I have some interest in the Seastar 2000, the 600 metre dive watch certified to ISO 6425 (2018) standards. The Reference T120.607.11.041.01 features a blue wave dial motif and black ceramic bezel insert, the darkish hue on the edge of the dial offers pretty good contrast, this diver has some chunkiness about it. The three link bracelet merges well with the case, the folding clasp with safety latch is a little dated.

One of the apprentices brought one in for me to look at, the helium valve ensures this is a professional dive watch suitable for commercial mixed gas diving with stints in the recompression chamber and/or saturation bell. The 46 mm stainless 316L steel case is big, the crown protector is integral with the case and sits well with the largish crown. The large baton hands offer plenty of lume, the second hand with lollypop really works well, the round applied index markers offer a stylish dive watch.

The Powermatic 80 can be viewed through the display caseback, this is a proven automatic movement based on the ETA 2824-2 architecture with Tissot upgrades. The 80 hour power reserve is now becoming de rigeur with Tissot, this long power reserve comes with some limitations with 21,600 vph. The Nivachron balance spring offers plenty of magnetic resistance, this is a titanium-based alloy that is exclusive for Swatch Group brands. The Seastar Reference T120.607.11.041.01 offers plenty to the wearer and I can see why this is a popular diver.
