Rare movement with makers 'Improved Rolling Detached Lever' escapement, circa 1830.
Fullplate fusee movement, both cap and movement signed, the cap with makers 'cross' stamp. Single-roller detached lever escapement, the roller of Brookhouse's design with a pivoted steel roller - see my drawing of the escapement. Under-sprung steel balance, spiral balance-spring. One-piece cream enamel dial with bold Roman hour numerals. 44.5 mm diameter, 13.5 mm deep, not including centre arbor.
Joseph Brookhouse & Tunnicliff, Derby, retailers of interesting skeleton clocks and this rare variant of lever watch, a reinvention of the pivoted roller first used by Pendleton in the later examples of the short series of watches he made for Josiah Emery at the end of the 18th century. See also David Penney Postal Auction catalogue No 2, February 2000, lot 31 for a similar movement.
