UNUSUAL TRAVELLING CLOCK Ca. 1830 France
UNUSUAL TRAVELLING CLOCK
with visible escapement ‘in the manner of Pons’
The spring-driven eight-day brass movement of this unusual travelling clock consists of going and striking trains. The going train has MacDowal single-pin escapement, a variation on that of Deshayes, with hairspring balance and regulation, which is constructed visibly on the dial. The striking train indicates the hours fully and the half hours with a single stroke on a bell. The clock has trip repeat, activated by pushing a button on the case. In addition, the clock has an alarm. The clock is wound on the front.
The circular gilt-brass dial has a silvered-brass chapter ring with black Roman hour numerals, five-minute and minute divisions. The time is indicated by a pair of blued-steel Breguet hands. Below the middle is the jewelled hairspring balance with regulator pin. The direction for the regulation is indicated by the letters R and A (retard – slower and advance – faster). Above the middle is a rotating silvered brass seconds ring. There are two apertures to the left and the right of the middle, the left one to set the alarm time (with a watch key) and the one on the right for indicating the date. The balance is flanked by the winding arbors. The dial is protected by a faceted glass, set in a gilt-brass bezel.
The birch-veneered case is embellished by maple-wood borders. The panel at the back can be opened with a catch, which gives access to the movement. The case is surmounted by a shaped gilt-brass carrying handle. The case rests on four gilt-brass bun feet.
