Actually the reverso with the '1931' dial has already been re-edited (in its original size though) 30 years ago
So, that makes this 'tribute' the first re-edition of a re-edition
Original re-edition:
To me, there's nothing like the original... (note: the non-luminous dial on this version)
But I must say that this new 'tribute' seems very appealing in this slim format !
(However, I would have once again saved the 'ultrathin' name for a genuine ultrathin watch though, but marketing is marketing, and there has been already so many different 'grande' sizes that it becomes hard to name a new format these days)
Let's see it in the flesh, but I think I am ready to liket it ! (though I think it will be a bit big for me still)
