Lovely pocket chronometer movement by this accomplished but now little known specialist, circa 1865.
Slim capped three-quarter plate movement jewelled to the third, of typical lever proportions, but finished as a chronometer, the 18-size Lancashire frame stamped T+S (working in Newton le Willows). Spring detent escapement with Earnshaw-type footed detent with gold passing-spring. Compensation balance, spiral balance-spring with unusual stud. Enamel dial and original blued-steel fleur-de-lys hands in fine condition. 46 mm diameter, 8.5 mm deep, not including centre arbor.
John Glover, 4 Swinton St, Grays Inn Rd, London 'chronometer escapement maker,' from a family of specialist chronometer workmen. Tony Mercer states that he was apprenticed to John Roger Arnold, though I cannot corroborate this. We do know all the Glover's spent some time in America where they gained a well deserved reputation. John's brother, Henry Glover, worked as a chronometer specialist, as did his father, also John, who had indeed been apprenticed to the famous John Arnold. John Glover 2-day box chronometers came 2nd in the 1854 and 4th in the 1863 Greenwich Trials.
NB: Robert Gardner, as recounted by Paul Chamberlain, described Arthur Paul Walsh as the 'prince of pocket chronometer makers,' a compliment that could equally be applied to John Glover I believe.
From the collection of the late Bradley Ross. In fine condition but with a broken locking jewel, the reason no doubt that the movement looks to be so little used. Not working but well worth restoration and of a size that should be far easier to find a suitable case.
