Vintage Herzfeld 17 Rubis Mechanical Wristwatch

This is a vintage mid-century style men's dress watch branded 'Herzfeld'. The timepiece features a round, gold-tone metal case, likely gold-plated or gold-filled, with a diameter estimated between 34mm and 36mm consistent with mid-20th-century sizing. The dial is a champagne or light metallic gold finish, decorated with bold, oversized black rectangular hour markers that give it a distinctive modernist aesthetic. The hands are matching gold-tone batons with black inlays for visibility. Significant markings on the dial include the 'Herzfeld' brand name and logo at the 12 o'clock position and the text '17 RUBIS' above the 6 o'clock position, indicating a manual-wind mechanical movement with 17 jewels. The watch is fitted with a simple black leather strap. Regarding condition, the case shows moderate wear with light scratching and possible brassing on the lugs and crown, typical of an aged gold finish. The acrylic crystal appears relatively clear but may have fine surface abrasions. The dial shows a light, even patina without significant water damage or staining. The overall design suggests a manufacturing period during the late 1960s to early 1970s. The craftsmanship represents a solid Swiss-made or European-made entry-level luxury movement common to that era.
