Louis Erard Le Régulateur x Vianney Halter II Monochrome | LE178

The new Le Régulateur Louis Erard x Vianney Halter II returns with its unmistakable design, now elevated by a striking silver monochrome dial that sharpens its modern presence. Signature electric blued steel hands glide across matching sub-dials, complemented by a dark blue leather strap that mirrors their intensity. Inspired by Vianney Halter’s groundbreaking Antiqua, this timepiece embraces an industrial edge with a riveted bezel, red-gilt rivets, and an offset crown at two o’clock. Its deconstructed display, complete with split-time sub-dials, reinforces the watch’s bold character, while haute horlogerie finishing, from diamond-polished angles to satin-brushed textures, underscores its meticulous craftsmanship.

A limited edition of 178 pieces.
Ref. 85246AA01.BVA180

Powering the watch is the automatic Sellita caliber SW266-1, a precision regulator movement with 31 jewels, 28,800 vibrations per hour, and a 38-hour power reserve. Visible through the sapphire crystal caseback, the open-worked oscillating weight features a black lacquered Louis Erard symbol, a detail that reflects both artistry and mechanical depth. With a 43 mm stainless steel case, sapphire crystal treated with anti-reflective coating, and water resistance to 50 meters, Le Régulateur Louis Erard x Vianney Halter II combines striking design with robust performance. Finished with a dark blue calf leather strap and Vianney Halter’s artistic imprint, this limited edition collaboration transforms timekeeping into an expressive statement of individuality.
