Tissot PRX Automatic 40mm Mens Watch White Mother Of Pearl
Ref. T1374071111100
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 £2,740 across 382 Tissot watches in stock.The PRX case shape dates to 1978, and the proportions it established — the tonneau form, the integrated bracelet flowing uninterrupted from the lugs — have aged well enough that Tissot revived it largely intact. What this version does differently is lay a mother-of-pearl dial inside that angular architecture, a material whose organic surface shifts colour with the light in a way that reads as unexpected against the geometric case lines. At 39.5mm lug to lug and just under 11mm thick, it sits closer to the wrist than most 40mm watches, and the integrated bracelet is doing a good deal of work there: because the band meets the case without a gap, the whole thing moves as one piece rather than sitting on top of the wrist. The Powermatic 80.111 under the sapphire caseback is a developed ETA 2824 with a Nivachron balance spring — non-ferrous, so it resists magnetic interference — and an 80-hour reserve that means leaving it on the nightstand Friday evening and picking it up Monday morning without winding it first. Link adjustment and strap changes require no tools.

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?
12mm. 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.
Will it fit my wrist?
Lug-to-lug is 39.5mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
