A rare table regulator by James Brock who was instrumental in the development and manufacture of the great clock at Westminster while he was foreman at Dent.

Elegant gilded brass decorative case with very thick bevelled glass panels and adjustable feet for precise levelling.

Clocks by James Brock are very rare and examples of his work are held by the British Museum and the Houses of Parliament. This exceptional table regulator is the only currently known example and was possibly made for one of the Great Exhibitions.

The signed circular plated movement has 4 tapered pillars, delicate wheel work and an external escape wheel running in jewelled bearings. It is of 8 days duration with a spring barrel and chain fusee, Harrison’s maintaining power and dead beat escapement with jewelled pallets.

The Dent style pendulum is a steel jar with mercury compensation and is threaded for coarse regulation. There is also rise and fall fine regulation actuated by a small winding square at the top of the main dial.

The brass silvered dial has central hour and minute hands with an inset sub dial showing seconds at 12 ‘o’ clock, it is signed Brock.64, George St Portman Sq London.
