Three-quarter plate keyless movement, the top plate with raised barrel, the chronograph work mounted under the dial and the underside of the cock foot stamped ‘JS.S,’ a stamp I do not remember seeing before. Single-roller detached lever escapement with beautifully made solid gold lever, pallets and roller, the lever of ‘tuning fork’ pattern as often associated with the best quality work. Compensation balance, balance-spring with overcoil. Snap-on signed enamel dial with 60-minute register, of that lovely off-white WILLIS colour but unsigned, as is usual with these multi-sunk dials. 46 mm diameter, 10.5 mm deep, not including centre arbor.
Robert Milne ‘Chronometer and Watch Maker,’ working on the top floor of No 40 South Street Manchester, a fine watchmaker. Milne graduated with Honours in his 1883 BHI examination and was appointed as a ‘Maker to the Admiralty’ in 1901. He tended to specialise in Deck Watches, karrusels and obtaining ‘Especially Good’ Kew A results – his watches achieved the “best average” at Kew in 1903, followed by equally good results in the following years.
Lacking all hands, the dial with some fine hair cracks and some light corrosion of the steel index and stud, but not as bad as it looks in the images which accentuate the contrast. Otherwise complete and ticking happily when wound. The chronograph mechanism complete and also operating correctly.
