Harrisons First Chronometer
This photograph shows Harrison's first chronometer, developed between 1729 and 1735 in response to the British Government offer of a 20, 000 prize to anyone who could solve the problem of an accurate marine timepiece to aid navigation. Harrison did not win the prize with this chronometer, but he claimed the prize in 1761 with his fourth chronometer. To win the prize the timepiece had to be within 30 miles of the truth, in terms of longitude-time, on an actual voyage to the West Indies. This photograph is used in an advertisement for Tampimex Oil, a London-based oil broker. Photograph by Heinz Zinra"
