Patek Philippe

I know the calatrava cross deployant buckle comes in various sizes that measure the width of the strap that slides through it. Most commonly I have seen 14mm. Do they make an 18mm or larger?

.

so much more common than the 16mm? thanks

why is the 14mm calatrava deployant so much more common than the 16mm? thanks

and availability - smaller watches (old collections) need smaller buckles. I assume you are talking about second market, am I right?

YG 16mm calatrava cross deployants seems to be quite rare.

since a few years and the older ones are smaller (watches, buckles ...). For me it is obviously, isn´t it?

I have previously owned mostly Rolex, Explorer II, SS Daytona, Rose Gold Ceramic Daytona (chocolate dial), and Cartier Chronograph with the Piguet movement. I recently purchased a Patek 5712G and love it. I like to customize watches to my taste, for examp... 

after all my research, unfortunately, there does not appear to be any other deployant buckle that will fit the Nautilus strap. this info came directly from AD. this is unfortunate because i think the classic cross logo would look very nice on this watch. ...
