Vacheron Constantin Patrimony Perpetual Calendar Pink Gold / Blue

The Vacheron Constantin Patrimony Perpetual Calendar Ultra-Thin, reference 43175/000R-B519, was introduced in 2019. This elegant timepiece features a 41mm 18K pink gold case with a slim profile of 8. 91mm, embodying the minimalist aesthetics of the Patrimony collection. The midnight blue dial, adorned with a sunburst satin finish, showcases applied pink gold hour markers and bi-faceted baton-type hands. The perpetual calendar complication displays day, date, month, leap year, and moon phase, with the moon phase indicator featuring a champlevé enamel sky and two hand-finished moons. At its heart lies the in-house caliber 1120 QP, an ultra-thin self-winding movement measuring just 4. 05mm in thickness, operating at 19, 800 vibrations per hour, and offering a power reserve of approximately 40 hours. The watch is water-resistant up to 30 meters, ensuring practicality alongside its refined aesthetics. It is presented on a dark blue alligator leather strap, secured by an 18K pink gold folding clasp, epitomizing comfort and style. The transparent sapphire crystal case back allows for admiration of the movement's intricate finishing, highlighting Vacheron Constantin's dedication to haute horlogerie.
