When Patek Philippe introduced the reference 5140 in 2006, it marked the natural evolution of one of the manufacture’s most emblematic complications: the perpetual calendar. As successor to the legendary 3940, the 5140 maintained the same spirit of understated sophistication and technical refinement, while offering a more contemporary interpretation through its slightly larger 37.2mm case and sleeker dial design.

Crafted in platinum, the present example stands as the most visually striking of the entire lineage, featuring a mesmerizing blue sunburst dial that immediately distinguishes it from its counterparts. The metallic tone shimmers between deep navy and electric azure depending on the light, lending the watch a quiet grandeur—cool, reserved, and unmistakably modern. The elegant dauphine hands, applied white-gold indices, and discreet minute track all harmonize perfectly within the balanced tri-compax layout that has become synonymous with Patek Philippe’s perpetual calendars.
