Tissot PRX Powermatic 80 35mm Steel and 18K Gold Bezel Ladies Watch
Ref. T9312074111100
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 349 Tissot watches in stock.The PRX line reaches back to a Tissot case shape from 1978, and this 35mm version carries the same integrated-bracelet geometry and tonneau silhouette as the original — smooth, low-slung, deliberately of its era. The rose gold bezel, in solid 18K, lifts that foundation without changing its character: the proportions remain those of a restrained seventies dress watch, and the mother-of-pearl dial, with its rose gold tone hands, answers the bezel rather than competing with it. At 35mm the case sits squarely on smaller wrists without overhang, and the lug-to-lug measurement of 34.60mm — shorter than the case is wide — keeps it nestled close to the wrist rather than bridging across it. The Powermatic 80 movement behind the see-through caseback is built around a Nivachron balance spring, a non-ferrous alloy that resists magnetic interference better than traditional materials, which matters more than it once did given how much electromagnetism most people now carry daily. Eighty hours of power reserve means leaving it off the wrist on Friday and returning to it Monday without a winding ritual.

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 comparedHow long does it run for when it's not worn?
About 80 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What size strap does it take?
11mm. 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 women's, though at 35mm it sits in the range that suits anyone.
