Top quality cylinder movement of unusual construction, circa 1763.
Capped fullplate fusee movement of typical Mudge / late Graham caliper, with beautifully engraved cock and slide plate, having adjacent winding and regulation squares, the cap signed for Mudge & Dutton and, amusingly, scratch numbered 609 (crossed out) and 619. Cylinder escapement with 13 tooth brass escape, retaining the original Graham-type banking. Steel balance, blued-steel balance spring. Later enlarged, the replaced brass edge with enamel dial of circa 1825 - an indication of a long working life. 38.5 mm diameter, 15.5 mm deep, not including centre arbor.
Thomas Mudge & William Dutton, Fleet St, London, the foremost watchmaking partnership in the second half of the 18th century, both having been apprenticed to George Graham. This is one of a few smaller sized movements signed for Mudge that have caps signed for Mudge & Dutton. These date from when the close association between the two became a formal partnership around 1760.
NB: This movement is particularly noteworthy as it is among the first cylinder watches to discard the standard 'worm & wheel' set-up of the mainspring, using a ratchet and pawl mounted on the dial side of the pillar plate instead.
Dial with hair cracks and lacking hands, otherwise a rare chance to own an example of this makers work in better and more original condition than usually found, and manufactured when Mudge was still part of the partnership - due to illness, Mudge retired to live with his brother John, a doctor, in Plymouth in 1770. Not cleaned by me but tries tick when wound. Sold as needing at least a service and fresh oil in order to work properly.
