Tourbillon Retrograde Date Openface 41MM Pink Gold Slate Grey Dial

REGAL 18K PINK GOLD CHASSIS EMBELLISHED WITH AN ELITE AVANT-GARDE MULTI-PART FAÇADE

This exceptional timepiece projects absolute mechanical dominance through its refined 41mm structural framework, achieving a perfectly proportioned thickness profile of 11.07 millimeters to sit comfortably as an elite dress complication timekeeper. The entire case body, slender bezel, and historic curved stepped lugs are masterfully sculpted from solid 18K 5N Pink Gold—selected exclusively by the Maison to present a warm, opulent pink metallic luster that tracks ambient light beautifully. The surfaces display a flawless mirror-polished finish that radiates classic warmth.

Honoring the purest ancestral codes of fine watchmaking, the architectural layout perfectly preserves the stepped lugs, thin bezel, and distinctive fluted caseback track. Certified with the historic Poinçon de Genève (Hallmark of Geneva) established in 1886, this watch complies with the highest standards of provenance, quality craftsmanship, and mechanical reliability. Viewable via an anti-reflective sapphire window on both sides, the movement exposes its fine hand-crafted finishes, while satisfying a daily-resilient 3 bar (30m) water resistance behind a scratch-resistant sapphire shield.

TRIPLE-ASSEMBLED OPENFACE FAÇADE EMPOWERED BY AN EXPERT RETROGRADE BALLET

The visual soul of this creation is beautifully laid bare across its highly customized openface dial layout, meticulously assembled in three distinct parts to maximize depth of field: a transparent sapphire crystal disc, an 18K gold segment in the upper part treated in an elegant slate grey tone with hand-guilloché patterning, an 18K gold tourbillon seconds ring, and surrounded by a sleek slate grey opaline flange. The external zone features a traditional railroad minute track, flanked by applied 18K gold indices and crisp Dauphine-style hour and minute hands ensuring absolute scannability.

The technical interface is purposefully calculated to be clean and highly legible, dividing its complex astronomical metrics across perfectly balanced focal zones:

1. The Upper Arced Perimeter: Features the advanced retrograde hand-type date indicator. Tracked by a distinctive 18K gold blackened retrograde date hand tipped with a high-contrast white arrow, the mechanism instantly snaps back to day one at the turn of the month, executing a captivating kinetic sequence.
2. At 6 O’clock: Houses the majestic open tourbillon aperture carriage, engineered to negate gravity’s pull. The hand-polished bridge structure incorporates the Maltese cross outline, carrying a dedicated indicator that tracks small seconds smoothly.

MANUFACTURE CALIBER 2162 R31 ENGINE: SLATE GREY NAC TREATMENT WITH 3-DAY POWER AUTONOMY

Ensuring absolute operational precision and kinetic authority is the high-performance mechanical self-winding movement, Caliber 2162 R31, calculated, constructed, and hand-decorated entirely within Vacheron Constantin’s foundry in Geneva. Composed of 242 individual components and 30 jewels, this elite engine operates at a frequency of 18,000 vibrations per hour (2.5 Hz). To project a bold and contemporary note, the caliber structure is enhanced with an advanced chemical NAC surface treatment, yielding a dark, modern slate grey shade that contrasts beautifully against the pink gold elements.

By utilizing an advanced peripheral oscillating weight moving along the caliber rim, the engine preserves an ultra-thin profile of just 5.65mm thickness, ensuring that the manual hand-finishing on the structural components remains completely unobstructed from both sides. Furthermore, this manufacture caliber supplies an exceptional power reserve of 72 hours (3 full days of continuous rate stability), tracking time with undisputed authority.

PREMIUM GREY ALLIGATOR STRAP EMBODYING ABSOLUTE NOBILITY

To match the unique contemporary refinement of this openface Grand Complication reference, the timepiece arrives on a premium alligator leather strap executed in a rich matching grey tone, establishing a deeply sophisticated monochromatic harmony with the slate grey components while creating a powerful contrast against the pink gold chassis. Secured to the wrist by an authentic 18K pink gold triple folding security clasp shaped to echo the lines of the Maltese Cross emblem, this masterpiece commands absolute distinction in the most exclusive lifestyle circles.
