The Patek Philippe reference 4947 is one of the manufacture's most elegant Annual Calendar models, combining refined Calatrava-inspired styling with one of Patek Philippe's most practical and celebrated complications. Introduced in 2018, the 4947 is powered by the automatic Calibre 324 S QA LU, featuring Patek Philippe's patented Annual Calendar, which automatically differentiates between 30 and 31-day months and requires correction only once each year at the end of February. Its beautifully balanced dial displays the day, date and month through three apertures, complemented by a moon phase and 24-hour indication at 6 o'clock, creating a harmonious and highly legible layout. The watch is distinguished by its beautifully guilloché-patterned case band and polished bezel, adding a refined decorative element while preserving the timeless elegance of the Calatrava collection. Produced in rose gold and white gold, with a variety of dial colours throughout its production, the 4947 has become one of Patek Philippe's most admired contemporary Annual Calendar references, celebrated for its graceful proportions, technical sophistication and seamless combination of everyday practicality with classical design.
