George Morton, PATENT No 2432, October 1856, a form of Robin escapement in which the lever type action gives a chronometer type impulse at every other beat. Starting with Morton's Patent in 1856, these English watches developed a variety of styles and names, the 'London Patent' and 'Patent Chronometer' names used immediately before it became 'Patent Union.' For more information, see the British Museum Catalogue of Chronometers, page 270-273.

A few signs of age and wear, but generally in fine original condition, and a rare complete cased example of this unusual escapement, more so in that that it has neither lost its original case nor had the escapement altered to a standard lever, as very many have. Serviced and guaranteed.
