Patek Philippe 5204 and 5960P Pickup

Patek Philippe Reference 5204 Split-Seconds Chronograph Perpetual Calendar

The Reference 5204 combines split-seconds chronograph functionality with perpetual calendar complications in a 40mm case format. This reference represents Patek Philippe's approach to integrating dual chronograph timing capabilities with complete calendar functions, positioning it as a grand complication within the manufacture's lineup.

The 40mm case is available in 18k white gold or rose gold with polished bezel treatment and sapphire crystal. The manual-winding Caliber R CH 27 PS QI provides 48 hours of power reserve. Dial options include silvery-gray or silvery-opaline finishes, paired with alligator leather straps. Water resistance is rated to 30 meters.

Produced from 2012 to 2019, the 5204 appeals to collectors seeking complications beyond standard chronographs or simple perpetual calendars. The split-seconds function adds timing versatility while maintaining the traditional manual-winding operation characteristic of high-end chronograph manufacture. The reference serves collectors prioritizing mechanical complexity and dual precious metal case options.

The Patek Philippe Complications reference 5960A, introduced in stainless steel, represents a significant offering within the brand's annual calendar chronograph series. This particular reference is notable for being the first annual calendar chronograph from Patek Philippe to be offered in a non-precious metal, making it a distinctive piece in the Complications collection. It combines practical complications with a robust case material, appealing to collectors seeking a blend of utility and horological complexity.

This reference features a 40.5mm stainless steel case, housing the self-winding Caliber CH 28-520 QA 24H. The movement provides a power reserve of approximately 55 hours and is visible through a sapphire crystal case back. The dial is presented in white, protected by a sapphire crystal, and the watch is water-resistant to 30 meters. The integrated stainless steel bracelet complements the case material, providing a cohesive aesthetic.

The 5960A in stainless steel holds a specific position for collectors due to its material choice and the integrated bracelet, differentiating it from its precious metal counterparts. Its combination of an annual calendar and chronograph functions, along with the 24-hour indication, makes it a highly functional and mechanically interesting timepiece. The special hand set and case back decoration mentioned for this specific 5960A further emphasize its unique attributes within the production run.
