• The mahogany and mahogany veneered round-bottomed case has a lockable door at the bottom and two side doors for access to the pendulum.  
   
• Case height 17 inches, case diameter 14½ inches.
   
• The clock is signed on the 12-inch diameter silvered dial Dutton Fleet Street.
   
• The dial has an engraved number above the centre, now very worn with the last digit erased, probably the date 185x. Above the date something else has been erased, probably a cypher.
   
• The 4-pillar movement has rectangular plates, an anchor escapement and a single chain driven fusee.
   
• The front plate is numbered 1254 3 and the timepiece has blued steel hands.
   

An almost identical clock by Dutton dated 1852 with engraved Royal Cypher (both engraved on the dial) is illustrated in Victorian Clocks by Richard Good.

Robert William Dutton, a third generation clockmaker, was apprenticed to his father in 1825 and became a Freeman of the Clockmakers Company in 1833. Dutton is recorded as still being in business in 1856 and his grandfather - William Dutton - was apprenticed to George Graham and in partnership with Thomas Mudge for a number of years.
