Vacheron Constantin Introduces New Traditionnelle Perpetual Calendar Ultra-Thin In 36.5mm
Vacheron Constantin has expanded the Traditionnelle collection with two new references of the Traditionnelle Perpetual Calendar Ultra-Thin, now presented in 36.50 mm cases without any gem-setting. These models bring the perpetual calendar complication into a smaller, more adaptable format suitable for various wrist sizes while preserving the technical sophistication and classical design language that define the Traditionnelle line.

Case and Design
The new watches are crafted in either white gold or pink gold and measure 36.50 mm in diameter with a thickness of 8.43 mm. Their profile reflects the signature aesthetic of the Traditionnelle family, combining a polished round case with a slim bezel and straight, finely executed lugs. A sapphire caseback reveals the movement inside. The proportions offer a balanced blend of elegance and functionality, presenting a traditional perpetual calendar in a compact and refined size.

Dial Layout and Display
The silver-toned opaline dial follows a structured and symmetrical layout to enhance readability. The month and leap year indicator is positioned at 12 o’clock, the date is shown at 3 o’clock, and the day of the week is placed at 9 o’clock. At 6 o’clock, the moon-phase display is accompanied by an indication of the age of the moon. Each sub-dial features a snailed finish that differentiates the displays, while the time is indicated by faceted Dauphine-style hour and minute hands. Applied gold hour markers contribute to the dial’s classical appearance. A railway-style minutes track runs along the periphery, reinforcing the traditional character of the watch.

Calibre 1120 QP: Ultra-Thin Automatic Perpetual Calendar Movement
Powering the new models is Vacheron Constantin’s calibre 1120 QP, an ultra-thin automatic movement that has long been a benchmark for the Maison’s perpetual calendar creations. The movement is only 4.05 mm thick and is composed of 276 individual components. It operates at a frequency of 19,800 vibrations per hour (2.75 Hz) and provides a power reserve of approximately 40 hours. In addition to hours and minutes, the calibre drives the perpetual calendar indications for the day, date, month, and leap year, as well as the moon phase and moon age. Visible through the sapphire caseback, the movement displays traditional finishing such as Côtes de Genève on the bridges. The oscillating weight is crafted in 22k gold, openworked to form the Maltese Cross emblem, and contributes to the overall refinement. The movement is also certified with the Hallmark of Geneva, underscoring its craftsmanship and precision.

Straps and Price
The white gold version is delivered on a light brown alligator leather strap, while the pink gold version is paired with a blue alligator strap. Both straps are fitted with corresponding gold pin buckles. The retail price for each model is CHF 86,500.

Summary
These new additions to the Traditionnelle Perpetual Calendar Ultra-Thin collection offer a refined and traditionally sized perpetual calendar equipped with a historically significant ultra-thin movement. By introducing the complication in a 36.5mm format without gem-setting, Vacheron Constantin broadens the appeal of the Traditionnelle line while maintaining its commitment to classical elegance and technical excellence.
