The dial layout achieves a very balanced and vertically symmetrical aesthetic with side-by-side display windows positioned just below 12 o'clock and a sub-dial at 6 o'clock incorporating 24-hour register, moon phase and date window.

The watch is powered by the automatic Patek Philippe Calibre 26-330 S QA LU 24H with an annual calendar complication patented by Patek Philippe in 1996, which automatically accounts for months with 30 and 31 days, meaning it only requires a manual correction once a year on March 1st. The moon phase is mechanically precise enough to require adjustment only once every 122 years. The movement also delivers a power reserve of 45 hours, operating at a frequency of 28,800 vibrations per hour (4Hz), and features a central winding rotor crafted from solid 21-karat gold, stamped with the strict quality hallmarks of the Patek Philippe Seal. 

The watch come on a fully integrated stainless steel tapered bracelet with hidden butterfly deployment clasp featuring the Patek Philippe logo.  

This example dating to April 2025 is a mint condition and unworn full-set with some bracelet stickers still in place. The watch remains under manufacturer's warranty until April 2030.
