Just to put a close in this thread, and thanks all for your info, the watch was confirmed gen by RSC, they asked me an outrageous amount of money to replace the dial, crystal and bezel, I didn't make any changes and the daytona is now SOLD.
Unfortunately I do not have more pics of the mvt, but it was a zenith.
thanks again
I'll try that, i'll go to the watchsmith tomorrow to get it back and as soon as i get it i'll take some more pics is there any danger trying to open the case back?
