No matter how you slice it, the Calatrava is, and always will be, the leader of the dress watch pack. Objectively speaking, there is no other collection of time-only pieces designed as tastefully as Patek Philippe’s famed line, explaining the unparalleled high regard enjoyed by its many references. There isn’t a bad one in the bunch, but some definitely make a bigger impression than others. With its iconic spider lugs, the Ref. 1578 represents one of the watchmaker’s greatest efforts within the collection, and upon inspecting the photos of my next pick for this week’s roundup, you’ll surely understand the reason for its inclusion.
