Fine, handsome and unusual 18K gold pair case lever and fusee with auxilliary
compensation by Johnson, Liverpool, circa 1830.
Fancy engine turned gold dial with applied gold numerals and applied floral
decorations is various colors of gold. Engine turned case with case and chased
bezels and pendant, with slight pocket edge wear. The movement with a diamond cap jewel and "Liverpool
windows", large clear jewels in screwed settings.
This watch has an uncut balance but is fitted with a circular bimetallic strip
mounted under the balance which provides compensation for changes in temperature. Historically technically interesting.
The maker was obviously so proud of this device that it has a separate engraved gold indicator
plate.
