Feature Description

An homage to astronomical observation and the beauty of celestial mechanics, the new Clifton Perpetual Calendar embodies one of the most successful and fascinating complications of distinguished watchmaking. What other instrument better connects humanity with the universe? Nestled within a stunning 18K red gold case, this subtle mechanism negotiates all the particularities of the Gregorian calendar with its 31, 30 or 28-day months and the periodic return of February 29th. A truly mechanical challenge for watchmakers, the perpetual calendar is a symbol of human ingenuity for tracking the earth and its moon as they orbit within the solar system. By indicating the date, the day of the week, the month and the phases of the moon, and by automatically keeping track of the variable length of each month and the cycle of leap years, this Clifton Perpetual Calendar establishes itself within the line age of the most complicated date-tracking watches,those which do not require any date correction before the 1st of March 2100, a non leap year that appears three centuries out of four.

MECHANICAL PROWESS


Baume-et-Mercier-Clifton-10306-hightouch-back

A great classic of watchmaking complications, the perpetual calendar represents a challenge of construction and miniaturization. The programming and reproduction of celestial mechanics is the most successful of the so-called «astronomical» complications.To keep track of all the variations of the calendar, the Clifton Perpetual Calendar is thus endowed with a «mechanical memory» of 1461 days, the equivalentof four years, which animates the self-winding Vaucher 5401 movement within the watch, designed from a Dubois Depraz 5100 Module. Always with respect to the art of watchmaking, the elegant finishings of the calibre include the Côtes de Genève on the bridges and stippling on the bottom plate as well as blued steels crews. The micro-rotor, which makes it possible to pare down the movement fora case that is barely 4.2 mm thick, is decorated with the brand’s Phi symbol and asnailed décor.Ticking away at 21,600 vibrations/hour for a power reserve of 48 hours, this finely finished calibre can be admired through the sapphire crystal back of the elegant 42 mm case in 18K red gold with carefully drawn curves. Display side, the new Clifton Perpetual Calendar captivates by its simplicity: topped with a sapphire“chevée-shaped” crystal for better readability, its silvered opaline domed dial is stylish and classic, complemented by numerals and stamped indexes in 18K red gold, while the blued hands indicate the watch’s calendar functions. The date appears at 3o’clock, the days of the week at 9 o’clock while the months and the leap years appear at 12 o’clock. The timeless elegance of this Clifton Perpetual Calendar extends to its black alligator strap with a pin buckle in 18K red gold. In line with Baume & Mercier’s philosophy of offering accessible timepieces, including those which boast complex watchmaking complications, this model was designed with a care and an attention to detail worthy of the finest watchmaking.
