Manufactured in the 1940s, this is an unnamed timepiece with a Valjoux 71 movement, measuring 36mm in diameter. It features a stepped design chronograph with a rare black two-tone dial. The black two-tone dial, with a gold circle created through a base polishing process, showcases the appealing patina of the radium indexes from that era. The watch's solid and sophisticated stepped design case, equipped with egg pushers, embodies the essence of the time and exhibits a magnificent taste.
This is a rare three-register chronograph from the 1940s, combining unique design characteristics of that era with the mechanical expression of a three-register chronograph. It is a valuable piece. Furthermore, the rarity of a black dial enhances its appeal. It is powered by the renowned Valjoux Caliber 71, an improved version of the Caliber 22 by Valjoux, a company that many brands, including Rolex, adopted.
