Period
Circa 1990
This Daniel Roth wristwatch features the maker's signature ellipsocurvex case in 18K yellow gold, measuring 38 mm wide by 41 mm long. Dated by the source to circa 1990, the watch is catalogued as part of a limited edition of 36 yellow gold examples powered by the manual-wind Calibre 2220, based on a vintage Lemania ébauche.
The dial combines a guilloché centre, Roman numerals on a brushed hour ring, two subsidiary dials, and blued steel hands with pointed tips. The bottom dial plaque bears the inscription 'NUMERO 20', matching the source-recorded case and movement number.
