Patek Philippe Complications Self-winding 5905R
Complications Self-winding 5905R Annual Calendar Flyback Chronograph in Sunburst Blue is a timepiece that has cemented its place in the brand’s lineup, offering a unique combination of complications that has garnered much attention since its initial release in 2015. The watch seamlessly marries the annual calendar and flyback chronograph, drawing inspiration from two other notable references in the Patek Philippe family: the 5960 and the 5205, hence the “59” and “05” in its reference number.

Patek Philippe’s innovation
The annual calendar complication is a practical solution that falls between a standard calendar and the highly intricate perpetual calendar. Unlike a perpetual calendar, which accounts for leap years and the varying lengths of months, the annual calendar simplifies the task by considering only the months with 30 and 31 days.
As a testament to Patek Philippe’s innovation, they introduced the annual calendar mechanism in 1996, recognizing that for most wearers, this level of calendrical complexity is more than sufficient. The annual calendar has since become one of Patek Philippe’s most successful releases.

Design and Materials Complications Self-winding
The layout of the Patek Philippe 5905R is iconic, featuring three apertures at 12 o’clock for day, date, and month indications. Additionally, there’s a sub-dial at 6 o’clock that displays a 24-hour clock and the moon phase.
The choice of dial color has been a significant trend in the watch industry, and Patek Philippe opted for a classic and timeless combination: rose-gold paired with a captivating sunburst blue dial. This pairing recalls a previous model, the 5396R, known for its elegance and style.

Movement and Accuracy
The sunburst blue dial is adorned with rose-gold ingot indices, each featuring luminescent plots within the minute scale. Dauphine hands, also coated with SuperLuminova, further enhance visibility.
The dial is thoughtfully segmented, with concentric circles distinguishing the graduated minute scale and the hour markers and calendar apertures, giving the watch a vintage sector dial appearance. The 60-minute chronograph register is positioned at 6 o’clock, a nod to the watch’s chronograph functionality, although it’s unlikely to be extensively used on such an elegant timepiece.

Price and Value
Apart from the dial and case material, the Patek Philippe 5905R remains faithful to its standard configuration. It is equipped with the self-winding calibre CH 28-520 QA 24H, neatly housed in a 42mm rose-gold case inspired by the Calatrava design.
The rotor, now fashioned in 21k gold, complements the circular dressage finish found on the movement, proudly bearing the Patek Philippe Seal, a testament to the brand’s unwavering commitment to quality and craftsmanship.
