Vienna regulator movement with duplex escapement and pendulum
Record status
Individual type · partial
Period
Circa 1860
This Vienna regulator movement with pendulum dates to circa 1860 according to the auctioneer. Described as featuring a duplex escapement, maintaining power, shuttered plates, and central jewelling, the assembly is fronted by a 7-inch circular enamel dial.
The dial displays Roman hour numerals and an upper subsidiary seconds track, framed by an engine-turned brass bezel. Open-moon Breguet-style hands are fitted, though the condition report notes the seconds hand is missing. A suspension link and a long pendulum with a circular metal bob accompany the dial and movement assembly.

- Dial and Visual Presentation
- The lot consists of a movement assembly fronted by a 7-inch circular white enamel dial framed by an engine-turned surround. The dial displays Roman hour numerals and an upper subsidiary seconds track. Open-moon Breguet-style hands indicate the time, while the subsidiary seconds hand is noted as absent. Accompanying the movement and dial assembly in the catalogued image are a separate suspension hook and a pendulum fitted with a circular metal bob. A clock case, drive weights, and a winding key are not recorded as present in the auction description.
- Reported Movement Characteristics
- The auctioneer describes the item as an unusual Vienna regulator movement featuring a duplex escapement. Additional movement features reported by the saleroom include shuttered plates, jewelling to the centre, and maintaining power. The auction listing dates the clockwork to circa 1860. No specific maker, country, or workshop signature is reported in the catalogue text or visible on the front dial.
- Condition and Documentation Limits
- The seller's condition report describes the lot as 'in good condition though lacking seconds hand.' Mechanical operation, timekeeping accuracy, and the completeness of the internal gear trains are not detailed. Because the mechanism remains concealed behind the dial in the provided saleroom photograph, internal specifications such as the shuttered plate layout, central jewelling, maintaining power detent, and duplex escapement rely entirely on the auction house's description rather than visible confirmation.
