Patek Philippe 3718A Calatrava 150th Anniversary SS Ivory Dial

Presented in a seldom‑seen stainless steel case, the Patek Philippe 3718A Calatrava was crafted in 1989 as a limited edition of just 500 pieces for the Japanese market to mark the Maison’s 150th anniversary. Its 33 mm diameter and slender 7 mm profile house the revered manual‑wind Caliber 215 PS, celebrated for its ultra‑thin architecture, Geneva Seal finishing, and approximately 44‑hour power reserve. The ivory cream dial, adorned with applied baton indices and a small seconds subdial at 6 o’clock, offers a refined, minimalist aesthetic that perfectly complements the discreet elegance favored by connoisseurs. The solid snap‑on caseback is distinguished by a gilt medallion engraved “Patek Philippe – 1839–1989” encircling the Calatrava Cross, underscoring the commemorative nature of the piece. As one of the rare steel Calatravas from the late 1980s, this reference occupies a unique position in the brand’s history, blending dress watch purity with collector rarity. The manual movement’s finishing—visible through the craftsmanship of the architecture and hallmarking—speaks to Patek Philippe’s uncompromising standards, even in a steel execution. Its exclusivity, historical significance, and classical proportions make the 3718A a grail for discerning collectors seeking a discreet yet historically meaningful dress watch. Excellent Condition with Patek Philippe papers dated 1988.
