TRAVELLING CLOCK ROBERT Ca. 1810 Switzerland
The spring-driven, eight day movement consists of going, striking and alarm trains. The going train has a chain fusee and chronometer escapement with balance and regulation on a horizontal platform. On every quarter-hour the grande sonnerie striking train indicates the hours first, followed by the quarter-hours on two gongs. The clock also has trip repeat. The alarm is activated by pulling a chord, which winds a spring. The alarm train is set by a sweep central pointer on the chapter ring. The gongs are situated at the back, as well as the winding arbors and regulation.
The white enamel dial dominates the, the 4 winding holes emphasize the functions of the clock. The time is indicated by a pair of blued-steel Breguet hands on a black Arabic chapter ring with five-minute and minute divisions. There is also a blued-steel alarm hand and a counterbalanced central sweep seconds hand. The dial is signed by the maker above the 6: Robert. The dial is protected by a convex glass set in an engine-turned bezel.
The austere rectangular mahogany-veneered case has a slide at the back to access the movement. The clock is surmounted a gilt-brass carrying handle in the shape of two snakes with intertwined tails. Beneath the dial is a winding hole for the going train. There is a circular window set in an engine-turned surround, through which the escapement is visible. The clock stands on four gilt-brass claw feet.
