The perpetual calendar watch often captivates watch enthusiasts with its complex mechanism, resembling a miniature computer, automatically adjusting to the correct date based on different months and days, including leap years. Watches & Wonders 2023 also includes many watches with complex functions, whether it’s Piaget’s ultra-thin perpetual calendar or Vacheron Constantin’s double-sided masterpiece, each with its own unique selling points.
Piaget Polo Ultra-Thin Perpetual Calendar Watch
Piaget has always been known for its ultra-thin movements. As early as 1960, the brand introduced the 12P movement, which pioneered the use of micro-rotor technology and became the thinnest movement in the world at that time. 50 years later, based on this, the brand launched the new 1200P movement. In 2023, Piaget once again upgraded the 1200P movement by adding a perpetual calendar function. The movement is only 4 millimeters thick and is named the 1255P movement.
This movement is first introduced in the Polo Perpetual Calendar Ultra-Thin watch, with a thickness of only 8.65 millimeters. The emerald green dial is adorned with a straight grain pattern, with subsidiary dials at 9, 12, and 3 o’clock positions, displaying the date, month (including leap years), and day of the week, while the 6 o’clock position features a moon phase display. The watch can accurately calculate the day of the week, date, and year until 2100.
Vacheron Constantin Les Cabinotier Master Loft Dual Moonphase Grand Complication Watch
The watch is equipped with a new self-made 2755 TMRCCQP manual winding movement, which consists of 774 parts and has multiple functions such as a minute repeater, perpetual calendar, precision moon phase, and star chart. The classic retrograde display function of Vacheron Constantin is also retained to display the date.
The dial design is unique, with a dual moon display in the central position. The dial is adorned with exquisite polishing details, different from the usual design. The large-sized moon phase display window is located at the core of the dial, depicting the changes in the waxing and waning of the moon observed in the northern and southern hemispheres. The background of the moon phase display window is treated with PVD, presenting a vast deep blue night sky, while the surface of the moon is cut with micrometer-level precision stainless steel, creating a sparkling effect like stardust.
