Sticking with the automatic caliber 12-600, the reference 2584 is a cleaner and simpler take on the idea of a self-winding Calatrava but make it thinner. Everything, the case, the bezel, and the lugs, is slim about this watch visually. On the wrist and when looking at the watch straight on, there really isn’t much going on outside of a classic Patek asthetic. But when viewed from the side, the lugs show their subtle design and, again, there is a “PP” crown telling those who know that the movement inside is extremely important.
