PATEK PHILIPPE REGULATOR ANNUAL CALENDAR – Ref. 5235G-001 – 18k White Gold - Box & Papers 2018 - Like New

We are pleased to offer this highly distinctive and technically sophisticated Patek Philippe Regulator Ref. 5235G-001, presented in 18k white gold with its black crocodile stap and white gold pin buckle.

First introduced in 2011, the 5235G marked a bold departure from traditional Patek Philippe designs, being the first and only regulator-style wristwatch in the brand’s history. Inspired by precision regulator clocks used in watchmaking ateliers, the watch features a striking dial layout with separate sub-dials for hours and seconds — the central minute hand commanding focus, while hours and seconds are displayed in smaller registers at 12 and 6 o'clock respectively.

The 40.5mm case is crafted from solid 18k white gold, showcasing a flat, angular profile with brushed case flanks and polished bevels — a rare mix of classical elegance and sharpness. The two-tone dial, in silvery opaline and vertically satin-brushed graphite, is as mesmerizing as it is unconventional, with crisp typography and blue transfer-printed scales lending a distinctly scientific aesthetic.

At its core is the Caliber 31-260 REG QA, a micro-rotor equipped self-winding movement developed exclusively for this model. It features an annual calendar complication and pioneering silicon-based components, including the Pulsomax® escapement and Spiromax® balance spring, showcasing Patek Philippe's forward-thinking approach to haute horlogerie. 

The watch is fitted with a navy blue hand-stitched alligator strap and signed 18k white gold tang buckle, and is offered as a full set, including:

- Original Patek Philippe wooden presentation box and outer box

- Original warranty certificate, Germany 2018

- Instruction manuals

- Leather document holder

- Calendar corrector tool

- PP service invoice 02/2026 - small maintenance service in Switzerland

- Patek service pouch
