Both watches have in common
that they are not unique pieces.
On the back it reads no 1 and not 1/1.
Mine was made in a run of 7 pieces, as a special order for a client.
So I think this one is a special order too and probably made in a really small amount, like mine.
Interesting is that there is no ruby in the crown, but a sapphire.
Great post Nico!
