  • Century Regulator by John Roger Arnold Expert Adviser's Statement
    Case 5 2010-11 : An early 19 th -century regulator by John Roger Arnold Expert Adviser’s Statement EXECUTIVE SUMMARY 1. Brief Description of item • What is it ? Longcase regulator • What is it made of ? Mahogany, brass and steel. • What are its measurements ? Height 193 cms. • Who is the artist/maker and what are his/her dates? John Roger Arnold (1769 – 1843) • What date is the item? 1795 – 1800 • What condition is it in? Good and original. 2. Context • Provenance From the time of manufacture to the recent sale at Bonham’s London Auction House (15th December 2009), making an assumption of inheritance, the regulator has a traceable provenance – see appendix 3 below. • Key literary and exhibition references The regulator has not been exhibited and has not featured in any published work. 3. Waverley criteria • Which of the Waverley criteria does the item meet? (If it is of ‘outstanding significance for the study of some particular branch of art learning or history’ which area of art learning or history). Waverley Criteria1 and 3. • Very briefly why? Waverley Criterion 1– It is so connected with our history (including local history) and national life that its departure would be a misfortune. This regulator is important because it is intimately connected with the life and business of one of Britain’s internationally recognised and celebrated chronometer making businesses and with the history of precision timekeeping in this country - an area in which London clock, watch and chronometer makers lead the world for over a century. The Arnold business had a history of providing regulators of the highest quality to observatories, perhaps the most celebrated examples being two regulators commissioned from John Arnold senior in April 1772 for the Royal Observatory, Greenwich.

  • The Early History of Chronometers : a Background Study Related to the Voyages of Cook, Bligh, and Vancouver
    The Early History of Chronometers : A Background Study Related to the Voyages of Cook, Bligh, and Vancouver SAMUEL L. MAGE Y The purpose of this paper is to outline the historical developments relat­ ing to the chronometer, which played so crucial a part in the voyages of discovery made by Cook, Bligh and Vancouver. The inventor of the first successful chronometer — a technological marvel of precision watchmak­ ing — was John Harrison. His most famous model was the prize-winning H4 of 1759. Kendall's copy of this, known as Ki, helped Cook to plot the first charts of New Zealand and Australia. Ki was also used by Van­ couver, while K2 was once carried by Bligh on the Bounty.1 It is generally well known that in 1714 the British Admiralty offered a prize of twenty thousand pounds (possibly a million dollars in modern terms) for a method that could determine longitude on board a ship to within half a degree (or approximately thirty miles) on a passage to the West Indies. It is, however, less well appreciated how important a part the need for deter­ mining longitude had already played in the process of developing accurate clocks and watches for use on land as well as on the sea. Commander Waters has pointed out that "By about 1254 the Medi­ terranean seaman" knew his "direction between places to within less than 30 of arc", as well as his distances; "By about 1275 ... he had also a remarkably accurate sea chart of the whole of the Mediterranean and Black Sea coastlines", together with the sea compass and relevant table.2 Though there are claims that the sea compass was a European inven­ tion of slightly earlier date, Price feels that the use of the loadstone in navigation was probably of Chinese origin.

Chronometers made by John Arnold and his son John Roger Arnold were valued very highly and usually in use for decades. The watch at hand is an excellent example of this; the movement was fitted into a new, tailor-made case made by Frederick Thoms, who was most likely the most famous casemaker in his time. On the same occasion, the movement was updated with a new dial and a new set of hands.

  • Hornet History Collection 'James Cook'
    Instrument Collection DBG A watch with two heartbeats With a timepiece that references to John Arnold and his son’s watchmaking heritage, Arnold & Son unveils the DBG. The initials stand for the watch’s two major complications, “double balance” and “GMT”. It features the newly developed manufacture A&S1209 calibre. Conceived, designed and manufactured in-house, this superbly engineered wristwatch heralds in the Instrument Collection that combines instrument precision with classical styling. A masterpiece of perfect symmetry, the Instrument DBG Equation GMT features two separate time displays, each driven by its own barrel and gear train with its own escapement and balance. This highly unusual technical specification permits the two displays to be set independently of each other. Although it is a standard feature of watches displaying two or more time zones for the hour hands to be set to different times, being able to set the minute hand as well opens up other possibilities. It means, for instance, that the display can be set to show the precise time in zones that differ from Greenwich Mean Time by a fraction of an hour, such as a quarter or a half. In addition, a subdial at 12 o’clock shows the equation of the two time zones on a 24-hour basis. This enables the wearer to see the time difference between the two zones and also to ascertain whether it is day or night in the second zone. Both time zones share a common permanent seconds in the shape of the long slender hand emanating from the centre of the dial, which is a hallmark feature of the new Arnold & Son’s Instrument collection.

  • The World's Greatest Living Watchmaker, George Daniels, Is
    THE WATCHMAKERS The world’s greatest living watchmaker, George Daniels, is renowned for making every single part of his watches – right down to the spring and screw – by hand. And now another master watchmaker is following in his footsteps… Fe at u r e Jo Durden-Smith P h o t o g r ap h y Christopher Furlong passion l T i m e p i e c e s When in the late 1980s George Daniels visited the Manchester ‘He took me out to the workshop at the back of his house,’ School of Horology in the north of England, the buzz soon went remembers Roger Smith, ‘and looked at it. And then he said: round. He was the world’s greatest living watchmaker, the “W ell, you got it to work – that’s good. But it looks hand-made.
