Tissot Gentleman Powermatic 80 Silicium Watch. Details that count: the understated exterior of the Gentleman collection hides the innovation at the heart of the automatic range. The Powermatic 80 movement is even more precise thanks to its silicon balance spring that offers additional resistance to the magnetic fields we encounter in everyday life. Open Heart models in the collection use innovative Nivachron balance springs to the same effect. With 80 hours of power reserve, it’s a movement that can keep pace with busy lifestyles. These Gentleman models are truly an impressive offering.
