Patek Philippe Annual Calendar Moon Phase 4947/1A
The Patek Philippe Annual Calendar Moon Phase Ref. 4947/1A-001 is a rare and versatile expression of the Manufacture’s signature complication, presented in a 38mm stainless steel case measuring 11mm in thickness and paired with an integrated five-row polished steel bracelet—a configuration that brings Patek Philippe’s patented annual calendar into the realm of everyday luxury . The midnight blue dial features a distinctive “shantung” finish, achieved through intersecting vertical and horizontal satin brushing that gives the surface an almost fabric-like texture, shifting from deep navy to brighter blue depending on the light . White gold applied Arabic numerals and leaf-shaped hands with white luminescent coating ensure exceptional legibility, while the annual calendar displays the day and month via hands in recessed sub-dials at 9 and 3 o’clock respectively, with the date in an aperture at 6 o’clock alongside a high-precision moon phase that requires correction only once every 122 years . At its heart beats the in-house automatic Calibre 26-330 S QA LU, a movement comprising 319 parts and 34 jewels that operates at 28,800 vibrations per hour (4 Hz) and delivers a power reserve of 35 to 45 hours, equipped with a 21K gold central rotor, Gyromax® balance, and Spiromax® balance spring, all bearing the prestigious Patek Philippe Seal . The patented annual calendar mechanism, invented by Patek Philippe in 1996, automatically accounts for months of 30 and 31 days and requires only one manual correction per year at the end of February . The watch is secured by a steel fold-over clasp with four independent catches for enhanced security . With 30 meters of water resistance and a sapphire crystal case back revealing the meticulously finished movement, this reference represents a rare opportunity to acquire a complicated Patek Philippe in stainless steel—a combination that has become increasingly sought after for its blend of horological substance, everyday wearability, and understated elegance .
