Patek Philippe Perpetual Calendar Retrograde — USD 61,900

The Calatrava reference 5496P-015 distinguishes itself within the Calatrava collection by incorporating a retrograde perpetual calendar complication in a platinum case. This specific iteration features a dial with rose gold applied numeral date markers, which is an unusual detail for the model and contributes to its distinct visual character. It represents a more technically complex offering within the traditionally time-only or simpler complication Calatrava range, appealing to collectors seeking both classic aesthetics and advanced horological function. This reference is housed in a 39.5 mm platinum case, noted for its comfortable wear and relatively thin profile, approximately 11.2 mm thick. The watch is powered by a self-winding mechanical movement, visible through a sapphire crystal case back, with an additional solid platinum case back provided. The dial is protected by a sapphire crystal, ensuring clarity and scratch resistance. For collectors, the 5496P-015 offers a combination of a highly regarded complication and a precious metal case, presented in a design that maintains the Calatrava's understated elegance. Its relative scarcity and the specific dial configuration with rose gold appliqués make it a point of interest for those appreciating subtle variations and technical sophistication within established lines. The inclusion of a platinum deployant clasp and a winding box further enhances its appeal as a complete collector's item.
