Louis Erard x Vianney Halter Le Régulateur II, in silver
Vianney Halter, the independent watchmaker behind Le Régulateur’s industrial design, returns with Louis Erard for a second regulator, now in a silver monochrome dial.
Louis Erard today introduces the Worldwide edition of the Le Régulateur Louis Erard x Vianney Halter II, limited to 178 pieces. It is the second Régulateur the two have designed together, and it launches as part of a wider World Tour.

The design is rooted in Vianney Halter’s 1998 Antiqua: red-gilt rivets ring the bezel, and a rivet-set crown sits at 2 o’clock. On the new silver dial, the hours sit in a counter at 11 o’clock and the seconds at 5, while a blued hand sweeps the minutes from the centre. Halter designed the dial himself, and the steel case is finished with polished and circular satin-brushed surfaces.
“This is more than a collab. It’s a creative collision between Vianney Halter, master of Steampunk horology and Louis Erard’s signature Regulator,” says Manuel Emch, who leads Louis Erard.
The result keeps the deconstructed spirit of Halter’s 1998 Antiqua, made now to be worn every day.
