I noticed Jeff's response was his is number 48655...

: Hi Eric,
: i am surprised to hear of an Autavia down in the 46xxx range.
: My understanding was that the range started in the 48xxx as seen on
: this webpage
: http://www.onthedash.com/docs/AutaviaRegistry.html
: I can offer up 2 serial numbers for early dauphine hand model
: 2446's that dont appear in the data base.
: One is 48859 - with the lume insert hands
: Second is 49229 - a full lume hand model.

: A side note here.
: We often hear it quoted that the full lume hand models were the
: very first execution of Autavia but we also see the full lume
: 2446's in a very narrow batch from 49169 - 49229, a spread of
: only 60 in serial numbers. Clearly there are known lume insert
: examples with lower serial numbers, it begs the question - were
: the full lume hand versions really the first Autavia's offered
: for sale OR did Heuer take the cases out of sequence and use
: numbers 49169-49229 first and then return to use the earlier
: numbered cases on the lume insert modes?
: Hmmm - if only Heuer had kept the official records that Rolex/Omega
: and many others kept !

: Cheers & good luck hunting your lowest reference numbers.
