Stepping up in the same colour and case shape
The PRC 100 first appeared in the mid-2000s as one of Tissot's more sport-forward designs, and this revival brings it back with something the original never had: a solar movement that removes battery changes from the ownership experience entirely. Microscopic photovoltaic cells sit beneath the dial in a honeycomb arrangement, feeding a rechargeable cell that holds enough charge for fourteen months in the dark — and when reserves finally run low, the second hand shifts to four-second jumps rather than stopping without warning. At 34mm the case carries a twelve-sided bezel that reads as purposeful without being aggressive, and the silver dial keeps things legible without much ceremony — stick indexes, luminous hands, date at three. The 9.14mm case depth is notably restrained for a watch rated to 100 metres, which means the bracelet lies flat and the whole thing tucks under a cuff without the bulk that solar movements sometimes bring with them.

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.
Is it a men's or women's watch?
Listed as women's, though at 34mm it sits in the range that suits anyone.
