Perpetual Calendar Ultra-Thin 36.5MM White Gold 270TH Anniversary Limited Edition

REGAL 18K WHITE GOLD CHASSIS ARCHITECTURED WITHIN A HISTORIC COMMEMORATIVE BLUEPRINT

This limited-edition masterpiece projects absolute dominance through its refined 36.5mm multi-layered structural framework, achieving an ultra-slim thickness profile of just 8.43 millimeters to sit flawlessly flush as an elite dress complication. The entire case body, slender bezel, and curved stepped lugs are masterfully sculpted from solid 18K White Gold (750/1000), displaying a flawless mirror-polished surface finish that radiates a majestic white metallic luster.

Commemorating nearly three centuries of undisputed watchmaking authority, the architectural layout honors the purest ancestral design codes of the collection, preserving the stepped lugs, thin bezel, and distinctive fluted caseback. Certified with the historic Poinçon de Genève (Hallmark of Geneva) established in 1886, this watch complies with the highest standards of provenance, decorative refinement, and mechanical reliability. Viewable via an anti-reflective sapphire window on the transparent caseback, the movement exposes its fine hand-crafted finishes, while the secure housing provides a daily-resilient 3 bar (30m) water resistance.

PRISTINE SILVER-TONED PORT FAÇADE EMBELLISHED WITH BI-COLOR PINK GOLD ACCENTS

The visual soul of this celebratory creation is beautifully laid bare across its highly refined, silver-toned dial interface, calculated specifically to honor Vacheron Constantin’s rich heritage. The external perimeter zone features a classic circular railway-track minute circle. In a rare and highly collectible structural twist executed specifically for this 270th anniversary milestone, the central bi-faceted Dauphine-type hour and minute hands, applied indices, and all calendar sub-dial pointer hands are sculpted from solid 18K 5N Pink Gold, creating a powerful, vương giả contrast that shifts dynamically under lighting.

The technical interface is purposefully calculated to be clean and highly scannable, dividing its complex celestial calendar metrics across four dedicated sub-registers:

1. At 3 O’clock: Tracks the progressive Month day countdown via a pink gold hand.
2. At 9 O’clock: Tracks the current Day of the week via a pink gold hand.
3. At 12 O’clock: Displays a highly advanced counter tracking both the 12 Months and the Leap Year cycle across a 48-month display grid.
4. At 6 O’clock: Houses an astronomical Precision Moon Phase display featuring a star-studded night sky backing two polished gold moons to add magnificent structural depth.

MANUFACTURE CALIBER 1120 QP AUTOMATIC CORE: UNCOMPROMISED MECHANICS UNTIL 2100

Ensuring absolute operational precision and authority is the high-performance mechanical self-winding movement, Caliber 1120 QP, calculated, constructed, and hand-decorated entirely within Vacheron Constantin’s foundry in Geneva. Measuring an incredible diameter scale of 29.6mm and an ultra-thin thickness profile of just 4.05 millimeters, this high-complication engine consists of 276 individual components and 36 jewels, operating at a frequency of 19,800 vibrations per hour (2.75 Hz) while supplying a trusted 40-hour power reserve.

This caliber features a sophisticated “mechanical memory” that automatically calculates the varying day lengths of every month—seamlessly adjusting for 28, 30, and 31-day intervals, as well as the recurring 29-day February leap year shift—requiring absolute zero manual intervention until the year 2100. The openworked caseback framework reveals an incredible anthology of haute horlogerie decorative details, including hand-polished chamfers, delicate perlage, and a beautifully hand-finished oscillating weight.

PREMIUM LIGHT BROWN ALLIGATOR STRAP EMBODYING ABSOLUTE NOBILITY

To honor the historic rarity of this 270th anniversary reference, the timepiece arrives on a premium alligator leather strap executed in a rich light brown tone, matching the warm pink gold dial elements beautifully while establishing a highly sophisticated contrast against the white gold chassis. Secured to the wrist by an authentic 18K white gold Ardillon pin buckle shaped to echo the lines of the Maltese Cross emblem, this masterpiece commands a versatile and deeply prestigious presence in the most exclusive lifestyle circles.
