Our take on the Tissot Seastar 1000 Powermatic 80 Silicium (T120.407.17.041.01)

The Seastar 1000 Powermatic 80 Silicium is Tissot's dive watch with a silicon balance spring, a feature usually reserved for far more expensive watches. The silicon hairspring resists magnetism and temperature swings, and the Powermatic 80 movement runs for about 80 hours on a full wind. The 300 m rating, screw-down crown and sapphire crystal make it a genuine dive watch, not just a dive-style one. It suits buyers who want Swiss automatic specs without paying luxury-brand money, though it is a chunky, heavy watch on the wrist.

Questions and answers

Is the silicon hairspring worth it?
Yes, if you care about magnetic resistance. Silicon is immune to magnetism and less affected by temperature, which keeps timekeeping steadier around phones, laptops and magnets. Most divers at this level use a standard alloy hairspring.
How does it compare with the standard Seastar 1000 Powermatic 80?
The main difference is the silicon balance spring, which adds magnetic and temperature resistance. Case, dial, water resistance and the 80-hour movement are otherwise closely related.
Can I swim and dive with it?
Yes. It is rated to 300 m with a screw-down crown, so swimming, snorkeling and recreational diving are fine. Rinse it in fresh water after salt water use.
How long does it run without winding?
About 80 hours on a full wind, so it keeps running through a weekend off the wrist. Wear it daily and your wrist motion keeps it wound.
Is the strap easy to change?
The watch uses standard lugs, so most 21 mm straps fit. Swapping to a steel bracelet or rubber strap is straightforward with a spring bar tool.
Does it fit smaller wrists?
It is a large dive watch with a thick case, so it wears big. Try it on if your wrist is under about 7 inches, or consider a smaller diver.
Where is the Tissot Seastar 1000 Powermatic 80 Silicium (T120.407.17.041.01) cheapest?
