It's not just the case that's not original.  I agree that the bezel is aftermarket; my guess is Yuki, rather than DW, due to the spacing of the '110' and the overall poor quality of the printing. 

 

I also have doubts about the movement.  Take a look at the chronograph bridge: The engravings look off and the countersinking around the rubies is noticeably shallow.  Now look at the balance bridge: I don't think Rolex ever used an Incabloc shock absorber on its Daytona movements (but please correct me if I'm mistaken).  There's also a screw going through the middle of the coupling-clutch mount, which -as far as I know- you only see on non-Rolex Valjoux 72s.

I agree, the movement is not right.

The chronograph pivoted detent bridge (the 'L' shaped bridge at 7-8 o'clock) is an early one w/ a screw in it- after the 6234, Rolex used the newer pivoted detent bridge w/o the screw.

This may be what LHOOQ refers to as the coupling clutch mount.

M, I think I need an illustrated glossary of movement parts!  I referred to that chevron-shaped bridge as a mount, because the entire assembly shows up as "#8080 - Coupling clutch, mounted" on Valjoux 23/72 manuals:

ceejay: Thanks for the info about Incabloc.  I didn't know about the naming requirement.

Looks like the watch is gone now.

 

Yep, M, we are talking about the same part. My terminology comes out of the 1949 Assembl-O-Graf Manual- whereas Valjoux does refer to it as the coupling clutch, mounted- the whole assembly.
