Power reserve is the time that a fully wound mechanical watch runs to a stop: typically 38 to 42 hours. The Powermatic 80 caliber allows the power reserve to be up to 80 hours. So you can leave this watch on for up to three days before you have to reset it...if you can last that long without it.
At the heart of this model beats a Powermatic caliber with a completely new Nivachron hairspring. This innovative material has been developed to offer greater resistance against magnetic fields. In addition, thanks to its titanium base, this Swiss-made hairspring is extraordinarily resistant to both thermal variations and shock.
