Hi it's a 3646 Autavia 3rd execution probably around 1968-1969. Not
: sure about the hands...pic's too small for me to see.

: Dial may clean up with the right watchmaker on the job though
: discolouring of the subdials is common and can look ok. Crown
: should be signed. Bezel is correct for this model.

: I hope I'm correct though I'm sure if I'm not others will correct
: me (glad to be corrected)!

: I have the same watch...hopefully the movement is in good nick.
: That's pretty important. These are really great watches and wear
: well on the wrist being bigger than the 36mm Carrera's from the
: same era. They are also on the rise price wise...

: Good luck with the sale. Have a look at the OTD price guide.

Hello Nathan

Thank you for the feed back, as for the crown I think I have read that some of the early ones where unsigned, but I may be mistaken. No doubt some one will verify this.
