Stepping up in the same colour and case shape
The Supersport Chrono sits within Tissot's T-Sport collection, a line built around legible, tool-oriented watches that carry a chronograph without ceremony. The case runs to 45.5mm but stays under 12mm thick, which keeps it from riding high on the wrist in the way that chunky sports chronographs often do. The ETA G10.212 powering it is a workhorse Swiss quartz calibre with an end-of-life indicator — the seconds hand begins skipping every few seconds when the battery is approaching exhaustion, so there is no silent failure. The black dial plays off the blue sub-dials neatly, and the fixed bezel carries an aluminium tachymeter ring that is genuinely usable rather than decorative. The textile strap is stitched in white at the perimeter and backed with embossed leather, which stops the fabric from feeling raw against the skin on a long day. Quick-release spring bars mean the strap comes off without tools, which matters more than it sounds on a watch that ships on fabric.

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.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
What size strap does it take?
22mm. 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 45.50mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's.
