Abstract

Abstract This quartz crystal electronic watch eliminates watch parts formerly highly vulnerable to shock, but the quartz crystal assembly itself has high vulnerability to shock. This inventor determined that the quartz crystals resistance to shock is relatively high in all but one of its directions, and the cushioning effect of the watch''s external parts is relatively high in all but one of the directions, and he produced an overall highly shock-resistant watch by orienting the quartz crystal''s direction of maximum resistance to shock in the watch''s direction of least cushioning.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 205 words
Shock resistant wrist watch having upper and lower generally horizontal faces, said watch having a crystal over its upper face, strap fasteners at its far and near edges for securing a wristlet that will extend below the plane of its lower face, whereby said watch has high probability of some cushioning against impact when it falls in all solid angle orientations except the solid angle nearest the transverse horizontal axis, said watch having a quartz crystal frequency generator, said quartz crystal having its greatest dimension disposed substantially parallel to the watch''s transverse horizontal axis, and said quartz crystal being supported by fine resilient metal lead wires, said lead wires comprising arms and wrists angled relative to each other and both the arms and the wrists lying substantially in a plane perpendicular to the transverse horizontal axis of the watch, the arms being substantially parallel to each other, and the wrists meeting the quartz crystal substantially perpendicular to its opposite side faces and terminating in butt joints securing the wrists to said faces, the relative orientations of the recited parts being such that the least vulnerable orientation of the quartz crystal assembly coincides with that orientation of the watch that is externally least protected from shock.
Claim 2
Dependent Claim 205 words
Shock resistant wrist watch having upper and lower generally horizontal faces, said watch having a crystal over its upper face, strap fasteners at its far and near edges for securing a wristlet that will extend below the plane of its lower face, whereby said watch has high probability of some cushioning against impact when it falls in all solid angle orientations except the solid angle nearest the transverse horizontal axis, said watch having a quartz crystal frequency generator, said quartz crystal having its greatest dimension disposed substantially parallel to the watch''s transverse horizontal axis, and said quartz crystal being supported by fine resilient metal lead wires, said lead wires comprising arms and wrists angled relative to each other and both the arms and the wrists lying substantially in a plane perpendicular to the transverse horizontal axis of the watch, the arms being substantially parallel to each other, and the wrists meeting the quartz crystal substantially perpendicular to its opposite side faces and terminating in butt joints securing the wrists to said faces, the relative orientations of the recited parts being such that the least vulnerable orientation of the quartz crystal assembly coincides with that orientation of the watch that is externally least protected from shock.
