Description

A very rare early 19th Century English patent Tic Tac escapement gilt pair cased watch.  Full plate gilt keywind fusee movement with dust cover.  Chased and engraved bell shaped cock with garnet endstone, blue steel Bosley regulator, plain three arm polished steel balance with gold spiral hairspring. Very rare patent Tic Tac escapement, thirty tooth escape wheel acting on a jewelled roller on the balance staff.   A slot in the roller simply allows the balance to be given impulse in one direction as it passes the tip of the tooth, escape pivots with endstones.  Flat white enamel dial with subsidiary seconds, Roman numerals, blue steel seconds hand with gold arbor, fine gold hands with heart shaped ends.  Gilt metal pair cases, oval pendant and bow.

A very rare watch in excellent overall condition.  This is the first pocket watch we have seen with this form of escapement.  It is stamped under the dial and cock “Marsh & Co  –  106  –  Patentees”.  Thomas Marsh, son of Anthony, apprenticed 1770.  Watch with his escapement in the Science Museum, South Kensington, patented in 1811.
