A 45.5mm round stainless steel case houses a blue gradient dial behind sapphire crystal with double-sided antireflective coating. The dial carries chronograph sub-dials with 30-minute and 1/10-second counters alongside ADD and SPLIT functions, a central 60-second hand, and a date display. Super-LumiNova is applied to both hands and indices. The case runs 12.8mm thick and takes a 22mm strap. The stainless steel bracelet fastens with a folding clasp incorporating a safety lock and diver extension. An anti-clockwise rotating bezel with an aluminium insert and 300m water resistance complete the dive watch credentials. The ETA G10.212 movement powers everything. At 180g, it sits with noticeable weight on the wrist.

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.
