Tony (aperna) shares his Patek Philippe Complications Annual Calendar Regulator Ref. 5235, a timepiece that continues to captivate collectors with its distinctive design and horological significance. This article delves into the unique attributes of the Ref. 5235, exploring why it holds a special place in the Patek Philippe catalog and among enthusiasts.
The Patek Philippe reference 5235 Annual Calendar Regulator introduced a distinctive display format to the brand's annual calendar complication. This model features a regulator-style dial, separating the hours, minutes, and seconds into distinct subdials. The central hand indicates minutes, while the hours are displayed in a subdial at 12 o'clock and the running seconds in a subdial at 6 o'clock. This layout provides a clear, uncluttered presentation of time and calendar information, distinguishing it from other annual calendar offerings.
The watch is housed in an 18k white gold case measuring 40.5 mm in diameter and 10 mm in thickness. It is powered by the self-winding caliber 31-260 REG QA, a movement specifically developed for this regulator display. This movement provides a power reserve ranging from 38 to 48 hours. The watch is fitted with a sapphire crystal on both the front and an exhibition case back, offering a view of the movement. It is water resistant to 30 meters.
First appearing in 2011, the 5235 appeals to collectors seeking a Patek Philippe annual calendar with a unique aesthetic. The regulator display, while historically rooted, offers a contemporary interpretation within the brand's complicated watch lineup. Its production run has seen it offered primarily in this white gold configuration, making it a consistent and recognizable piece for those who appreciate its specific technical and design characteristics.
And exactly where it belongs: on the wrist of a gentleman! Best, Emmanuel
