Louis Erard x Vianney Halter: A visionary watch for those who dare to dream and stand out.

Louis Erard x Vianney Halter II: A journey through time and space
Discover the bold new collaboration between Louis Erard and Vianney Halter with the Régulateur II, a watch where unstructured design and Steampunk aesthetics meet to push back the boundaries of traditional watchmaking. Inspired by Halter’s iconic Antiqua, this unique timepiece redefines the very idea of time with a subdivided, asymmetrical display, while marrying a retro-futuristic aesthetic with haute horlogerie finishes.
Key features:
Steampunk heritage: Inspired by the revolutionary design of the 1998 Antiqua.
Retro-futuristic design: Gold rivets, riveted bezel and crown evoke 19th-century industrial machinery.
Unstructured display: Asymmetrical counters and off-centered crown at 2 o’clock for an unprecedented reading of time.
High-end finishes: Polished and diamond-polished corners, vertical and circular satin-finishing.
Blued steel hands: an elegant signature shared by both watchmakers.
Embossed dial elements: Distinctive Halter typography in tribute to the creator.
Brown calf leather strap: Vintage grain for timeless style.
Limited edition: 178 pieces.
A creative friendship in the service of the exceptional
For Manuel Emch, this collaboration is above all a human adventure marked by unexpected and memorable moments. “With Vianney, every detail of this watch was designed to exceed expectations, while remaining faithful to the codes of independent watchmaking. An unusual piece, but designed to be worn every day.”
