Much of the attention around Vacheron Constantin’s SIHH outing this year was centered on the stupendous Traditionnelle Twin Beat Perpetual Calendar that it was easy to ignore the makeover some of the brand’s classic designs got this year. The color blue was injected into a few of the collections and that trend continues with the launch of the new Patrimony Perpetual Calendar Ultra-Thin, a Vacheron classic that now gets a gorgeous midnight blue dial.

This Patrimony model was first introduced in 2011

The Patrimony Perpetual Calendar Ultra-Thin has been a part of the broader Patrimony family since 2011. Not much has changed for the watch in the past eight years other than the addition of this refreshing midnight blue dial. Classic baton hands turn above a cambered dial on which the minute track is beaded with gold cabochons.

The watch is ultra slim at just 8.9 mm case height

The hour markers are both trapeze and baton-shaped. Beneath the sunburst, satin-finished dial, the lunar disc presents a matching pink gold moon set against a lapis lazuli sky. The 41 mm-diameter by 8.9 mm thick 18K pink gold case is water-resistant to 30 meters and fitted with a sapphire crystal caseback revealing the automatic movement inside.

 The watch is powered by Caliber 1120 QP

Ultra-thin Caliber 1120 QP perpetual calendar measures a mere 4.05 mm thick. Beating at a frequency of 2.75 Hz (19,800 vibrations per hour), it has an approximately 40-hour power reserve. Caliber 1120 QP drives indications of the hours, minutes and perpetual calendar featuring the day of the week in a subdial at 9 o’clock, the date in a subdial at 3 o’clock, the month and leap year on a 48-month subdial at 12 o’clock, and the moon phase at 6 o’clock.

The Vacheron Constantin Patrimony Perpetual Calendar Ultra-Thin has an easy sophistication about it. With the midnight blue dial, it is priced at $78,000 and will be available later this summer exclusively at Vacheron Constantin brand boutiques.
