First introduced in the 1960s, the Tissot PR516 was inspired by the high-speed world of car racing. As Tissot expands the PR516 line, it continues to fuel the spirit of those who seek a timepiece as relentless as their pursuits—driving them to face challenges head-on, just like the heroes who wear it. The Valjoux chronograph, tachymeter, and pulsometer work in unison, and are built to capture every beat when life feels exhilarating.
