Silicium
The word on the dial is the point. The 80.811 caliber uses a silicon hairspring instead of a steel one. Silicon is not magnetic, so the watch shrugs off the laptop, the phone case and the speaker that would send a steel-sprung movement running fast.
It is a functional upgrade rather than a cosmetic one, and it is rare at this price. The rest of the movement is the Powermatic 80 formula: 21,600 vibrations per hour and an 80-hour reserve, visible through a sapphire caseback.
Dress-sport
The dial is a deep blue sunburst with lumed baton markers, dauphine hands and a date at three. The case is 40mm and 11.5mm thick in 316L steel, with a domed anti-reflective sapphire and a bracelet on a butterfly clasp. Tissot rates it at 100m.
That combination is what makes it a dress-sport watch. Under a shirt cuff it reads as a dress watch. In the pool it is rated like a sports watch. Tissot’s figures are the ones printed here; nothing has been measured for this page.
Weight and wear
On the bracelet it weighs 164g, which is solid. The 21mm lug width is unusual and limits aftermarket straps, though the bracelet is the reason to buy this reference over the leather versions.
Super-LumiNova on the hands and markers means it reads at night, which most dress watches do not.

Verdict
The rare sub-four-figure Swiss automatic with a silicon hairspring, 80 hours and 100m, in a case that goes anywhere.
Strengths
- Silicon hairspring gives real resistance to magnetism
- 80-hour Powermatic 80 reserve
- 100m water resistance on a watch that suits a suit
- Domed anti-reflective sapphire and lumed dial
Trade-offs
- 164g on the bracelet is heavy for a dress watch
- 21mm lugs limit strap choice
- 21,600 vph is a slower beat than a 4 Hz movement
- Not a dive watch; 100m is the ceiling
Buy it if
Someone buying one automatic to wear every day, in the office and at the beach, with as little maintenance as possible.
Skip it if
You want a light watch, a leather strap as standard, or a proper dive rating.
FAQ
It refers to the silicon hairspring in the Powermatic 80.811 movement. Silicon is non-magnetic, so the watch resists magnetic fields far better than one with a conventional steel hairspring.
