Very rare English rough movement made with American machinery, circa 1885.
Fullplate going-barrel hollow-back movement with indirect wind, and typically shaped cock foot, the pillar-plate numbered and bearing the companies conjoined stamp. Frame only, no train or escapement parts, but jeweling in place for the balance. 43 mm diameter, 9.5 mm deep, not including centre arbor.
Machine-made movement by the English Watch Co Limited, formed out of the bankrupt Anglo-American Watch Company, set up by Aaron Dennison in Birmingham, England, in 1874. The works manager was Charles Haseler who took out various English patents for the firm - their letter code is not yet understood.
NB: This was the first attempt at manufacturing watches on the American system, using old Tremont Watch Company machinery, in England. Though it initially failed (for lack of funds) it is thought the English Watch Company went on to manufacture about 200,000 watches. This is, however, the only rough movement known to have survived from that time.
Somewhat dusty, but generally cleaner than most rough movements.
