The Tissot PRS 516 collection draws its roots from the 1960s motorsport world. These watches offer their wearers a blend of Swiss watchmaking innovation and classic racing-inspired design elements. On some models, the movement can be seen working through the distinctive case back designed like the steering wheel of a pioneering sports car.
