Rare two-train quarter repeating movement, ex Paul Chamberlain, circa 1890.
Three-quarter plate highly jewelled movement, with cap jewels on balance (diamond), lever and escape, the two-trains wound from a single button, winding in opposite directions. Single-roller detached lever escapement. Compensation balance, balance-spring with overcoil. Single-sunk enamel dial held in later(?) snap-on brass ring, with good set of what appear to be original matching gold hands. 46 mm diameter, 10 mm deep, not including centre arbor.
William Parkinson and William James Frodsham, 4 Change Alley, London, a famous firm of chronometer and watch makers - see the book on the various Frodsham firms by Vaudrey Mercer, a copy of which is usually available on my website.
Major Paul Mellen Chamberlain, one of the foremost watch collectors of the 20th century, author of the book It's About Time, a must for any serious watch collector. Chamberlain formed two distinct collections, the first being given to Michigan State University during the 1st World War, where much of it was unfortunately stolen in 1958. Surviving the war, Chamberlain started a second collection which, by the time of his death in 1940, amounted to over 1200 pieces. This movement, item No F11, is recorded in a list made of the collection, my copy of which is dated January 1939. It was dispersed after the Major's death by his widow Margaret.
Dial loose in its ring (watch glass cement would do), otherwise in good original and unbroken condition, complete with button and stem. Not cleaned by me but ticking, repeating and with the centre-seconds train, indicating dead seconds, working properly.
