The Watch: Franck Muller has long been known as the “Master of Complications,” and the 5850 Quantième Perpétuel exemplifies why. Housed in the brand’s signature Cintrée Curvex case, this perpetual calendar displays the full measure of Muller’s technical and aesthetic vision. The 18k yellow gold case measures 32mm x 45mm, curved for ergonomic comfort and striking presence on the wrist.
The silver dial features classic Breguet numerals and blued steel hands, with a complete perpetual calendar display: day, date, month, leap year, and moonphase. This complication is designed to account automatically for the varying lengths of months and leap years, needing no correction until the year 2100.
The overall execution is both traditional in horological craft and distinctively Franck Muller in style.
Condition: Excellent condition overall. There is a small mark on the crystal near 8 o’clock, otherwise the case, dial, and movement are clean and well-preserved.
