Powermatic 80 and Nivachron: what Tissot’s movement offers.

The Powermatic 80 is Tissot’s automatic movement, and its headline feature is an 80-hour power reserve, which keeps the watch running over a weekend off the wrist. Many versions add a Nivachron balance spring, an alloy hairspring that Tissot lists as resistant to magnetism and temperature changes.

What 80 hours means.

A fully wound watch with an 80-hour reserve runs for more than three days off the wrist, so a Friday-to-Monday break does not stop it. See power reserve explained.

What Nivachron does.

A balance spring regulates the beat of a mechanical watch. Tissot describes the Nivachron spring as patented and resistant to magnetism and temperature, which helps the watch keep better time in daily life. See our magnetism guide.

Which watches use it.

Is it worth the premium?

If you rotate watches or want less fuss, the long reserve is a real benefit. If you wear one watch daily, the reserve matters less. Our best Tissot watches list shows where each sits.
