Tourbillon Chronograph Collection Excellence Platine 42.5MM Limited Edition

REGAL 950 PLATINUM CHASSIS ARCHITECTURED WITHIN A HISTORIC 50-PIECE EXCELLENCE PLATINE BLUEPRINT

This ultra-rare limited-edition masterpiece projects absolute horological dominance through its refined 42.5mm multi-layered structural framework, achieving a perfectly balanced thickness profile of 11.7 millimeters to sit comfortably as an elite Grand Complication dress timekeeper. Following the strict rules of the historic “Collection Excellence Platine,” the entire case body, slender bezel, stepped lugs, and the winding crown (with an integrated single-push chronograph button) are masterfully sculpted from solid 950 Platinum—the rarest and most prestigious metal in fine watchmaking. The surfaces display a flawless mirror-polished finish that radiates a majestic white metallic luster.

The visual canvas is elevated by a solid 950 Platinum dial disc treated with a sophisticated sand-blasted satin finish, creating an elegant frosted face that catches light with subtle prestige. As an absolute mark of nobility, a discreet “Pt950” hallmark is stamped between 4 and 5 o’clock. 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 the transparent caseback, the hand-finished caliber is beautifully displayed, while satisfying a daily-resilient 3 bar (30m) water resistance behind a scratch-resistant sapphire shield.

SIEMPRE METICULOUS DUAL-COMPLICATION INTERFACE DRIVEN BY HIGHEST SCANNABILITY

The layout of this Grand Complication interface is purposefully calculated to be clean and highly scannable, dividing its complex metrics across perfectly balanced focal zones:

1. At 12 O’clock: Houses the majestic open anti-gravity tourbillon aperture carriage frame. Positioned boldly at the top of the dial via an advanced intermediary wheel on the seconds display, this mechanical layout enables a significantly larger opening on the mechanism. The hand-polished cage structure incorporates the Maltese cross outline, carrying a dedicated indicator that tracks small seconds smoothly.
2. At 3 O’clock & 6 O’clock: Features a 45-minute chronograph totalizer counter and a precision linear power reserve indication indicator.
3. The Outer Perimeter zone: A traditional circular railroad-type minute track is beautifully paired with a sharp tachymeter scale tracking speed. The central hour and minute hands are crafted into elegant 18K gold Dauphine-style profiles, swept alongside applied gold markers, while the chronograph metrics use blued hands (in steel for seconds, and 18K gold for minutes and power reserve) for advanced eligibility.

MANUFACTURE CALIBER 3200/260 ENGINE: THE SUPREME ART OF MONOPUSHER CHRONOGRAPH

Ensuring absolute operational precision and tactile authority is the high-performance mechanical hand-wound caliber movement, Caliber 3200/260, calculated, constructed, and hand-decorated entirely within Vacheron Constantin’s foundry in Geneva. Measuring a balanced diameter scale of 32.8mm and an ultra-thin movement profile of just 6.7mm thickness, this engine consists of 292 individual components and 39 jewels, operating at a frequency of 18,000 vibrations per hour (2.5 Hz).

The caliber integrates a high-complication column-wheel mechanism controlling a single-push (monopusher) chronograph function, meaning the wearer can Start, Stop, and Reset the stopwatch seamlessly through a single pusher built into the crown. Utilizing a manual-winding engine establishes an intimate connection between the collector and the watch, while the movement supplies an exceptional power reserve of 65 hours (nearly 3 days of autonomy) under the strict regulations of the supreme Geneva Seal.

PREMIUM DARK BLUE ALLIGATOR STRAP HAND-STITCHED WITH PURE PLATINUM THREAD

To honor the ultimate rarity of this 50-piece collection milestone allocation, the timepiece arrives on a premium alligator leather strap executed in a rich dark blue tone, introducing a bold, deeply prestigious contrast against the platinum chassis. Reflecting uncompromised luxury down to the final detail, the strap is hand-stitched with a proprietary thread woven from pure 950 Platinum metal wire. Secured to the wrist by an authentic 950 platinum triple folding security clasp shaped to echo the lines of the Maltese Cross emblem, this contemporary masterpiece commands absolute distinction in the most exclusive lifestyle circles.
