Our take on the Tissot Sideral S Powermatic 80 Men's Watch

The Tissot Sideral S Powermatic 80 is a sport automatic in a 41 mm tonneau-shaped case, mixing forged carbon with stainless steel and pairing it with a rubber strap. It runs on the Powermatic 80 movement with an 80-hour reserve and a Nivachron balance spring for magnetic resistance, and it is rated to 300 m with a sapphire crystal. A regatta gauge on the dial points it at sailing and nautical racing. At $439 at Jomashop as of November 7, 2026, it sits well below what a Swiss automatic with these specs usually costs.

Best forSailing and regatta fans who want a regatta gauge on the dialBuyers wanting a Swiss automatic diver-rated watch under $500People who like bold tonneau cases and forged carbonWearers who swap straps often, thanks to quick release
Pros
  • 80-hour power reserve means it keeps running through a weekend off the wrist
  • Nivachron balance spring resists magnetism from phones, laptops and speakers
  • 300 m water resistance suits swimming and water sports
  • Sapphire crystal resists scratches
  • Quick-release rubber strap is easy to change
  • Forged carbon and steel case stands out from plain steel divers
Cons
  • 14 mm thick and 46.5 mm lug-to-lug, so it wears large on smaller wrists
  • Regatta gauge is a niche feature most buyers will never use
  • Rubber strap only; no bracelet option in the box
  • Forged carbon patterning varies from watch to watch, so no two look identical

Questions and answers

Is the Tissot Sideral S a good everyday watch?
Yes, if you like a large sport watch. It has a date, sapphire crystal, 300 m water resistance and an 80-hour automatic movement, so it handles daily wear and swimming.
How does it compare with the standard Tissot Seastar?
The Sideral S has a tonneau forged carbon case and a regatta gauge; the Seastar is a round steel diver. Both are 300 m automatics, but the Sideral S is the more distinctive, less conventional pick.
How big does it wear?
The case is 41 mm wide but 14 mm thick with a 46.5 mm lug-to-lug, so it wears larger than a 41 mm round diver. Try it on if you have wrists under about 6.5 inches.
Do I need to wind it?
No, it is automatic and winds from wrist movement. The 80-hour reserve keeps it running for over three days off the wrist.
What comes in the box?
The watch on its black rubber strap with a buckle. The strap is quick release, so you can swap it without tools.
When is it cheapest?
Grey-market sellers like Jomashop usually undercut authorized dealers. The best new price was $439 at Jomashop as of November 7, 2026.
