KOCK BRUCE A |
A shock resistant watch of relatively few parts and consequent inexpensive construction employing a dumbbell balance freely pivoted on a staff with the only connection between the balance and the staff being a leaf spring. The entire gear train of the watch is arranged on two shafts and the minute and hour hands are both driven directly by an intermediate wheel. The entire watch is assembled without screws, nuts or bolts.
