A rare and mechanically sophisticated gem of post-war Swiss watchmaking, this vintage Oska Triple Calendar Pointer Date (Reference 19301) features one of the most coveted complications of the mid-20th century. Encased in a classic gold-plated case with sweeping teardrop-style lugs and a stainless steel back signed Fond Acier Inoxydable 19301, the watch showcases a two-tone silvered dial. It is beautifully arranged with golden raised Arabic numerals, dual day and month apertures below 12 o'clock, an outer perimeter 1–31 date track printed in high-visibility red, and a sunken sub-seconds register at 6 o'clock. At its mechanical heart sits the legendary Venus Caliber 203 17-jewel manual-wind movement, celebrated by collectors alongside Venus’s premier chronograph architecture for its intricate multi-calendar gearing and reliable performance. Fully operational, running accurately, and advancing through time, date, day, and month functions, this timepiece comes paired with a black alligator-grain leather strap, making it a standout addition for collectors of mid-century Swiss calendar complications.

History & Collector Appeal * Historical Significance: The 1940s and 1950s marked the golden era of mechanical calendar wristwatches, with famous movement maker Fabrique d'Ébauches Venus S.A. leading the Swiss industry in producing complex, high-reliability calibers like the Venus 203. While Venus is universally famous for powering premier chronographs (such as Breitling’s Navitimer and Premier lines), their non-chronograph triple-calendar movements are far scarcer and held in equally high esteem by horological purists. * Collector Appeal: "Pointer Date" and "Triple Calendar" configurations from independent Swiss houses represent some of the fastest-appreciating segments of mid-century vintage collecting. Finding an Oska equipped with an intact, authentic two-tone red-date dial and a fully functional Venus Caliber 203 movement in strong running order makes this listing an exceptional prize for serious collectors of vintage Swiss complications. * Production Year: Circa late 1940s to early 1950s.
