Patek Philippe Complications 37 mm 4936J-001 bnib Yellow Gold/Diamonds White Mother of Pearl

The Patek Philippe Complications 4936J-001 is one of the most coveted dress watches in the modern Patek Philippe catalogue, uniting two of watchmaking's most poetic complications — the annual calendar and moon phase — in a 37mm 18k yellow gold case designed expressly for the discerning woman. Patek Philippe's annual calendar mechanism requires only one manual date correction per year, on March 1st, intelligently distinguishing between months of 30 and 31 days while the moon phase display tracks the lunar cycle with renowned astronomical precision. Finding this reference brand new in box is a genuinely rare opportunity that Bizak & Co. is proud to offer.

The case measures 37mm in diameter and is fashioned entirely in 18k yellow gold, a warm noble metal that Patek Philippe has mastered across generations of iconic timepieces. The round profile is finished with the understated polish and proportion that characterises Patek's Complications dress collection, while a screw-down crown speaks to the serious engineering beneath the elegant exterior. At 37mm the watch occupies that ideal middle ground: substantial enough to be easily legible on the wrist yet graceful enough for the most formal occasion.

The dial is the centrepiece of 4936J-001 and one of its most captivating attributes. White mother of pearl, quarried from natural mollusc shells, shimmers with an iridescent play of light that changes character from every angle and under every light source — no two dials are ever identical. Roman numeral hour markers in yellow gold are applied with jeweller's precision, lending a classical legibility that harmonises beautifully with the warm gold case. The annual calendar sub-dials and moon phase aperture are integrated with architectural care, ensuring that information-density never overwhelms the dial's inherent beauty.

Framing the dial is a domed yellow gold bezel set with diamonds, a detail that elevates the 4936J-001 into genuine jewellery-watch territory without ever sacrificing the horological integrity for which Patek Philippe is universally admired. The bracelet is a fine leather strap, hand-selected to complement the gold and diamond aesthetic while providing all-day wearing comfort. Together, the materials and finishing reflect the exceptional standard of Geneva Seal craftsmanship that Patek Philippe has upheld since 1839.

Powering the watch is a Patek Philippe automatic movement, the fruit of the manufacture's in-house research and development and executed to tolerances that exceed industry norms. Patek Philippe movements are renowned for long-term reliability and serviceability, meaning that a watch purchased today can be passed to the next generation in working order — a promise the brand encapsulates in its famous advertising heritage. Every movement is regulated, tested, and certified to meet the strict criteria of the Patek Philippe Seal.
