fire b-)! Too bad the lume doesn't even last a full second. :roll:
