The Bulova R333M watch movement, period 1972-, incorporates various functions including an electromechanically controlled balance motor, a sweep second hand, a hack feature, an adjustable stud holder, electronic components, shock protection, and a sweep seconds mechanism. With the aid of the hack mechanism, the watch ensures that the balance comes to a halt in a position that facilitates reliable restarting when the crown is pushed in. The movement, which is not self-starting, operates efficiently while incorporating these features.
