Introducing: Louis Erard X Vianney Halter Le Régulateur II World Tour. A Distinct Seconds Hand and Engraving by City.

In an industry where tradition sometimes takes precedence over innovation, and reverence for heritage can sometimes stifle creative expression, two forces have collided once again to shatter every expectation of what a watch launch should be. Louis Erard and Vianney Halter are back at it, orchestrating a horological revolution, one city at a time. The new Louis Erard X Vianney Halter Le Régulateur II World Tour Edition goes monochrome with a new silver vertical satin-brushed dial and its signature blued hands.


The Art of the Drop

Forget everything you know about Swiss watch releases. Gone are the predictable retail roll outs. In their place: limited drops, and the thrill of the chase that transforms collectors into hunters. Le Régulateur Louis Erard x Vianney Halter II World Tour isn't just arriving—it's landing like a rare sneaker release, with the same breathless anticipation and zero-tolerance-for-delay mentality that defines today's most coveted cultural moments.

This isn't merely a collaboration; it's a creative collision between Vianney Halter, the master of steampunk horology whose 1998 Antiqua redefined what a luxury watch could look like, and Louis Erard's signature regulator aesthetic in a fusion that feels both inevitable and absolutely electric.

Their previous collaboration—the second ever—yielded two two-tone watches integrating Steampunk craftsmanship and the distinctive codes of Antiqua into the Régulateur. The two different references where cased in stainless steel with 12 polished red-gilt 5N rivets around the bezel, and a rhodium-plated base dial or a red-gilt 5N one plate—salmon colored—with reversed color combination for each model.


The Power of Scarcity

With only 178 monochrome editions available worldwide and city drops limited to 18-25 pieces each, Louis Erard and Halter have created something rarer than most haute horlogerie: genuine scarcity in an age of endless production. This isn't artificial limitation for marketing purposes—it's the natural result of treating each watch as a cultural event rather than a commercial transaction.

The tour format itself represents a fascinating evolution in luxury retail. By transforming sales points into stages and releases into events, they've imported the communal excitement of concert tours into watchmaking. Suddenly, acquiring a timepiece becomes about more than ownership—it's about participation in a moment, a city, a story.


Color-Coded Conquest

The genius lies in the execution: one monochrome foundation, infinite possibilities for personalization. Each city on the world tour receives its own distinctive seconds hand color—rhodium for Takamatsu's refined sensibility, anthracite for Bangkok's urban edge, purple for Hong Kong's vibrant energy, red-gilded for Singapore's luxury landscape. It's geographic storytelling through color, turning each limited release into a cultural artifact that captures the essence of its host city.

But perhaps most intriguingly, Halter's legendary motto "Live Long and Prosper"—borrowed from science fiction but perfectly suited to his own boundary-pushing philosophy—appears engraved in different languages on each city edition's case back. It's a detail that transforms these watches from mere timepieces into cultural ambassadors, carrying local languages and global aspirations on the same wrist.

The 25-piece Japan drop—at Eye Eye Isuzu—will have the phrase in French: “Longue vie et prospérité“; the 18-piece Bangkok drop—at PMT The Hour Glass—will have the phrase in English: “Live long and prosper”; the 25-piece Hong Kong drop—at The Lavish Attic—will have the phrase in Chinese; and the 25-piece Singapore drop—at The Hour Glass—will have the phrase in English: “Live long and prosper”. More cities and dates coming soon.


Beyond the Regulator

Still cased in stainless steel and measuring 43 mm in diameter, the dial features an hours counter at 11 o’clock, a central minutes hand, seconds counter at 5 o’clock with a vertical satin-brushed finish, and circular satin-brushed with diamond-polished chamfers chapter ring and counter rings, black transfers, Louis Erard logo at 2 o’clock and Vianney Halter logo at 8 o’clock. Dial designed by Vianney Halter with his artistic identity Vianney Halter signature hands in blued steel. The bezel and the crown maintain the polished red-gilt 5N rivets.

At its mechanical heart still beats the reliable Sellita SW266-1 with 31 jewels, which provides a power reserve of 38 hours while beating at a frequency of 28,800 vph. Meticulously decorated and visible through a transparent case back that doesn't hide the craftsmanship but celebrates it.


Let the Chase Begin

As this horological world tour prepares to launch, one thing becomes clear: Louis Erard and Vianney Halter haven't just created a watch—they've engineered a new way to experience time itself. Whether you're drawn to the monochrome elegance of the worldwide edition or find yourself chasing a specific city's color-coded seconds hand, you're not just buying a timepiece. You're joining a movement that proves luxury can be both exclusive and exciting, traditional and revolutionary, Swiss and global.

The tour doesn't do replays. The question isn't whether you want to be part of this story—it's which chapter you'll choose to join.
