vintage daytona

Is it true that with a professional franken build by the pro's (J & W) can they transform The valjaux so the bottom subdial works? this is on a vintage 37mm daytona conversion? 6263 and 6265. I dont want to pay alot of money and have a static needle at 6 oclock.

Jewelry and Watch uses the Valjoux 72 movement. This is a tri-compax movement, the same as used in the original Rolex vintage Daytonas. All three subdials are functional.

Just to add to what Alligoat already said, there are 2 types of chronographs -- bi-compax & tri-compax. An example of a bi-compax chronograph is the Valjoux 23, which has 2 subdials - running seconds and a chronograph minute counter. An example of a tri-compax chronograph is the Valjoux 72 (which is the base movement used in vintage Rolex 66xx series Daytonas & many other vintage watches), which has 3 subdials - running seconds, a chronograph minute counter & a chronograph hour counter.

The most accurate franken-tonas are powered by the V72, but you can produce a visually similar watch using a slightly less expensive (and dimensionally similar) V23 with the hour subdial 'frozen' at its normal (off) 12 o'clock position on the dial since the V23 does not have a working hour counter.

Most reasonably-priced vintage Daytona reps ($200-$350) are powered by any number of modern bi-compax or tri-compax movements. These vary in their functionality & visual accuracy since most of these movements have symmetrical pusher arrangements, which are inaccurate for the vintage gen Daytona models
