Tissot PRX Automatic Chronograph 42mm Mens Watch
Ref. T1374271101100
Sits in Tissot’s upper tier here — more premium than three quarters of the Tissot watches we list, which start at £245.
Price range £245 to £1,875 across 310 Tissot watches in stock.The PRX was first introduced in 1978, and when Tissot revived the line in 2021 the defining characteristic was its flatness — the quartz and Powermatic 80 variants sit at 10.4mm and 10.9mm respectively, reading almost like dress watches. Adding a mechanical chronograph changes that calculus entirely. The Valjoux A05.H31 is a capable, well-regarded movement with a 60-hour power reserve and a Nivachron balance spring that resists magnetic and thermal interference, but it needs room. At 14.5mm this is a meaningfully different proposition from its siblings, and anyone expecting the same profile should know that going in. On the wrist the mass is noticeable — 184g against the three-hand automatic's 138g — but the integrated bracelet distributes it well enough that reviewers found it less top-heavy than the thickness suggests. The white panda dial, with rose gold-toned baton markers and sub-dials at three, six and nine, reads cleanly; the domed, anti-reflective sapphire helps at difficult angles. Half-links are included for sizing, which matters on a bracelet with no micro-adjustment at the clasp. The brushed steel picks up fingerprints and fine scratches readily, and the bezel finishing is functional rather than fastidious — something you will notice once you have owned it a while.

Learn more about Tissot
Charles-Félicien Tissot and his son Charles-Émile founded the company in Le Locle in 1853, assembling gold pocket watches and, unusually for the time, exporting aggressively — Russia became a major market within a decade.
Tissot's history is a sequence of firsts achieved through willingness to try materials and ideas the establishment considered unserious. The first mass-produced pocket watch with two time zones came in 1853. The first anti-magnetic wristwatch in 1930. The Astrolon of 1971 was the first watch with a movement made largely of injection-moulded plastic, and it worked. The RockWatch of 1985 used Alpine granite for the case, followed by watches in wood and mother-of-pearl.
The T-Touch of 1999 was the most significant: a tactile sapphire crystal allowing the wearer to access altimeter, barometer, compass, thermometer, and chronograph by touching the glass, years before touchscreens were commonplace.
Tissot merged with Omega in 1930 and both became founding members of what is now the Swatch Group. Its position in the group is volume and accessibility — Swiss mechanical and quartz watches at prices most people can reach, with the Powermatic 80 movement offering an eighty-hour reserve at entry level.
The company has held timekeeping roles across cycling, basketball, motorsport, and fencing.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedWhat size strap does it take?
13mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's.
