Darren,
I have a 3646 v.92 (see heuerville for ref. pics)
It's back at the dealers having the chrono corrected, but should have it back next week. I'll do some rough measuring (through the crystal) for you when it's back, if that helps.

: I am currently seeking a set of dauphine hands for a first
: execution 3 reg Valjoux.72 Autavia 2446 (see my WTB listing on
: the chronotrader)
: Can anyone tell me the correct size of these hands- length/width,
: does this set of hands have a designated model name? If you
: check the OTD photo reference,

: you can see there are 2 types - fully lumed / center part lumed.
: They seem to be the same overall shape.

: Further question - do the hands from a Valjoux.92 or any other
: popular movement fit correctly onto the Valjoux.72 movement?

: Thanks for any help - Darren
