An exceptionally rare LeCoultre UniPlan in solid 18k yellow gold, dating to the late 1930s. With its striking Art Deco architecture, uncommon Swiss-market configuration, and breathtaking original black sector dial, this is a true collector's piece from one of LeCoultre's most innovative periods.
The beautifully proportioned 20 × 35 mm case, measured including its distinctive hinged lugs, is crafted in solid 18k yellow gold and showcases the elegant external centre-lug design that makes the UniPlan instantly recognizable. Unlike the majority of LeCoultre watches produced for export to the American market, this example was manufactured entirely in Switzerland, making it an exceptionally scarce variant.
Its greatest highlight is undoubtedly the original matte black sector dial, signed "LeCoultre". Featuring rich golden accents, a perfectly balanced sector layout, and a recessed small seconds register, it is an extraordinarily rare configuration. Original black sector dials of this quality are seldom encountered and are among the most desirable vintage LeCoultre dials ever produced.
Powering the watch is the manually wound LeCoultre UniPlan calibre, the same movement architecture used in the earliest Reverso models. Freshly serviced and running excellent, it offers both historical significance and reliable performance.
