Lot Essay

Unveiled at Baselworld 2012, Reference 5235 stands out as a innovative model in Patek Philippe’s lineage. At its core is the Caliber 31-260 REG QA, where "Régulateur Quantième Annuel" signifies its unique regulator-style display combined with an annual calendar. This marks the first time Patek Philippe has incorporated a regulator dial into an annual calendar wristwatch, reinforcing the brand’s commitment to precision and innovation.

Unlike conventional timepieces, the 5235 features non-coaxial hour and minute hands, meaning they do not share the central pinion but are independently positioned—enhancing legibility and accuracy. Among collectors, this reference is widely regarded as one of the most significant technical advancements in Patek Philippe’s modern history.
