Interesting observation on these buckles
I personally prefer the simplicity of the Chevron style deployant buckle. And unfortunately I have experienced a problem already mentioned with the Calatrava style--when a friend tried on one of my watches with the Calatrava, he pushed right in the center of the cross to engage the buckle, and it collapsed in centrally, the normal convex curve of the cross became concave.
Note that Patek has discontinued the Chevron style deployant, and if you send in your Chevron they will replace with a Calatrava at no charge, as I understand. Reportedly there have been instances of the strap slipping out of the Chevron, and down goes the watch. The Calatrava does have more points of contact with the strap, and some comparison pics of this aspect would also be interesting. Unfortunately the Chevron is becoming harder and harder to find.
