    No, Rolex never used an ETA Valjoux 7750, but they used a Valjoux 72 on the Daytona

    Tudor used the 7750 in the Big Blocks & Prince Dates.

    They've used movements that were named Valjoux but (as the guys above mentioned) never the 7750

    Through the 60's and 70's the Valjoux in the Daytona was either a 72B, 722/1, or a 727

    I think this is accurate tho someone else can confirm, in Daytona models before 2000 that used either the valjoux or the modified zenith movement the running seconds dial was at the 9 o'clock position, after 2000 and when Rolex used their own in house movement the position of the running seconds moved to the 6 o'clock position, so you could easily tell visually whether the movement was in house or prior.

    I don't know about that, but one way you can tell is that the Zenith-powered watches are twice the price.

    Oh and the 9 and 3 subdials on the Zenith are exactly on the horizontal. Rolex's (sorry, Aegler's :)) movement lifts them up by a few degrees.

    I noticed that the rolex Valjoux 72 costs more than the rolex 4537, is it?
