Description

The Heritage Atelier Chronograph Coquille d’œuf celebrates the artistry of traditional Swiss enamel craftsmanship through one of the most complex dials ever created by Lebois & Co.

Produced in Le Locle, Switzerland, by renowned enamel specialist Donzé Cadrans, each dial is composed of three individually crafted Grand Feu enamel elements. Layer by layer, enamel is applied and fired at temperatures exceeding 800°C before the separate components are assembled into a single multi-level dial. The curved central section, recessed subdials, and vintage-inspired pulsation scale create remarkable depth while preserving the elegance of mid-century chronographs.

The graphics are printed by hand using enamel-based inks and fired once more to permanently fuse them into the enamel surface. The result is a luminous dial with subtle organic variations, ensuring that no two examples are exactly alike.

Housed in a refined 39 mm case and powered by a hand-wound column-wheel chronograph movement, the Heritage Atelier Chronograph Coquille d’œuf is available exclusively by souscription and limited to just 25 pieces per year.

Supplied by the brand to the GPHG for its entry.
