The cresting displays a bust of Mercury crossed by twin cornucopiae, supported by hippocampi with entwined tails, all above a bracket section with anthemion terminal. The polished brass pendulum swings just below the dial. The fine gilding is well aged and mellow, but probably not all original. The fine pierced brass hands appear to be original and were probably gilded at one time. Hedstrom's five pillar brass movement is of the English style but without fusees, is of eight day duration with hourly rack striking and half hour single strike, and has strike repeating via the cord on the front of the case.
Escapement is anchor recoil with silk suspension.
The winding barrel clicks use a single spring pinned to the front movement plate. Movement, dial and case are an original combination. Ephraim Hedstrom of Stockholm is recorded by Baillie as being born in 1775 and dying in 1816. He would have completed an apprenticeship and been eligible to practice under his own name by 1797.
