Estimate: € 50,000 –⁠ 100,000

Patek Philippe’s innovation in the world of horology is exemplified in their introduction of the annual calendar complication in 1996. This ingenious mechanism required just one adjustment per year, combining both simplicity and technical sophistication. Over the years, this creation has evolved into a cornerstone of the brand’s collection. The Nautilus reference 5726, first introduced in 2010, marked another significant leap for the model, housing the self-winding Caliber 324 and expanding the iconic Nautilus family with the refined complication of the annual calendar. In 2012, the reference was updated with a striking white dial that featured bold black surrounds around the hour markers, creating a high-contrast aesthetic that immediately set it apart from its predecessors. This iteration became a symbol of Patek Philippe’s blend of elegance and practicality, offering not only an annual calendar but also a moonphase complication, all within the distinctive Nautilus case. The present example of the reference 5726, featuring the scarce and sought-after white dial, is presented in excellent condition. The sleek steel case, complemented by a robust yet sophisticated bracelet, highlights the perfect marriage of Patek Philippe’s signature design and cutting-edge horological innovation. With the discontinuation of earlier iterations in 2019, this particular configuration has become highly coveted among collectors, who regard it as a rare and timeless example of the brand’s technical prowess and aesthetic mastery.
