Stepping up in the same colour and case shape
The PRC 100 dates to the mid-2000s and has returned with its original silhouette intact, now paired with Tissot's Lightmaster movement — a solar system that draws energy through the underside of the sapphire crystal itself, which is why the dial can be finished properly rather than dominated by a visible cell. On a full charge the reserve runs to 14 months; if the watch has been kept in the dark for that long, the seconds hand begins jumping in four-second increments to tell you so. At 34mm the case reads larger on the wrist than that diameter implies, owing to a 44.6mm lug-to-lug span that gives it genuine presence without pushing into territory that sits awkwardly on a narrower wrist. The sunburst blue dial shifts register depending on the light — cooler and more subdued indoors, brighter in daylight — and the Super-LumiNova on the hands and indexes means it remains legible long after the sun has done its work charging the movement.

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 charges from light, and the cell behind that is designed to last a decade or more.
Quartz, automatic and solar comparedWhat size strap does it take?
18mm. 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 44.6mm, which suits wrists from roughly 16cm (6¼ 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 women's, though at 34mm it sits in the range that suits anyone.
