Masons Antiques has dated this piece to the 1860s.
The 8 day, twin train, pendulum movement by VINCNTI of PARIS strikes on the half-hour and the hour. The movement, dial, and pendulum all marked with the same serial number.

A silvered, engraved dial and chapter ring having black engraved Roman numerals. Complete with original keys. (Always a sign of a cherished item)

The movement has just been fully serviced by our BHI registered staff.
It is rare to find an antique of this quality and in this condition and would tend to suggest that it has been in the ownership of a single family from new.
