Since it's not a quartz watch, SISTEM51 has no need for a battery — it's powered by the person who wears it. Every movement of the wrist sets the rotor in motion, winding the watch, so SISTEM51 features an 'automatic', or 'self-winding' movement. Even when laid to rest for a while, it keeps on going for an exceptional 90 hours.
