T149.462.11.011.00 First introduced in the 1960s, the 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. With speed and heart rate tracked on the bezel, and time clearly displayed on the white dial with blue accents, this design offers a seamless and intuitive experience, evoking the limitless sky and the boundless potential ahead. The counters, positioned on the lower part of the dial, enhances the watch’s dynamic look.
