PENDULE MYSTERIEUSE 'ZODIAC'
Swiss. Made circa 1960.
Fine and very unusual, 8-day going, gilt-brass mystery clock.
Oval polished gilt-brass base with two upright rings supporting
the clock, pivoted arm in the center with cylindrical
drums, one containing the movement, the other for the
hour pointer, ball feet.
Brushed gilt chapter ring with half and quarter-hour
divisions, applied patinated zodiac symbols for the hour
markers. Hour pointer on one end of the pivoted arm.
Nickel, half-plate, 15 jewels, straight line lever escapement,
monometallic balance, self-compensating flat balance
spring, index regulator, the reverse with a semi-circular
WEIGHT with hour-setting disc visible through a glazed aperture
in the case.
DIM. 23.5 x 21.5 x 15.5 cm.
This unusual clock is powered by an ingenious
system whereby a weighted rotor on
the back of the movement in the larger end
of the rotating arm turns gradually as the
hours pass, the slight change in position of
the WEIGHT causes the arm to rotate.
