because it is really hard.
From a visual point of view, they all look great.
I love the Classic and the Montre Ecole a lot and especially the Classic fits like a glove
on my 18cm wrist.
For me, the Square was too clumsy and not really comfy on my wrist,
while the Classic I don't feel at all.
That's why I said, take enough time for your decision, every wrist is different,
even when it has the same size.
