Louis Erard x Vianney Halter – Le Régulateur II 85246AA01.BVA180
A distillation of Vianney Halter's unique universe: bold, independent, and instantly recognizable.

When Vianney Halter reinvents time with Louis Erard
Independent watchmaking at its peak: the new Louis Erard x Vianney Halter Régulateur II doesn’t just tell the time, it reinvents it. Designed in collaboration with independent master watchmaker Vianney Halter, this iconic creation transcends traditional codes to offer a unique and unforgettable way of reading the time.
A signature design, somewhere between steampunk and Antiqua
The Louis Erard x Vianney Halter II Régulateur follows on from the first edition, drawing inspiration from the world of steampunk and the inimitable aesthetic of the Antiqua, Halter’s legendary timepiece. Here, time is broken down and colored: hours, minutes, and seconds stand out to create a world that oscillates between reality and fiction, between past and future.
A bold and indomitable 42 mm riveted case
Every detail of the Régulateur II asserts its difference:
A 42 mm steel case enhanced with twelve iconic rivets.
An inclined crown, the signature of an unconventional design.
Blue-steel hands with an electric look, reflecting Vianney Halter’s creative audacity.
The result is a riveted, twisted, unstoppable piece designed to challenge the conventions of traditional watchmaking.
The return of an icon
The Louis Erard x Vianney Halter II Regulator returns more striking than ever, with a new monochrome silver dial that enhances readability and highlights its iconic hands. This edition reinforces the strong identity of the collaboration, affirming once again that Louis Erard and Vianney Halter together create much more than a watch: a work of horological art.
