Clous de Paris detail gives this Patek Philippe Calatrava 3796D a touch of texture, framing the white dial with the hobnail bezel collectors look for in this reference. In yellow gold, it stays true to the Calatrava ideal of formal restraint while adding just enough definition at the edge of the case. The manual movement suits that traditional character, keeping the watch intimate and deliberately simple. At 30.5mm and 7.5mm thick, it wears with the compact, slim profile that makes a classic dress watch so persuasive.
