The Tissot PRX, relaunched in 2021 from a 1978 design, is a quartz sports watch with an integrated bracelet. The 40 mm reference T137.410.11.041.00 has a stainless steel case with a bezel and a “waffle” dial, a sapphire crystal and a water resistance of 100 metres.

The original PRX appeared in the late 1970s, the era of the Royal Oak and the Nautilus, and Tissot brought it back at an accessible price. The relaunch was followed by automatic Powermatic 80 versions, which the site lists as separate watches, and by 35 mm and other sizes.

The PRX was a big commercial and critical success, widely described as the best-value integrated-bracelet watch of its generation. It remains in production.
