Stepping up in the same colour and case shape
The Seastar name derives from the collection's 1,000-foot depth rating — 300 metres — and the 40mm case sits at the middle of a family that runs from 36mm to 45.5mm, intended for those who actually use the water resistance rather than simply own it. Screw-down crown, protected by a guard, and a unidirectional coin-edge bezel are the working details; the ETA F06.412 Precidrive movement holds to within ten seconds a year and signals a dying battery before it becomes a problem on a dive trip. At roughly 10mm thick, this reads as a proper diver that will still pass under a cuff. The all-black PVD treatment — case, bracelet and bezel unified — kills any reflection in low visibility, and the sunray-brushed dial with plongeur hands picks up Super-LumiNova to read clearly when depth removes the colour from everything else. At 134 grams on a steel bracelet it has the weight of something that means business without becoming a chore on a long day.

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 300m it is rated for swimming, snorkelling and recreational 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?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWhat size strap does it take?
20mm. 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 men's, though at 40mm it sits in the range that suits anyone.
