When Jeff posted his scan day idea of favourites then my first
thought was this watch as it is my current favourite:

But then I reread the scan day definition more carefully and I had to
reconsider. I love the Lemania Silverstone but it is not really a true
Heuer classic, more a minor model (though a fantastic minor model).
Then I thought of this one, as it is really THE classic Heuer:

But I am
not sure it would be the only Heuer I would keep as it is not my favourite Monaco (BTW the ugly strap is my mistake, also sorry about the useless photog with the shadow of the crystal). So I thought maybe I should go for what I consider to be the best looking Heuer in a balance of functionality and “beauty”:

But then
I reread the criteria again very carefully (it was drafted by a lawyer) and it
specified your choice would be your only Heuer. The 2446 bezel is too delicate
to allow everyday wearing, and if I have to wear a Heuer everyday (I
do) it would have to be something more robust. So in the end my final
choice is this one:

Funny that it ended on this one as my first ever pic posted to OtD (via
Jeff) was the burgundy Silverstone, I think it was more than two years ago. I think the scan day was called “your favourite Heuer”.
