Maritime nations were aware of the need for precise and dependable watches in order to determine the position of a ship at sea. Without precise timekeepers, long sea voyages were fraught with danger. After the 1707 shipwreck in the Isles of Scilly, in which an entire fleet of four vessels and the lives of over one thousand four hundred sailors were lost, the British Parliament ofered a “Longitude Prize”. Thus, a reward was to be given to anyone who found a dependable and efective method of determining longitude at sea. Many took up the challenge, among them John Harrison (1693 – 1776), John Arnold (1736 – 1799), Thomas Earnshaw (1749 – 1829) and Thomas Mudge (1715 – 1794) in England. Mudge constructed the first watch with a lever escapement, which would later be universally adopted. Frenchman Pierre Le Roy (1717 – 1785), who in 1748 invented the detent escapement used in modern chronometers, and Neuchâtel native Ferdinand Berthoud (1727 – 1807) also carried out research that would contribute to the development of a veritable industry. The timepieces in this chapter are arranged according to type: for example, pocket and deck chronometers and wrist chronometers, as well as by their type of escapement (spring detent escapement, pivoted detent escapement, lever escapement). By the late 18th century, timing contests had begun to be held, in which marine, ship, and pocket chronometers were scientifically examined in specialised laboratories and astronomical observatories. The timepieces were issued a Bulletin de marche (Rating- certificate) and the most precise among them received prizes and special mentions. These included the “record de pièce” that was awarded to the pieces that obtained the best results ever achieved at the Geneva Observatory. Patek Philippe watches took part in these national and international contests, achieving remarkable results.

  • Multi-Facetted Sundials
    The Scientific Tourist: Aberdeen Multi-facetted sundials Scotland is rich in multi-facetted sundials, singularly rich in fact. One is hard pressed to find two the same. As well as being individual in appearance, each one combines an appreciation of science, mathematics, high skill in stonemasonry, art and spectacle in a single object. Besides all of that, most of them are remarkably old, dating from between 1625 and 1725 in round numbers. They are mainly found in the gardens of venerable country houses, sometimes castles, or if they have been moved then they come from old country estates. These dials have usually outlasted the original houses of the aristocracy who commissioned them. A good many are described and some illustrated in Mrs Gatty’s famous book of sundials1 and more recently in Andrew Somerville’s account of The Ancient Sundials of Scotland2. The very top of the great sundial at Glamis Castle, from an illustration by Mrs Their widespread occurrence over Scotland attests to the fact that Gatty they were fashionable for about a century but, curiously enough, we don’t know why that was so. Were they just ‘fun’ to have in the garden, effectively a pillar with multiple clock faces on it, sometimes more than 50? Each dial is quite small so they aren’t precision instruments but people didn’t worry overmuch about the exact time of day in 1700. Were they a symbolic representation of ‘Science’ in the garden, a centre-piece and statement in a formal garden, just as later in the 18th century one may have found an orrery in the library

Escapement mechanism is a device designed to maintain a constant average speed of the escape wheel, by allowing it to rotate to the desired angle at certain impulse of time. While doing that it simultaneously support the oscillations of the pendulum or balance spring, by compensating for friction losses and air resistance. 7 century long history of escapement mechanisms, from 13th century verge mechanism up to modern-day escapements that can be found in luxury watches, will be shortly presented. Through lives of famous clockmakers and their achievements in field of making escapement mechanism will be given a new insight in science of time keeping - horology.
