Vintage British Admiralty Pattern No. 810 Maritime Plotting Table Clock

What a fantastic Vintage British Admiralty Pattern No. 810 Maritime Plotting Table Clock, a real piece of history! As you would expect with anything made for the Royal Navy, this plotting table log clock as been very well engineered. It was made in about the 1940s.

The dial is marked ADY.PATT No. 810, which translates as Admiralty Pattern No. 810, and it was made by Colborne of Trowbridge, No. 898. The case is metal covered brass, with a hinged bezel holding a glass lid in place via a strong metal clip.

The clock is in very good vintage condition with no cracks or restoration. The dial has some loss of surface paint commensurate with age. It is manually wound with a standard clock key and has a nice loud tick.

The dial also has two levers, the one on the right is a ‘fast-slow regulator’ and the other is a ‘hacking’ lever which stops and restarts the clock movement.

The back of the clock case is made from bakelite and is marked with the recommended contacts to use with different plotting table logs: Forbes, Pitometer, and Chernikeef. In this case the ‘log’ is a device trailed from a ship to determine its speed through the water.
