The Louis Erard x Kudoke Le Régulateur is a four-variant limited-edition collaboration that combines Louis Erard’s regulator-style display with decorative details associated with Kudoke’s HANDwerk approach. The September 2024 launch report lists dial options in light blue, forest green, purple and white mother-of-pearl, with announced production limits of 78 or 100 pieces depending on the version.
What makes the display a regulator?
Instead of placing the hour and minute hands together at the centre, this watch separates the indications: minutes are shown by the central hand, hours by a subdial at 12 o’clock, and small seconds by a subdial at 6 o’clock. The launch article describes the hour hand as infinity-shaped and the hands as blued steel. Rhodium-plated, chamfered rings mark the minutes and subdials.
The dial treatment varies by version. The light-blue, forest-green and purple dials have a grained finish; the fourth option is white mother-of-pearl. The decorative execution is presented alongside Louis Erard’s three-hand regulator layout as a collaboration with Kudoke.
