Abstract
Abstract A watch having a crystal controlled watch movement mounted in a watch case is provided with a crystal oscillator circuit, internal manually operative oscillator circuit adjustment means located on the underside of the watch movement adjacent the bottom wall of the watch case, visual time display means, and manually operative internal display adjustment means also located on the underside of the watch movement adjacent the bottom wall of the watch case. The bottom wall of the watch case is provided with external manually operated means connected to the internal display adjustment means for changing the time displayed by the display means, and is also provided with removable access means for providing access to the internal oscillator circuit adjustment means for fine tuning the frequency of oscillation of said oscillator circuit.

Claim 1
Independent Claim
206 words
In an electronic watch comprising a crystal controlled watch movement mounted in a watch case; said watch movement having a crystal controlled oscillator circuit, manually operative internal oscillator circuit adjustment means for fine tuning the frequency of oscillation of the oscillator circuit, visual time display means, and manually operative internal display adjustment means for changing the time displayed by said display means; said watch case having a generally tubular side wall, a generally transparent top wall, a generally circular bottom wall, and exterior manually operated means mounted on the case and connected to said internal display adjustment means; the improvement which comprises: internal display adjustment means located on the underside of the watch movement adjacent the bottom wall of the watch case, exterior manually operated means mounted on the bottom wall of the watch case and connected to the internal display adjustment means for changing the time displayed by said display means. internal oscillator circuit adjustment means located on the underside of the watch movement adjacent the bottom wall of the watch case, and access means mounted on the Bottom wall of the watch case for providing access to the internal oscillator circuit adjustment means for fine tuning the frequency of oscillation of said oscillator circuit.
Claim 2
Dependent Claim
206 words
In an electronic watch comprising a crystal controlled watch movement mounted in a watch case; said watch movement having a crystal controlled oscillator circuit, manually operative internal oscillator circuit adjustment means for fine tuning the frequency of oscillation of the oscillator circuit, visual time display means, and manually operative internal display adjustment means for changing the time displayed by said display means; said watch case having a generally tubular side wall, a generally transparent top wall, a generally circular bottom wall, and exterior manually operated means mounted on the case and connected to said internal display adjustment means; the improvement which comprises: internal display adjustment means located on the underside of the watch movement adjacent the bottom wall of the watch case, exterior manually operated means mounted on the bottom wall of the watch case and connected to the internal display adjustment means for changing the time displayed by said display means. internal oscillator circuit adjustment means located on the underside of the watch movement adjacent the bottom wall of the watch case, and access means mounted on the Bottom wall of the watch case for providing access to the internal oscillator circuit adjustment means for fine tuning the frequency of oscillation of said oscillator circuit.
Claim 3
Dependent Claim
83 words
