Power reserve is the time a fully wound mechanical watch runs until it stops - usually between 38 and 42 hours. The Powermatic 80 calibre makes a power reserve of up to 80 hours possible! So you can leave this watch for up to three days before having to set it anew - if you can do without it for that long...
The beating heart of this model is a Powermatic calibre with an entirely new balance spring made of Nivachron(TM). This innovative material has been developed to increase resistance to magnetic fields. The Swiss-Made balance spring has a titanium base and is therefore exceptionally resistant to temperature variations and incredibly shock-resistant.
