NOTES: The Patek Philippe Calatrava 3718A is a standout among late 20th-century Calatravas due to its rare stainless steel case, a material seldom used by Patek Philippe at the time, as the brand typically favored yellow or white gold for its dress watches. Produced in 1989 to commemorate Patek Philippe’s 150th anniversary, the 3718A is part of a highly limited edition (≈500 pieces) released exclusively for the Japanese market, making it exceptionally rare outside Japan.
Its slate grey dial adds a subtle but striking variation from the more common ivory edition, giving it a distinctive aesthetic appeal. Powered by the manual-wind caliber 215 PS, a beautifully finished and historically significant movement, the watch combines refined mechanics with understated elegance, hallmarks of Patek Philippe design.
Collectors prize the 3718A not only for its limited production and anniversary significance but also for its uncommon steel case and unique dial color, which make it one of the most coveted mid- to late-20th century Calatrava references for both vintage enthusiasts and those seeking a discrete, high-quality Patek Philippe dress watch.
