Tissot PRX watches

The Tissot PRX is a steel sports watch with an integrated bracelet, brought back in 2021 from a Tissot case shape of 1978. Its design follows the Seastar ref. 40205 of that year. Tissot relaunched it as a quartz watch in early 2021 and added the automatic PRX Powermatic 80 a few months later. The case runs straight into the bracelet; lug width is 12 mm on the 40 mm models and 11 mm on the 35 mm, and the three-hand models are water resistant to 100 m.

The PRX Powermatic 80 (T137.407) is the 40 mm, 10.9 mm automatic. Its Powermatic 80.111 is an ETA C07.111, derived from the ETA 2824, beating at 21,600 vph with a Nivachron balance spring and running for 80 hours. Its dial carries a chequerboard pattern that recalls the tapisserie of the Audemars Piguet Royal Oak. The PRX Quartz (T137.410) keeps the 40 mm case at 10.4 mm thick, and the PRX 35 mm quartz (T137.210) returns to the 35 mm of the 1978 original, at 9.6 mm.

The steel models come in blue, black, green or silver, on the bracelet or on a strap, such as the Powermatic T137.407.16.041.00. The gold-toned T137 models are PVD over steel: the rose gold PVD Powermatic T137.407.21.031.00 and the yellow gold PVD quartz models with champagne dials, T137.410.33.021.00 at 40 mm and T137.210.33.021.00 at 35 mm. The T931.407.41 Powermatic models are different: their bezel is 18K rose gold on the steel case, over a blue or brown dial.

The PRX Chronograph (T137.427) arrived in 2022 in a 42 mm case with the automatic Valjoux A05.H31, a 60-hour power reserve and a date at 4:30, with a silver dial and black counters or in blue. The T077.417 references are 40 mm quartz chronographs that also carry the PRX name, in steel with black, blue or silver dials, or with yellow gold PVD.
