Stepping up in Tissot's range
The PRC 100 arrived in the mid-2000s as a sport watch with a strong visual character, and this 34mm version brings something the original lacked: a movement that never needs winding and almost never needs attention. The F06.615 uses photovoltaic cells hidden beneath the crystal in a honeycomb array to convert ambient light into stored energy, with enough surplus in a full accumulator to run for up to 14 months in complete darkness. When reserves finally drop low enough to matter, the second hand shifts to four-second jumps as a warning — a more useful alert than a watch that simply stops. The case itself is 316L steel under yellow gold PVD, and at 9.14mm thick it sits flatter on the wrist than the sport-watch category usually manages. The dodecagonal bezel gives the dial surround some visual structure without adding bulk, and the champagne dial with luminous gold-tone hands reads clearly across different light rather than committing to one register. At 97g on the bracelet — steel with the same gold PVD treatment — the weight is present but not heavy; this is a watch that holds its position on the wrist rather than riding light against it.

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.
