I took this watch with me on a visit to the Victoria and Albert Museum in London as I had a letter of introduction to Jonathan Betts; the curator of Horology there. After showing him the watch, he took Nancy and I down to the student room where they do all the cataloging and restoration of their valuable pieces. He further told us some of the history of Earnshaw and the interesting fact that they had pieces numbered close to my watch, which is #3484.

Testing and Adjusting Clock Movements
SEMCW3-07 Testing and adjusting clock movements Overview This unit identifies the competences you need to carry out tests and adjustments on clock movements, in accordance with approved procedures. You will be required to carry out tests on a range of clock movements, such as longcase, regulator, two and three train fusee, two and three train going barrel, and one and two train with platform escapement, to establish that they are functioning correctly. You will be required to carry out tests and adjustments which will include function, duration, and variation in accuracy during the duration, rate and beat. Your responsibilities will require you to comply with organisational policy and procedures for carrying out the testing and adjustment activities, and to report any problems with these activities that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying appropriate testing and adjusting procedures to clock movements. You will understand the clock movements being tested and adjusted, the test equipment being used, the various testing procedures and their application, in adequate depth to provide a sound basis for carrying out the activities, correcting faults, and ensuring that the clock movement functions correctly. You will also be expected to report where the outcome of the tests and adjustments identifies the need for further investigation or corrective measures. -

Chapter 2 A Brief Review of the Mechanics of Watch and Clock According to literature, the first mechanical clock appeared in the middle of the fourteenth century. For more than 600 years, it had been worked on by many people, including Galileo, Hooke and Huygens. Needless to say, there have been many ingenious inventions that transcend time. Even with the dominance of the quartz watch today, the mechanical watch and clock still fascinates millions of people around the, world and its production continues to grow. It is estimated that the world annual production of the mechanical watch and clock is at least 10 billion USD per year and growing. Therefore, studying the mechanical watch and clock is not only of scientific value but also has an economic incentive. Never- theless, this book is not about the design and manufacturing of the mechanical watch and clock. Instead, it concerns only the mechanics of the mechanical watch and clock. -
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. -

Timekeeping and astronomy were complementary methods for ascertaining longitude; they were carried out using chronometers and by taking lunar observations. The article explains who was responsible for handling the astronomical readings on the expedition; the performance of the chronometers used; Flinders’s comparisons of the longitudinal readings with the work of previous navigators; and the reasons why dissemination of the longitudes taken during the voyage was delayed. The article shows how the combined use of chronometers and lunar observations helped Flinders to achieve scientific accuracy in his charting of coastal Australia in the atlas to his major work entitled A Voyage to Terra Australis. Keywords Australia, longitude, maritime exploration, Matthew Flinders, navigation, scientific instruments During the eighteenth century, important improvements in determining longitude ena- bled navigators to establish clearly their position and time relative to a given meridian. Navigators needed to know precisely their east–west position on the globe in relation to an initial prime meridian (based on Greenwich time in the Anglophone world) in order to sail safely across the oceans.1 Finding latitude at sea presented fewer technical and 1. -

35 Years of the Daniels Co-Axial Escapement Embodied in an Extraordinary Collaboration
35 YEARS OF THE DANIELS CO-AXIAL ESCAPEMENT EMBODIED IN AN EXTRAORDINARY COLLABORATION The response to our initial release was exceptionally positive and we are now pleased to present more details regarding the recently announced collaboration between Dr. George Daniels C.B.E., M.B.E. and Roger Smith for a series of Co-Axial Anniversary wristwatches. As many of you will undoubtedly already know, the Daniels co-axial escapement must be counted as the 20th century’s major innovation in watch escapement development, following on the earlier footsteps of several famed 18th century English horologists including George Graham, Thomas Earnshaw and Thomas Mudge. It is a story unto itself of Dr. Daniels’ efforts to gain recognition for his landmark horological creation within a skeptical industry that took time to understand its inner workings and unique qualities. The key advantage that Daniels’ escapement has over the lever escapement lies in the highly efficient method with which power is delivered from the mainspring to the balance wheel. Simply put, the standard lever escapement achieves this final delivery of power via a long sliding action while the co-axial achieves its delivery of power by a simple pushing action, similar to the motion used to impel a gate or door to swing open. This important difference in the way power is finally delivered means that the co-axial escapement is unaffected by any deterioration in the condition of an applied lubricant, whereas the lever escapement’s proper function is totally reliant upon the quality and type of lubricant used.
