Tissot Luxury Lady Powermatic 80 Diamond Accents Automatic T086.207.22.116.00 T0862072211600 Women's Watch The Tissot Ballade runs on the Powermatic 80, a movement equipped with a patented, silicon-made balance spring. A classic piece taken to the next level; the silicon being non-magnetic and with better temperature sensitivity and shock-resistance than conventional metal, offers much better chronometric precision and stability where standard watches might falter. It also adds to the movement’s longevity and precision.
