The Tissot Seastar 2000 Professional has performance in its name. The new power diver’s watch offers water resistance to depths of 2000 feet, or 600 meters. Find out all the other details here in my exclusive test for the market launch!

Tissot thinks highly of its new diver

When I first read the press release that Tissot sent out on the occasion of its new diving watch flagship, I was amazed. Because what the manufacturer, which belongs to the Swatch Group, advertised there had about as much to do with nice fashion watches in interchangeable diver optics as a fast food burger has to do with healthy nutrition. Exactly, nothing at all. According to Tissot’s promise, the Seastar 2000 Professional would be a true power watch. The performance athlete among diving watches, a progressive timepiece with groundbreaking technologies on the pulse of time.

You want a little taste? On paper, the Tissot Seastar 2000 Professional is a certified diver’s watch according to ISO standard 6425, equipped with a helium valve, above-average water resistance and materials that are insensitive to magnetism. Everything you need for professional diving. As I said, the name says it all. And if these values alone weren’t enough to convince me, I was equally taken with the first press photos that Tissot provided right away. A timeless design, not obsessively modern or retro, and also distinctly maritime and tasteful. 

Promises kept – at least at first glance

But I should not judge too early. And so it was clear: a test had to be made. For this purpose, Tissot kindly provided me with the model with the reference number T120.607.11.041.00 in advance, which is now unpacked and lying on the table in front of me. One thing I see immediately: the photos did not lie. The Tissot Seastar 2000 Professional is a large and bulky timepiece that can be identified as a true diver’s watch at first glance. After all, it features a wide stainless steel case and an easy-to-read dial with dot-shaped indices framed by a true diver’s bezel. Tissot itself describes the appearance of its new flagship diver’s watch as “masculine,” which I think fits really well.

What is new is the color scheme of the dial, which has changed quite a bit after all and now delights with its maritime flair. The gradient has stayed the same compared to the Seastar 1000, yeah. But the blue tone is much brighter and fresher. Moreover, a wave-like pattern loosens up the overall look and makes the big diver a charming companion on the wrist.

The Tissot Seastar 2000 Professional on the wrist

46 millimeters in width, 16.25 millimeters in height. These are the dimensions that a Tissot Seastar 2000 Professional works with. As soon as you flip the watch over, this becomes visible on the wrist as well. So it certainly doesn’t hurt if you prefer larger watches anyway. A case that is over 16 millimeters thick sounds enormous at first. But if you put these dimensions in relation to the diameter, the Seastar 2000 Professional looks quite sporty and extremely well proportioned.

The design of the watch has the decisive advantage that it makes it flexible to use. It is sporty and functional, yet not too technical. With the elegance that is definitely present, you can wear the watch to any occasion, be it at a business lunch, in the office, at the pool or with a wetsuit. The Tissot Seastar 2000 Professional is an everyday diver’s watch that the modern man can wear both at work and for recreational sports! 

A case that sets the benchmark

The greatest strengths of the Tissot Seastar 2000 Professional lie in its case. This is made of 316L stainless steel, whose robust properties prevent any corrosion, so you can wear the watch for years without hesitation. The stainless steel surfaces are partly satin and partly polished. Lightly recessed surfaces on the sides give the timepiece even more sportiness. The six-screw case back is equipped with a circular viewing window made of sapphire crystal, through which you can admire the automatic movement inside the watch. A sympathetic detail: the seahorse imprint. By the way, the level of workmanship is as you would expect from a Swiss premium watch – very high.

Sapphire was also used for the crystal. It is stable, protrudes slightly and anti-reflective on one side for better readability. Thanks to its curved shape, solid case walls and case back, the Tissot Seastar 2000 Professional achieves a water resistance of up to an above-average 60 bar. So that makes 600 meters – or 2000 feet, which explains the Seastar’s name. Compared to the Seastar 1000, this is yet another considerable increase. The new model now dives twice as deep and thus complies with ISO standard 6425.

The Tissot Seastar 2000 lives up to the ‘Professional’ label

On the side, you’ll find the screw-down winding crown surrounded by an angular crown protector that prevents damage on dives. Thanks to its size matching the dimensions of the Tissot Seastar 2000 Professional and the fluting on the side, it’s quite easy and pleasant to pull out and turn the crown. I didn’t have any problems, anyway.

Even more interesting, however, is the other side, where at the latest now everyone should understand why the Tissot Seastar 2000 has deserved its name suffix ‘Professional’. At 9 o’clock, you find a helium valve. It is necessary if you want to wear and use the watch at depths deeper than 100 meters. Helium molecules are so small that they can penetrate through the seals of the diver’s watch into the interior of the case. During decompression (the pressure drop when surfacing), they cannot escape fast enough, so that even a stainless steel case can burst due to the overpressure. To avoid this, the diver opens the valve so that the gas can escape. In my opinion, this is an important function that ambitious divers should not do without!

Prepared against magnetism – the movement

Inside the case of the Tissot Seastar 2000 Professional works an automatic caliber. This is a Powermatic 80, which is also used by other brands of the Swatch Group such as Mido, Hamilton or Certina. With a very enduring 80-hour power reserve, the Powermatic 80 outperforms many diver’s watches by twice that amount and is technically on the cutting edge. It also impresses with its precise accuracy as well as longevity. The functions of the caliber, hour, minute, second and date are sufficient for everyday life and diving. It doesn’t need more than that.

However, the power reserve is not the only innovative feature of the movement. In keeping with Tissot’s own slogan, “Innovator by tradition,” the movement was made by the Swiss manufacturer primarily with components made of magnetically insensitive metals. Magnetism is considered one of the greatest dangers to watch movements. It can throw the caliber out of sync and, in the worst case, seriously damage it. Thus, there is a new regulating spring in the movement, made with a titanium-based Nivachron alloy. Titanium is insensitive to magnetism. In the movement, the regulating spring ensures precise accuracy.

Dial, bezel and bracelet

The fresh cyan blue of the dial becomes darker towards the edge, eventually turning into a black tone, from which the rectangular applied date window at 6 o’clock stands out. On the dial with the engraved wave motif, the dot-shaped rhodium-plated indices are particularly easy to read. After all, functionality is what counts under water. This works especially well in the dark thanks to the coating with blue-radiating Swiss SuperLumiNova®. The hands are nickel-plated and also coated with luminous material.

I really like the black bezel, a real diver’s bezel that can only be turned counterclockwise. Its edge is fluted, so it can be operated even with thick diving gloves. The clicks engage cleanly and guarantee good haptic feedback. The inlay is made of lightweight ceramic, on which the Arabic numerals are neatly printed. 

Lastly, I would like to show you the bracelet. My Tissot Seastar 2000 Professional is equipped with an everyday wearable and timeless three-link stainless steel bracelet. The folding clasp with the engraved Tissot-T is thanks to the diver extension also geeeignet for the wetsuit. Alternatively, you can order the watch with a rubber strap, which is even more functional.

My conclusion about the Tissot Seastar 2000 Professional

The Tissot Seastar 2000 Professional is a diver’s watch, which is literally washed with all waters and could convince me optically as well as technically. Especially the technical innovations such as the anti-magnetic movement as well as a good choice of materials, a helium valve and the certification according to ISO standard 6425 make it clear that the Tissot Seastar 2000 Professional is a diver’s watch with pretensions and can do more than just please its wearer with its look.

However, the professional claim does not exclude the fun. And that is something you will definetly have with the Tissot Seastar 2000 Professional in any case. The masculine design does justice to the inner workings and convinces with functionality and sportiness. The playful wave motif and the classic stainless steel look ensure the necessary suitability for everyday use, which makes a good figure not only in the coral reef, but also at the meeting!
