Vacheron Constantin Harmony Dual Time Limited Edition 7810S/000R-B051: A Horological Homage to 260 Years of Mastery

In the rarefied world of haute horlogerie, few names resonate with the weight of history and craftsmanship like Vacheron Constantin. Founded in 1755, the maison has spent centuries perfecting the art of timekeeping, and in 2015, it unveiled a collection that crystallized its legacy: the Harmony series. Among its standout pieces is the Harmony Dual Time Limited Edition 7810S/000R-B051, a watch that sings with historical reverence, technical brilliance, and aesthetic finesse. Limited to just 625 pieces, this pink gold marvel isn’t just a timepiece—it’s a love letter to 260 years of watchmaking excellence. Let’s dive into why this watch is a collector’s dream and a horologist’s delight.

A Historical Tapestry Woven in Gold

Picture this: it’s 2015, and Vacheron Constantin is celebrating its 260th anniversary, a milestone unmatched by most in the industry. To mark the occasion, the brand unveils the Harmony collection at SIHH, drawing inspiration from a 1928 cushion-cased chronograph—a nod to the past that feels thrillingly modern. The Harmony Dual Time 7810S/000R-B051 emerges as a centerpiece, its 18K pink gold case gleaming with purpose. Each of the 625 pieces carries an engraving on the caseback: “260th Anniversary.” It’s not just a watch; it’s a tangible piece of history, bundled with a luxurious presentation box, a magnifying glass, a Harmony brochure, and a letter signed by then-CEO Juan-Carlos Torres himself. This isn’t just exclusivity—it’s intimacy with a legacy.

The cushion case, a hallmark of the Harmony line, harks back to the elegant designs of the early 20th century, when watches began transitioning from pockets to wrists. Yet, Vacheron doesn’t merely mimic history; it reinterprets it. The 7810S/000R-B051 blends vintage proportions with contemporary refinement, creating a timepiece that feels both timeless and forward-looking. For those who geek out over horological heritage, this watch is a bridge between eras, a conversation starter that whispers of Geneva’s watchmaking ateliers.

Horological Artistry: The Caliber 2460DT

At the heart of this masterpiece beats the in-house caliber 2460DT, a self-winding movement that’s as much a work of art as it is a technical marvel. Certified with the prestigious Hallmark of Geneva, it’s a guarantee of meticulous craftsmanship—every component polished, beveled, and decorated to perfection. Peer through the sapphire caseback, and you’re greeted with a visual symphony: Côtes de Genève ripple across the bridges, Circular Graining adorns the mainplate, and the gold rotor, etched with a bespoke 260th anniversary pattern, spins with quiet elegance.

The 2460DT is built for function as much as beauty. With 233 components and 27 jewels, it hums at 28,800 vibrations per hour (4 Hz), delivering a smooth, reliable performance. Its 40-hour power reserve is practical for daily wear, while the dual time zone complication, complete with a day/night indicator, makes it a globetrotter’s companion. Whether you’re jet-setting between Geneva and Tokyo or simply dreaming of it, this movement ensures you’re always on time, in style. It’s the kind of engineering that makes you want to applaud—Vacheron’s watchmakers clearly poured their souls into every gear.

The Cushion Case: A Design Icon Reborn

Let’s talk about that case. The cushion shape of the 7810S/000R-B051 is a stroke of genius, blending soft curves with sharp edges to create a profile that’s distinctive yet versatile. Crafted from 18K pink gold, it measures 40 mm in width, 49.30 mm lug-to-lug, and a svelte 11.43 mm in thickness—proportions that sit comfortably on most wrists, exuding understated confidence. The polished finish catches the light with a warm glow, while the sapphire caseback invites you to lose yourself in the movement’s intricacies.

This isn’t just a case; it’s a canvas. The cushion design pays homage to Vacheron’s early wristwatches, yet its modern execution feels fresh and bold. At 30 meters of water resistance, it’s not a dive watch, but it’s more than capable of handling life’s splashes. Whether paired with a suit or a casual sweater, this watch commands attention without shouting—a true mark of sophistication.

Dial and Details: Where Elegance Meets Utility

The opaline silvered dial is a study in balance. Leaf-shaped hands glide over applied hour markers, with Roman numerals at 12 and 6 adding a classical touch. The dual time zone sub-dial at 6 o’clock is intuitive, with a day/night indicator that’s as practical as it is charming. A central seconds hand sweeps gracefully, tying the design together with precision. Protected by a sapphire crystal, the dial is a window into Vacheron’s obsession with detail—every element feels deliberate, harmonious, and alive.

The alligator strap, hand-stitched and paired with a pink gold buckle, completes the package. It’s the kind of strap that feels like it was made for your wrist, aging beautifully with wear. This is a watch that doesn’t just tell time; it tells a story—of craftsmanship, heritage, and the pursuit of perfection.

Why It Matters

The Vacheron Constantin Harmony Dual Time Limited Edition 7810S/000R-B051 is more than a watch—it’s a milestone. With only 625 pieces in existence, it’s a rare gem that captures the essence of a 260-year-old maison. It’s a collector’s piece, yes, but it’s also a wearer’s delight, blending high horology with everyday usability. The caliber 2460DT, the cushion case, the Hallmark of Geneva certification—these aren’t just features; they’re proof of Vacheron’s unrelenting passion for the craft.

For those who live and breathe watches, this is the kind of timepiece that sparks obsession. It’s a reminder that in an industry often driven by trends, Vacheron Constantin remains a beacon of tradition and innovation. If you’re lucky enough to strap one on, you’re not just wearing a watch—you’re carrying a piece of history, ticking proudly on your wrist.
