Abstract

A capacitor for the oscillator of a quartz regulated watch comprises electrodes with conducting bands (2, 3) insulated from each other and mounted on a plate support (1). The bands are on the same side of the plate support. They may be in the form of a circular or a square spiral. The conducting bands may have branches (4, 5) with the branches (4) of one conductor (2) being disposed between the branches (3) of the second conductor to form an inter-digital arrangement.
