And while Tissot is probably not the first brand that leaps to mind when you think of motorsports-inspired timepieces, it was indisputably one of the pioneers of that genre, a style most clearly and boldly expressed in the PR516 collection, a mainstay of the Tissot portfolio that has undergone a significant, vintage-inspired refresh in 2024. Tissot's association with motor racing, and the seed from which the original PR 516 (originally spelled with a space between letters and numerals, and later hyphenated) would spring, began with what was essentially a fan letter from a satisfied customer. In 1958, Tissot received a signed photograph from a Swiss racing driver named Harry Zweifel, which was accompanied by a note in German that read, " Meine Tissot ist an jedem Rennen dabei," or "My Tissot is at my side in every race."
