Interestingly, and you probably know this, but Sylvain let the mechanics “break free,” ie, let the mechanics be shaped by the attributes that he was looking for in a watch (72 hour power reserve, large balance, etc.), then designed the case around the misshapen movement. So, ultimately form followed the function. While there are aesthetic similarities (largely a function of a lack of asymmetric watches), the two watches started from a different place.
