The 6309 movement is a base movement with a rotor, the little thing that spins when the watch is in motion. It drives the mainspring which in turn drives the balance wheel. This drives the hands and the day/date mechanism. This movement has 17 jewels, tiny rubies that reduce friction within the system.Oct 3, 2006
