That the crown isn't screw-down
might have something to do with the fact that it's a hand-wound movement.
Not that it would be impossible to feature a screw-down crown on such a movement, but it would be unusual and a bit contradictory to the daily winding ritual.
Just my guess, I might be completely wrong.
But I imagine they've figured how to secure a 10 ATM water resistance with a simple push down crown.
Anyway, this watch looks gorgeous and I wish you a lot of pleasure with it.
Best, Emmanuel
