Tissot Seastar 1000 Powermatic 80 — Blue Dial, Black Rubber Strap
The watch
Built around a blue dial, the Tissot Seastar 1000 Powermatic 80 pairs a 43mm case with a Powermatic 80 automatic movement. It brings 300m water resistance and a sapphire crystal. It belongs to Hour IV, Dive, in our Expedition season: a natural choice for water sports and everyday wear.
A blue gradient dial deepens from bright azure to near-black across this Seastar 1000, set in a 43mm brushed-and-polished steel case with a coin-edged ceramic bezel. Luminous hands and markers keep it legible from the surface to the sea floor.
The Swiss Powermatic 80 automatic winds from the motion of your wrist and holds around 80 hours of reserve, its rotor on show through the exhibition caseback.
Screw-down crown and caseback rate it to 300 meters, and the sporty black rubber dive strap wraps securely for swimming, boating and everyday wear.
For the water lover who wants Swiss refinement and ocean-ready color on a rugged rubber strap.
New, boxed and warrantied — ships within the US.
Good to know
It is a self-winding Swiss automatic movement powered by the motion of your wrist, with no battery required. Fully wound it holds roughly 80 hours of running reserve.
Yes. It is water resistant to 300 meters (30 ATM) with a screw-down crown, so it is rated for swimming, snorkeling and recreational scuba diving. Always make sure the crown is fully screwed down before entering the water.
The case measures 43mm — a bold size that suits larger wrists (roughly 17.5 cm / 6.9 in and up). Our watch size guide (/pages/watch-size-guide) explains how to measure your wrist.
It has a blue dial, framed by a unidirectional rotating dive bezel with ceramic insert bezel, under a sapphire crystal.
The unidirectional rotating dive bezel only turns one way so you can safely track elapsed time, while the scratch-resistant sapphire crystal keeps the dial clear and legible for years.

On the ChronoSeasons dial it sits at Hour IV — Dive, part of the Expedition season, and suits swimming, sailing, beach travel and everyday wear.

From the journal
Owners say
Ordered this sight unseen for weekend wear and was impressed by the weight of the 43mm case and the gloss on the ceramic bezel. Knocked off a star only because the screw-down crown threads are tight at first and take a firm push to catch.
300m resistance and a very comfortable black rubber strap. Wears great on my wrist.
Great blue dial on rubber. Swapping onto an aftermarket steel bracelet took 15 minutes with stubborn pins.
Thanks for the note, Logan! Glad you're enjoying the blue Seastar 1000.
The stock black rubber strap balances the 43mm steel head nicely, and I also swapped on a 21mm orange FKM dive strap for lake weekends. Only reason for 4 stars is the shipping carrier delayed the package by two days.
Sorry about the two-day carrier delay, Jordan! That blue gradient dial on an orange dive strap sounds like a great lake setup.
I wasn't sure if 43mm would overwhelm my wrist when ordering online. Because of the black outer vignette on the blue dial and the compact lugs, it wears more like a 41mm watch. The ceramic bezel and sapphire crystal feel rock solid.
Got this for my dad's 60th birthday before his fishing trip to Florida. He wanted a real Swiss dive watch on a rubber strap so he wouldn't scratch up a metal bracelet on the boat, and he loves the deep blue gradient dial.
The factory black rubber strap with the grid texture inside is very comfortable right out of the box on my wrist. Since it uses 21mm quick-release spring bars, I also picked up a navy sailcloth strap that matches the gradient blue dial.
