Patek Philippe Annual Calendar Moonphase Reference 5146/1G-001 in Solid 18kt White Gold with Creme Ivory White Dial and Matching 18kt White Gold Bracelet.

This exceptional Patek Philippe Annual Calendar Moonphase features a beautiful Creme Ivory White dial with applied white gold Arabic numeral hour markers at three quarter-hour positions and faceted gold baton markers at the remaining hours. Elegant luminous white gold feuille hands complement the refined dial. The day of the week is displayed at 9 o’clock, the month at 3 o’clock, and the power reserve indicator at 12 o’clock. The moonphase display and date indication are positioned at 6 o’clock, creating an elegant and balanced dial layout.

The watch is powered by the Patek Philippe Caliber 324 S IRM QA LU self-winding automatic mechanical movement. This sophisticated movement contains 36 jewels and 355 components and features a straight-line lever escapement, Patek Philippe Gyromax balance, shock absorber, self-compensating free-sprung balance spring, and 21kt gold automatic winding rotor. Operating at a frequency of 28,800 vibrations per hour, the movement is beautifully finished with rhodium plating and traditional decorative techniques. A transparent sapphire crystal exhibition caseback provides a magnificent view of the movement.

The Patek Philippe Annual Calendar represents one of the Manufacture’s most important modern complications. Introduced in 1996, the patented Annual Calendar mechanism automatically distinguishes between months containing 30 and 31 days, requiring manual calendar correction only once each year at the end of February. The Reference 5146/1G combines this remarkable mechanical achievement with the timeless sophistication of traditional Patek Philippe watchmaking.

One of the most captivating features of this timepiece is its beautiful moonphase display at 6 o’clock. The celestial indication presents the changing phases of the moon against a deep blue background, adding character and visual depth to the warm Creme Ivory White dial. The contrasting white gold Arabic numerals, faceted baton markers, and elegantly shaped hands create a highly distinctive appearance that makes this reference especially desirable among collectors.

The solid 18kt white gold case is complemented by a matching 18kt white gold bracelet featuring a concealed double folding deployant clasp. The combination of precious metal construction, refined finishing, and sophisticated calendar complications creates a remarkable luxury timepiece suitable for both formal occasions and everyday appreciation.

Now discontinued, the Patek Philippe Reference 5146/1G-001 Annual Calendar Moonphase with Power Reserve remains a highly desirable collector’s timepiece. Its distinctive Creme Ivory White dial, full white gold bracelet, sophisticated automatic movement, and beautiful calendar complications embody the exceptional craftsmanship and timeless elegance of Patek Philippe. A magnificent example of Swiss haute horlogerie and an outstanding addition to any important watch collection.
