I the previous post I shared some pictures of the new 5170J. I was also curious to see the skeletonised Calatrava 5180/1. The blue border that can be seen on official photos is gone. This color was apparently too difficult to produce. Technically it is beautiful and made with a lot of fine detailing. The caliber looks quite harmonic. The pictures are not so good technically, but they may give you a feeling.

The Patek perpetuals are always nice to look at. Here you can see all.
