The precision table clock PADIRAC has a so called „Regulator face“, that means the indication of hours, minutes and seconds are separate. It has some unusual or neverseen features:
Two in series linked springs give a 4 months running time. The spring barrels are beared on one side only (cantilevered bearing) to let the big wheel with 24 hours digits turing in front of them.
The feet, the frame and the big wheel are out of acryl glass giving the clock an unusual transparent appearance.
A circular scale built in the front foot indicates the power reserve.
A twin pendulum with fused silica rods is directly linked with the anchor. It beats the half second and drives the thin second hand. A device lets the minute snap into its position according to the second hand.
All wheels are beared in miniature ball races, the smallest with ceramic balls.
Diamond coated pinions ensure lowest friction so that lubrification is superfluous.
