Debuting today amongst a handful of other pre-SIHH releases, the effortlessly elegant Vacheron Constantin Patrimony Moon Phase and Retrograde Date stands out with its smooth combination of two prized complications. The timepiece comes in either a pink or white gold case and features a distinctive moonphase complication against a star-studded dial design. The extremely accurate moonphase display requires just a single, one-day correction every 122 years. The upper half of the dial has an attractive, minimalistic retrograde date display. All adjustments, including for the complications, are easily applied via the crown. This user-friendliness is part of the new Manufacture Vacheron Constantin Caliber R31L movement that contains a 40-hour power reserve and can be viewed through the transparent sapphire crystal caseback. The price for both models is set at $39,500.
