TISSOT Seastar 1000 Powermatic 80 DIVER

Tissot’s first water-resistant collection debuted in 1938 with the launch of the Tissot Camping collection. Water-resistant and dust-tight, thanks to a screw-down closing system, the watches were also equipped with a Stainless steel case and virtually unbreakable glass.

Tissot’s archives dating back to 1938 have information about their water-resistance tests which were conducted in collaboration with the Swiss laboratory for watchmaking research in Neuchâtel, Switzerland, outlining the extensive time and research that went into these pioneering experiments.

In 1954, the Tissot Seastar collection was launched. Highlights included the Tissot T12, launched in 1956 which was guaranteed to a depth of 120 meters, making it the ideal watch for SCUBA divers and fans of the ocean.

A few years later, the Tissot Seastar Seven marked a patent registered, more effective Monocoque system and a thinner, more elegant design for the watch as a whole. Today’s Tissot innovative water-resistant collections boasts almost 3 times the water-resistance.

The 2018 Tissot Seastar 1000 Powermatic 80 is powered by the ETA caliber of the same name with 25 jewels, a beat-rate of 21,600 vph and a power reserve of 80 hours. Its dial can be had in graduated blue, silver or black.

It has a guaranteed water-resistant to a depth of 300m and its 43mm Stainless steel case is fitted with a ceramic bezel and a Sapphire crystal while an exhibition case-back affords views of the Powermatic 80 caliber.

Thoughts? A pretty good-looking new collection, I don’t think I’m much of a fan of the font used for the Seastar text on the dial. How about you?



  1. Why 43 mm??? Why not just 40 mm

    1. Some brands think that bigger is better; but i'm with you 42 and below ... guess a submariner matches our style more :)

    2. Some of us have a 8 1\2 inch wrist and need\want the better size

  2. Looks better than the previous version. Neater and more grown up.

  3. 1) It's not so much the 43mm case but the lug-to-lug. Those lugs look a bit beyond 50mm. It'll wear too big.
    2) The dial refresh is actually very good. Although once I saw the Bvlgari diver the previous version of the Seastar had grown on me.

  4. just ordered one in blue dial...looks great...yes i would like a 40mm but 43 isn't out of the question...cant wait to see it

  5. It's thin (<13mm) so it should wear nicely, won't be top heavy.
