Description: | Marine chronometer numbered 6045 by T Russell & Son and 156 by W. B. Crisp. A two-day full-plate fusee movement. Four pillars, all fixed with blued steel screws. The fusee has stop-work and Harrison's maintaining power. Earnshaw-type spring-detent escapement. Compensation balance with helical balance spring.
Mounted in three-tier box, push-catch for lid and lock for upper half. Upper half has a strut limiting opening to 90 degrees. The box fittings are standard, with surface-mounted handles on the sides, brass gimbals and a ratchet winding key. The push-catch and lock are surrounded by shaped brass inserts. The top of the lid has a small shaped brass insert inscribed "Alfred" with a crown symbol. On the front of the upper half is a round ivory tablet inscribed "RUSSELL ? CRISP 6045 2 DAY" and on the front of the lower half is a round ivory tablet inscribed "No. 6045". The base of the box is covered with green baize.
Silvered brass dial with Roman numerals and a large seconds dial having Arabic ten-second figures. An up-and-down dial is present under the XII position with the word 'Wind' replacing the 24-hour marking. The dial is inscribed in the centre "T. Russell & Son Liverpool No. 6045 / W. B. Crisp London No. 156". The chronometer is in good condition.
One of a pair of chronometers (the other being Gardner 6972) that came from Queen Victoria?s yacht, Victoria and Albert III. They were brought to the Royal Observatory for safe keeping during the First World War. When King George V asked them back in 1930, Astronomer Royal Sir Frank Dyson quickly had them overhauled before they were returned. He noted their performance was ?quite satisfactory and up to the standard required for navigational chronometers in H.M. Navy?.
