03. Patek Philippe Calatrava
Patek knows that the core design of this watch has been copied many times. Even by high-end competitors. So why buy the Calatrava? There are reasons above and beyond the Patek Philippe name on the dial. A good reason is the movement and the detailing. Oh, and there is the new caseback. Patek Philippe apparently spent a few years developing and perfecting an “invisible” hinged case back for the 5227.
Hinged case backs are vestiges from pocket watches designed to protect movements. On a Patek Philippe wristwatch, they are about style, and offering a place for personalization on a watch as well as retaining the ability to view the movement. You should like Patek Philippe for the movement so it is worth being able to see it.
