Top quality keyless free-sprung watch with up/down by this famous maker.
Heavy 18ct gold double-back crystal case hallmarked 1877, casemaker JM (John Martin, Islington). Typical Kullberg half-plate caliper with reverse fusee and knockout keyless work, the 18-size I.P (Joseph Preston) frame stamped with Kullberg's 1411 serial number, jewelled to the 3rd with cap jewels on balance (diamond), lever and escape, and with hard brass setting for the fusee. Single-roller detached lever escapement. Compensation balance, free-sprung blued-steel balance-spring with overcoil. Signed enamel dial with state-of-wind at 12, original blued-steel hands. 52.5 mm diameter and weighing just under 130 grams in total. Together with later retailers velvet and silk lined box.
Joseph Penlington, 3 St George's Crescent North, one of the premier Liverpool watch and chronometer makers of the period, known to have retailed both watch and box chronometers supplied by Kullberg.
Victor Kullberg, Liverpool Road, one of London’s most famous watch and chronometer manufacturers. Full details of those who worked on this watch can probably be found in the Kullberg record books held at London's Guildhall Library, in the manuscript department, though not all the records survive.
Dial with hair cracks in the sunk up/down bit and some general signs of wear, otherwise a very good example of Kullberg's work and the case with no previous dedication or engraving. Presently being serviced (photographed prior to cleaning, please note) and sold with my usual guarantee.
