Stepping up in the same colour and case shape
The Seastar name comes from the 1,000-foot depth rating the whole family shares, and this two-tone 40mm quartz variant sits at the more dressed end of that range. The rose gold PVD runs through the case and bracelet consistently — not a contrast piece but a coordinated one — and at 9.9mm thick it wears considerably flatter than the depth rating might suggest, sitting under a cuff where most 300m-rated divers will not. The coin-edge unidirectional bezel and screw-down crown with its guard are functional commitments rather than decoration, and the plongeur hands carry enough Super-LumiNova to read clearly in poor conditions. The quick-change system at the lugs means the bracelet can be swapped without tools, and the EOL function in the F06.412 movement signals battery depletion before the watch stops — a small practical advantage that most quartz movements at this level do not include.

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.
Cheapest place to buy
Both Goldsmiths and Mappin & Webb list it at £465, so choose on delivery and warranty rather than price.
