1910s Chronomètre Faux-Hallmark 585 Export watch

Updated September 15, 2026

Vintage 1910s Swiss mechanical open-face pocket watch featuring a 52.53mm base metal export case finished in a heavy gold-filled plate. The inner caseback features decorative pseudo-hallmark stamps displaying a faux "585" numeric purity mark alongside a cluster of three unauthorized five-pointed stars in shields, a period-correct factory fabrication designed to mimic official European assay marks. The interior dust cover lid (cuvette) features an elaborately engraved medal exhibition track reading "ANCRE DE PRECISION 20 RUBIS". The white enamel-style railroad dial showcases bold black Arabic hour tracks, a red outer 12-hour numeral marker, an inner printed red 24-hour military timeline from 13 to 24, fancy gold-gilt filigree Louis XIV-style hands, and cursive central dial script reading "Chronomètre". The watch is powered by a high-grade, gold-gilt Swiss mechanical movement running an advanced 20 jewels configuration.This mechanical pocket watch is running as of the time of listing, though a professional service is required for accurate timekeeping, and extended runtime without service is not guaranteed.
