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.
