Louis Erard x Alain Silberstein - Smile-Day Blue & Régulateur Tourbillon Blue
In the world of fine watchmaking, collaborations are often expected. But when Louis Erard joins forces with the legendary Alain Silberstein, the result is anything but ordinary. We are thrilled to introduce the next chapter of this storied alliance: the launch of the Louis Erard Hall of Fame collection, with two spectacular new models—the Smile-Day Blue and the Régulateur Tourbillon Blue.
As Manuel Emch, the driving force behind Louis Erard, puts it: “Our collaborations with Alain Silberstein are never ordinary. They are stories to be worn on the wrist, where every detail matters. The Hall of Fame offers them a lasting setting, a space where these creations span the years and continue to surprise.”
Smile-Day Blue: Living the Day with Emotion
The Smile-Day Blue is a masterclass in functional whimsy. At its heart lies a complication that only Silberstein could conceive. At 6 o’clock, a day disc reveals a smiley face that reflects the mood of the week: black from Monday to Friday, turning a joyful red on the weekend, with the smile growing as the days progress. It is a visual reminder that time is not just measured, but experienced.
Beneath this playful exterior lies the rigorous architecture of a Swiss automatic movement (Sellita SW220-1). The hypnotic blue sunray dial serves as the perfect backdrop for Silberstein’s signature visual language:
Red triangular hour hand
White arrow-shaped minute hand
Yellow serpentine seconds hand
These simple shapes and primary colors ensure immediate legibility and a striking aesthetic. Housed in a robust 40mm micro-blasted titanium case, the Smile-Day Blue is finished with a signature red lacquered crown and secured by an ultra-comfortable heathered blue nylon strap with a velcro closure—offering a perfect fit without the bulk of a traditional buckle.
Régulateur Tourbillon Blue: At the Heart of Time
For those who demand technical mastery alongside artistic expression, the Régulateur Tourbillon Blue represents the pinnacle of the collaboration. This timepiece is a feat of engineering, housing a tourbillon regulator movement developed exclusively for Louis Erard by the visionary watchmaker Olivier Mory in La Chaux-de-Fonds.
Visible through a cut-out at 6 o’clock, the tourbillon cage performs its hypnotic dance, completing a full rotation every 60 seconds. This complex mechanism is framed by a classic regulator layout: the hours are displayed in a sub-dial at 12 o’clock, while the central hand tracks the minutes. The yellow serpentine second hand traces a fluid path over the tourbillon, maintaining the visual codes of its Smile-Day sibling.
The 40mm micro-blasted titanium case offers a lightweight, ergonomic feel on the wrist. Like its counterpart, it features the same vibrant blue sunray dial, the iconic red/white/yellow handset, and the innovative Velcro strap system for unmatched comfort.
A New Home for Legends: The Hall of Fame
The Hall of Fame is more than a new collection; it is a revolutionary ecosystem designed to balance rarity with permanence. It creates a curated space where select collaborations—like those with Alain Silberstein—are enshrined not as fleeting limited editions, but as enduring pillars of the brand’s identity.
