Tissot PRX UFO Robot Grendizer 40mm Mens Watch Blue
Ref. T1374071104102
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 1978 original, and this 2024 edition pulls in a second set of references entirely — the Japanese manga series UFO Robot Grendizer, which ran through the 1970s as a cultural touchstone across Japan and much of the Arab world. The robot's bust is embossed at the centre of the sunbrushed blue dial, its indices and hands sharing Super-LumiNova with the figure itself, which glows yellow in the dark. The inner rim carries the original Japanese title, and the movement rotor is engraved with Grendizer imagery — details visible through the exhibition caseback that give an owner things to find gradually rather than all at once. The tonneau case shape means 40mm reads smaller on the wrist than a round case at the same stated width, sitting flush and low against the wrist on the integrated bracelet. That 80-hour power reserve is a genuine advantage on a watch that may spend weekends being admired rather than worn, and the Nivachron balance spring holds accuracy without depending on a magnetic-free environment. The crown is engraved, as these things should be when the rest of the watch is this considered.

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.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
