Transitional 3/4 plate watch (unrestored)
John Wood, Liverpool, circa 1823. Transitional 3/4 plate watches are full plate watches with the balance sunk below the surface of the plate and the cock flush with it, making a much thinner watch. All except one that I know of (only 11 including this one) have Massey escapements and are definitely dated between 1823 and 1830. This watch is very rare because it has centre sweep seconds; most have standard sub-seconds.
