Crafted in the tradition of fine Swiss watchmaking, the Heritage Chronograph – Coquille d’œuf marks the beginning of a new chapter for Lebois & Co. This limited-edition timepiece features a rare, fully handcrafted Swiss Made Grand Feu enamel dial — composed of three separate parts, layered and fired at over 800 °C. The curved, multi-level surface is printed by hand using enamel-based inks, then fired once more to permanently fuse the graphics into the enamel. Each dial is produced in Le Locle, Switzerland, by Donzé Cadrans — one of the world’s most respected enamel specialists — using time-honoured techniques passed down through generations. The result: a radiant, living surface with organic variations. No two dials are exactly alike. To match the artistry of the dial, the Heritage Chronograph is housed in a refined 39 mm case and powered by a high-grade manual-wind chronograph movement. The subdials are recessed and soldered individually — a nod to the dial’s three-part construction. Available exclusively by souscription, and limited to just 25 pieces per year, this model opens a new era for the Heritage Chronograph collection — and celebrates the 90th anniversary of Lebois & Co, founded in 1934.
