Stepping up in the same dial colour
The PRX line traces back to a 1978 integrated-bracelet design, and this digital version is the most literal possible answer to the question of what that watch would have been had LCD technology been central to its brief from the start. The calibre designation, 4012, is a deliberate nod to Tissot's original 1970s digital quartz work, though the movement underneath is a modern Swiss-made unit built for the full range of functions — GMT, chronograph, alarm, countdown — that the period original could never have managed. At 10.9mm thick it is remarkably flat for what it carries, and the tonneau case with its rigidly integrated first links pushes across the wrist in a way that reads as deliberate presence rather than bulk. The mirrored surround to the LCD window gives the dial a cohesive, almost monolithic face, and the backlight does the job that lume would do on an analogue sibling — adequately, without fuss. Medium to large wrists will find the proportions natural; smaller ones may find it commands more of the wrist than expected.

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?
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 44mm, 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 unisex, and at this size it suits any wrist that takes the dimensions.
