Introduced in 2005, the reference 5250 in white gold marked the debut of the Advanced Research limited edition series. Patek Philippe revolutionized design with this model by incorporating a pioneering silicon-based escape wheel into a Swiss lever escapement, paired with an annual calendar movement, the caliber 315 S IRM QA LU SI. The Advanced Research department was established to exclusively explore and develop new technologies and materials, highlighting the company's ongoing dedication to innovation in horology. Limited to just 100 pieces, in very good condition and including its full suite of accessories, reference 5250 is a prized addition for collectors of the Advanced Research series.
