One of George Daniels's central contributions to horology is his co-axial escapement. Having observed that the dominant lever escapement begins to change its rate after a year or two -- a disturbance caused by the sliding action of the impulse elements of the escapement -- Daniels set about developing a mechanism that avoided this problem. The result of his efforts was the co-axial escapement, a mechanism in which he sought to combine the strengths and eliminate the deficiencies of existing watch escapements, the lever escapement foremost among them. First devised in 1977, today it remains largely the same as fitted in watches of Daniels's own manufacture, as well as those of several wrist-watch manufacturers. This book explains the action of the escapement in terms accessible to both expert and layman, and is accompanied by a series of detailed line drawings.

"The Mechanics of Mechanical Watches and Clocks" presents historical views and mathematical models of mechanical watches and clocks. Although now over six hundred years old, mechanical watches and clocks are still popular luxury items that fascinate many people around the world. However few have examined the theory of how they work as presented in this book. The illustrations and computer animations are unique and have never been published before.
It will be of significant interest to researchers in mechanical engineering, watchmakers and clockmakers, as well as people who have an engineering background and are interested in mechanical watches and clocks. It will also inspire people in other fields of science and technology, such as mechanical engineering and electronics engineering, to advance their designs.

For Neophytes - to learn the fundamentals, and appreciate the main features of a model, its qualities and weaknesses. For amateurs - to create the desire to know more about fine watches. For connoisseurs - to revise important concepts and even increase their knowledge. This new edition includes new illustrations. What is a beautiful watch? How do you make a good choice? The Magic of Watches explains how and why these little objects are so precious, fascinating and exciting. The book presents paradoxes: why a one-million-dollar watch might be less precise and more fragile than one that costs 15 dollars. It comes back to the origins of the measurement of time: how did we go from the water clock to the wristwatch? The book goes on to technique: how does a mechanical movement work? How does a quartz one work?; delves into details: what is a 'complication' and when do we speak about 'chronometer'?; showcases art: how do we enamel a dial? The Magic of Watches is unique: it focuses in detail on the basics in order to understand and love watches better.

Timekeeping is an essential activity in the modern world, and we take it for granted that our lives our shaped by the hours of the day. Yet what seems so ordinary today is actually the extraordinary outcome of centuries of technical innovation and circulation of ideas about time.
Shaping the Day is a pathbreaking study of the practice of timekeeping in England and Wales between 1300 and 1800. Drawing on many unique historical sources, ranging from personal diaries to housekeeping manuals, Paul Glennie and Nigel Thrift illustrate how a particular kind of common sense about time came into being, and how it developed during this period.
Many remarkable figures make their appearance, ranging from the well-known, such as Edmund Halley, Samuel Pepys, and John Harrison, who solved the problem of longitude, to less familiar characters, including sailors, gamblers, and burglars.
Overturning many common perceptions of the past-for example, that clock time and the industrial revolution were intimately related-this unique historical study will engage all readers interested in how "telling the time" has come to dominate our way of life.

All in Good Time is the remarkable story of George Daniels (1926-2011), the master craftsman, who was born into poverty but raised himself to become the greatest watchmaker of the twentieth century. Daniels stands alone in modern times as the inventor of the revolutionary co-axial escapement, the first substantial advance in portable mechanical timekeeping over the lever escapement, which has dominated ever since its invention in 1759. Daniels's love of mechanics embraced not only the minute, however - he was also a passionate collector and driver of historic motorcars. This revised and expanded edition of his autobiography also contains a new section that illustrates and discusses over thirty of the pocket and wrist-watches Daniels himself made over the years. Witness here the triumph of intelligence, ingenuity, matchless skill and singularity of purpose over the most unpromising of beginnings.

Time is a great mystery. A changeable element, which expands or vanishes, but that appears concrete as it is marked by the passing of seconds, minutes, hours, days, and years. The path toward the capture of minutes and seconds coincided with the phases of scientific evolution that allowed man to manufacture watches that are increasingly reliable, but that are also in tune with changes in customs, social needs, and aesthetic canons. This book covers the art of watch manufactory as well as 60 great models, covering both their technical evolution and style trends. In each chapter in-depth studies will guide the reader to the history of the most important manufacturers, the personalities linked to the models treated, technical innovations, styles of the period, or records achieved by the wristwatches: from the watch that helped Charles Lindbergh during the first transatlantic solo flight, to the one worn by Sir Edmund Hillary on the top of Mount Everest, the most iconic models will be discussed in detail.

Dealing with a complicated watch used to be a rare job for the watch repairer, but with the popularity of the automatic, it is almost commonplace. Furthermore, the increased interest in calendar work, alarm watches, and chronographs will undoubtedly bring more and more complicated work into the workshop. This book deals with complicated work essentially from the repairer's point of view. The action of each mechanism is briefly and clearly described because understanding this is essential to proper servicing, repair and testing for functioning. Dismantling and assembly instructions are given, as well as oiling charts and - most important - hints on fault-finding and their rectification. Another essential feature of the book is that it deals with all complicated work - from the relatively simple automatic to the triple-complicated watch with chronograph, calendar and repeater work, and the very complicated clock watch. Exceptional care has been taken in the preparation of diagrams, which have been drawn from actual movements in various stages of assembly, so that the reader can actually work with the book illustrations beside the watch itself. As always with books by Donald de Carle, instructions are easy to follow and there is no reason why anyone well versed in ordinary work and able to use watchmakers' tools should not become a specialist in complicated watches and their repair.

Margaret Gatty (1809 1873) was an English writer best known for her researches on sundials and British seaweeds. After marrying the Rev. Alfred Gatty in 1839, she moved to Ecclesfield, Yorkshire, where she pursued her literary and scientific studies. This volume, first published in 1872, contains detailed descriptions of various styles of sundials, many taken from Gatty's own collection. Over 350 sundials from across Britain and Europe are described, and each sundial's location is noted in this work, which was one of the first popular books on the subject. Examples included range from portable sundials to early Saxon sundials, as well as the more familiar church sundials. This volume is one of Gatty's best known works, and remains a valuable reference for the various types of sundials and the variations and similarities in their mottoes.

This book is a practical guide to selecting, setting up and using an engineer's lathe to create parts specifically for clockmaking or clock repairs. It begins as an instructional manual and consequently the first chapter assumes that the reader does not yet have a lathe and needs advice on choosing one. With over 160 diagrams and photographs, topics include: choosing and setting up the lathe; turning - materials and facing; boring and milling techniques; chucks, collets and face-plates; creating a height-centring gauge; pivots, wheels and pinions; removing and mounting gear wheels; fly cutters; making a flat depthing tool and, finally, creating centre marking tools. The intent is to provide a gentle learning curve for the practical use of the lathe.

There are names in horological history that echo much more than just watches... Such is the case of Jaquet-Droz, 18th Swiss watchmakers with an international horizon, whose ceremonial clocks, prodigious androids, fashionable birdcages, pocket watches with moving scenes or collector's snuffboxes remain the stuff of dreams for passionate enthusiasts. Today, the Maison Jaquet Droz continues to draw its inspiration from this rich heritage in order to reinterpret techniques and aesthetics, pushing back the boundaries of watchmaking and representing a perpetual source of fascination for collectors. Based on the latest research on the subject and published on the occasion of the 300th anniversary of the birth of Pierre Jaquet-Droz (1721-2021), this book offers a deep dive into the history of characters with a captivating journey. Born in La Chaux-de-Fonds, in what was then the principality of Neuchatel, Pierre Jaquet-Droz founded a watchmaking workshop and developed it through a combination of technical, artistic and commercial skills enabling it to reach international markets. His son Henry-Louis developed the family business and further diversified production, a significant portion of which found its way to China and its dignitaries, devotees of luxurious and ingenious mechanical marvels. This richly illustrated book aims to enable a rediscovery of their mechanical masterpieces as well as those of the Maison Jaquet Droz, whose rebirth and recent history are recounted here. These splendid historical and contemporary pieces embody a love of technical challenges and a taste for artistic refinement, adhering as much as possible to the sources of inspiration offered by nature. The Worlds of Jaquet Droz thus reveals part of the expansive universe of pre-industrial watchmaking while drawing parallels between past and present productions.

This book is a scholarly study of a virtually unknown aspect of the history of horology (timekeeping), compiled from Chinese and Japanese historical and literary records, some of which are translated and published here for the first time. Incense timekeepers played an important role in early Chinese social and technological history, in addition to their use for time measurement. They were used in temples for religious rites, in agricultural regions for regulating water for irrigation, in palaces and government offices, and in the studies of scholars. A fascinating compendium of knowledge about a neglected aspect of Oriental culture, this book will appeal not only to historians of China and Japan, but to the growing number of collectors and museum curators who are interested in incense clocks. It is illustrated with black and white halftones of a large number of the clocks, which are renowned for their beauty of design and quality of workmanship. The book also includes a catalogue of incense clocks which have appeared in auction houses and museums.

The pendulum: a case study in physics is a unique book in several ways. Firstly, it is a comprehensive quantitative study of one physical system, the pendulum, from the viewpoint of elementary and more advanced classical physics, modern chaotic dynamics, and quantum mechanics. In addition, coupled pendulums and pendulum analogs of superconducting devices are also discussed. Secondly, this book treats the physics of the pendulum within a historical and cultural context, showing, for example, that the pendulum has been intimately connected with studies of the earth's density, the earth's motion, and timekeeping. While primarily a physics book, the work provides significant added interest through the use of relevant cultural and historical vignettes. This approach offers an alternative to the usual modern physics courses. The text is amply illustrated and augmented by exercises at the end of each chapter.

The history of Rolex is inextricably linked to its founder Hans Wilsdorf, who took the first steps in the world of Swiss watchmaking as he dreamed about a timepiece that could be worn around the wrist. This experimental research led Rolex to achieve its highest goals in both technological innovation and in the use of the finest materials alone. Its models have been photographed on the wrists of political leaders, sports champions, and film and fashion celebrities, transforming each Rolex into a fully-fledged status symbol, a synonym of elegance and precision. Including essays with a historical and technical slant, in-depth descriptions of the most representative pieces and a brief glossary, the pages in this book sparkle with golden hands, diamond-studded dials and patent-leather watchbands, illustrated in period photographs and macro-detail. The volume ends with a chapter dedicated to the most amazing auctions that saw the sale of the Geneva-based company's vintage watches. (Reprinting 10.02.2020)
