I think its an incredibly difficult task to try & value these rare 1st execution Autavia's as its just so seldom we see them offered up for sale.
There are no shortage of fans of the big eye screwbacks & its a case of die hard fans making an all out lunge at the opportunity to own such a watch.
With that in mind we see the frantic & committed level of bidding on this 3646 - 5 serious bidders over the €12000 mark.
The missing dauphine hour & minute hands are an issue but over the years we have seen them offered for sale. Perhaps the buyer is well connected within our community & has enough solid contacts to shake a pair of hands out of someone spares box.
As Paolo states is his posting above the watch is in correct order other than the main hands. I was personally a little surprised to see it sell at over €15000 but if the buyer has the hands already OR a solid lead as to where to find a pair this could turn out to be a very good value for money buy in the future.
The sad news for many collectors out there ( myself included ) is that these eye watering high values now obtainable by the rare & significant models may actually push some of us aside as the costs become prohibitavely higher.
Has the ship of opportunity sailed ? Maybe !!!!
I cant see these early big eye Autavia's coming down in value. They have always been sought after but seem to be the forum darling at the moment.
