Lot 222

Swiss, 125 x 135 mm, circa 1830
A technically sophisticated hour repeating table clock with the rare one tooth lever escapement of Mac Dowal, here in a variant of Deshayes, and half hour / hour self strike, alarm and digital calendar
Case: birch burl, maple. Dial: silvered. Movm.: circular brass full plate movement, 2 hammers / 1 bell, 3 barrels, three-arm brass balance.
Inside the dial ring the workings of this unusual escapement are fully visible: the brass balance is located in the lower part, the seconds indication in the shape of a silver wheel sits above. Between them is the lever, which has a disc cut by two quarters instead of pallets; in the disk a small off-centred roller goes round in circles every half second. The striking construction is difficult to describe but very interesting to watch - this timepiece is certainly all the more attractive for showing off its technology so openly.
