Heavy 18ct gold crystal (flat glass) case, the inner cover engraved with Russell's 'Time-O-Day' trademark, hallmarked London 1892, casemaker EW (Edgar Wilkins, Clerkenwell). Kullberg’s unique half-plate reverse-fusee movement with 'knock out' keyless work and distinctive balance-bridge, jewelled to the centre with cap jewels on balance (diamond), lever and escape arbors, the 18-size frame stamped JP (Joseph Preston, Prescot). Double-roller detached lever escapement with inverted rollers, as often seen in best London work of this date. Compensation balance, free-sprung balance-spring with overcoil. Signed enamel dial with state-of-wind sector at 12 in perfect condition, with the original full set of blued-steel hands. 53.5 mm diameter and weighing 140 grams (just under 5 ounces) gross. Together with the original T R Russell velvet and silk lined box.
Thomas Russell, one of the largest and most important Liverpool watch manufacturers of the period, and also retailers of other English, Swiss and American made watches in the UK market; an interesting and convoluted history which is still to be properly recorded.
Victor Kullberg, one of London’s most famous watch and chronometer manufacturers who also supplied watches for others to retail. NB: Details of the production of this movement can be found in the Kullberg record books held in the Library of the Clockmakers Company, MS 14537/5, 18th July 1892.
Joseph Preston, the most famous of Liverpool watch rough movement manufacturers, supplier of this individual caliper to the Kullberg firm and no one else.
Showing almost no signs of age or use, the covers and bow still tight, and with no previous engraving to the case, this must rate as the finest surviving example of this unique Kullberg caliper. Shown with a suitable 18ct pocket-to-pocket chain, which is available if wanted. The watch, serviced some years ago now, will be freshly serviced for its new owner.
