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.

Time is considered as an independent entity which cannot be reduced to the concept of matter, space or field. The point of discussion is the "time flow" conception of N A Kozyrev (1908-1983), an outstanding Russian astronomer and natural scientist. In addition to a review of the experimental studies of "the active properties of time", by both Kozyrev and modern scientists, the reader will find different interpretations of Kozyrev's views and some developments of his ideas in the fields of geophysics, astrophysics, general relativity and theoretical mechanics.

"The longcase clock has been a part of the Englishman's home for some 300 years and has gained a place in his heart seldom if every achieved by any other domestic item. An example of its importance in family life is that it, with the bed and the house, was nearly always mentioned specifically in the will." In Derek Roberts's important new book, readers find a wealth of valuable information detailing the British origins, evolution, and wide range of longcase clocks that have been produced since the sixteenth century. In twenty chapters Mr. Roberts provides a detailed overview of many facets of these beautiful and useful art works, including early square dial, rare, astronomical and equation clocks, walnut breakarch longcase clocks (and those in other woods), and thirty-hour clocks. Other chapters detail various dial and decoration forms, precision timekeeping, important makers, and clocks of the Victorian and Edwardian eras right up to modern times. A glossary of terms and lengthy index of makers are included. In British Longcase Clocks, Mr. Roberts share his wealth of knowledge enthusiastically and presents over 300 black and white and full-color photographs of details and whole clocks. His book will interest clock owners and all who love fine furniture.

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.

This profusely illustrated volume forms a step-by-step instruction manual on the repair of mechanical clocks and watches. Donald de Carle was a Fellow of the British Horological Institute, and the author of many standard works on the subject of horology, who based his writings on many years of practical experience. The book begins with simple clocks and watches then proceeds to more complicated types. The tools and apparatus needed are described and illustrated. Modern types of mechanical clock are mainly dealt with, but attention is also given to the movements of older long case and fusee types as many of them are now being repaired as a result of interest in antique clocks. The chapters on watch repairing deal with chronographs and repeaters as well as self-winding mechanisms. The latest developments in ultrasonic cleaning of horological movements and their electronic timing are also described and illustrated. This work is an invaluable guide for all concerned with the repair not only of clocks and watches but also of small mechanisms in general.

Do you know that black holes can affect time? that Stonehenge is a giant calendar? that the Oracle Bones of the North China Plain predict the phases of the moon? that the Pyramids are giant compasses? how Jonathan Swift knew that Mars had two moons when he wrote Gulliver's Travels? that the effects of black holes are described in the story of Alice in Wonderland? that an atomic reactor existed 2 billion years ago in Equatorial Africa? that an electron on the other side of the galaxy can deflect a billiard ball? that Schr dingers cat is both alive and dead? Derek York fathoms these and many other mysteries of time and space in In Search of Lost Time. A reflection of York's obsession with time and its measurement, the book discusses the mind-bending universe of the special and general theories of relativity, the ghostly world of quantum mechanics, and the unpredictable haunts of chaos. It explores the pyramids of Egypt, Stonehenge, and the South China plain; the universities of Cambridge, McGill, and Chicago; the Patent Office in Berne; and back to the Ethiopian desert on the banks of the Awash River. Companions to share and illuminate the path range from Jonathan Swift's Gulliver's Travels and Lewis Carroll's Alice in Wonderland to J.B. Priestley's Dangerous Corner. It also presents the father of master-spy Kim Philby in the Empty Quarter of Arabia, the fantasist Velikovsky in the clouds, and Newton, Darwin, Rutherford, Einstein and the great Earth scientists of this century who fathomed the depths of lost time and discovered the age of the Earth. Written in an engaging, nontechnical style, this book will delight and amaze all who encounter it.

A lavishly illustrated history of Movado from its roots in the Jura Mountains in 1881 through more than a century of tradition and technological advancement. Over the years, Movado earned a reputation for pioneering the art of wristwatches, high-precision movements, and watches with complications, as well as water-resistant watches, and their accomplishments are celebrated here in 250 color photos and informative text.

A long-awaited reprint of an important illustrated reference work on the general history of the watch from 1500 to 1980. When Watches was first published in 1965 it quickly gained for itself a reputation as the foremost general history of the subject and, following the expanded edition in 1979 which covered recent years past 1830, this has remained unchallenged in horological history. In this long-awaited reprinted edition, collectors and horological students can again make use of the reference illustrations and history in this work as approached by the leading horology historians and clockmakers of the twentieth century. Clutton and Daniels write expertly on the vast history of watches, through the changing tastes and styles of collectors and makers, as well as imparting their own knowledge on various technical aspects within the watches. The expansive historical section encompasses both decorative and mechanical aspects of mid-sixteenth to late twentieth century watches, including those by George Daniels himself, detailing the rich history behind more modern designs and fascinations. These later years include a variety of semi-experimental escapements, as well as covering the development of the precision watch and work leading to it by Ferdinand Berthoud and Pierre Le Roy, discussed alongside John Arnold in England, to satisfy the technical-minded collector. Horology and collecting have grown with the changing technologies, and watches continue to be produced to an exceptional technological standard. Precision watches from the 1730-1930 period are covered in detail, as well as high standard Swiss and American watches of the last hundred years; these highly complicated watches benefit greatly from having both colour and mono illustrations to clarify the details. For a truly comprehensive understanding of escapements, photographs of these have been included alongside a critical approach to this essential mechanism. Since its first publication, Watches has provided an essential work of reference and history behind some of the most renowned minds and creations. Now reprinted for a new generation of collectors and students, and featuring over 600 illustrations, the technical and decorative elements of historical watches can be studied and enjoyed once more.

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.

This book's contents include: general condition of the movement; cleaning and oiling; balance pivots; fitting a flat balance spring; fitting a breguet balance spring; positional timing; further considerations when fitting a spring and observing the point of attachment; general notes on springing and timing; other methods of positional adjustment; and, timing machines. "No writer can have added more volumes to the horological bookshelf than Donald de Carle, and his careful and detailed approach to the technical side of the craft has done a great deal to improve the standard of knowledge of a host of craftsmen, and has gained him readers in every part of the world. The many craftsmen who are already familiar with Mr de Carle's earlier work, Practical Watch Repairing, will note a great similarity in the attitude of mind behind both books, and, indeed, this latest volume is, to some extent, a companion and a follow-on from the previous book, for it carries the reader into what is, undoubtedly, the most exacting and skillful aspect of all work on watches." Horological Review

Many clock repairers carry out excellent work but avoid cutting their own wheels and pinions, fearing it is too complicated and involved. This book, written by an experienced clock and tool maker, dispels those fears and gives a step-by-step guide to an extremely satisfying aspect of horology. This book is written for both the amateur and professional involved in the making and restoring of clocks, and for anyone who intends to start building up a workshop and requires a guide to the equipment and how to use it.

Navitimer. A mysterious name at first glance. It is in fact a contraction of two words, which correspond to the two major functions of a revolutionary watch: NAVIgation and TIMER. A chronograph designed for airborne navigation. But much more than that, an exceptional destiny, shaped by extraordinary and visionary actors. From the very beginning of its existence, in 1884, Breitling specialised in time measurement, namely the design of timers and chronographs. It was in the 1930s that the foundations of a close relationship with the world of aviation and aeronautics were laid, under the aegis of Willy Breitling. These ties have remained unbroken ever since. In 1952, in collaboration with the AOPA, the largest aeronautical association of the time, Breitling launched the development of the Navitimer, which offered what no other watch manufacturer had ever proposed: a chronograph combined with a slide rule for aircraft pilots. The Navitimer was available only to AOPA members in 1954, and then marketed to the general public in 1955. For 70 years now, the Navitimer has enjoyed glory, flown into space and weathered crises, integrating numerous evolutions without ever losing its original DNA. It has appealed to several generations of professionals, celebrities and lovers of exceptional watches, undoubtedly earning its status as an icon of watchmaking history. This second book in the Watch Stories series, dedicated to the history of emblematic timepieces, traces its heroic and unique destiny from its creation to the current models.

Paul Newman wore his Daytona Rolex every single day for 35 years until his death in 2008. The iconic timepiece, probably the single most sought-after watch in the world, is now in the possession of his daughter Clea, who wears it every day in his memory. Franklin Roosevelt wore an elegant gold Tiffany watch, gifted to him by a friend on his birthday, to the famous Yalta Conference where he shook the hands of Joseph Stalin and Winston Churchill. JFK's Omega worn to his presidential inauguration, Ralph Lauren's watch purchased from Andy Warhol's personal collection, Sir Edmund Hillary's Rolex worn during the first-ever summit of Mt. Everest...these and many more compose the stories of the world's most coveted watches captured in A Man and His Watch. Matthew Hranek, a watch collector and NYC men's style fixture, has travelled the world conducting firsthand interviews and diving into exclusive collections to gather the never-before- told stories of 76 watches, complete with stunning original photography of every single piece.

This book is long overdue documentation on automatic wristwatches from countries other than Switzerland. These watches were always considered superior micro-mechanical products and posed a challenge to technicians. It was only a question of time, before the collectors' interest in these watches expanded from Swiss watches to those of other origins. A total of 123 watches are illustrated in three different views and are described in detail.

For all those who are interested in horology, whether as a hobby or within the trade, this user-friendly guide is invaluable as a wealth of information for the internal workings of clocks. Eric Smith provides a fully comprehensive manual to the repair of clocks, whether modern or antique. Lucid language accompanies practical diagrams and photographs to bring clarity to what is often a highly complex task. The author recognises the curiosity which many feel about the workings of clocks. It is for this reason that the author has written a guide which does not depict horology as too complex for those outside the trade, but rather as a fascinating and accessible occupation. The ten chapters go through the practical stages of how different clocks work and the tools and materials needed. Pendulum clocks, 30-hour, 8-day and 400-day clocks, chiming, striking, and electric and alarm clocks are all covered in detail. This new revised edition includes a chapter on working with more advanced tools including the lathe. The first chapter addresses the tools and materials which are required for repair, whilst the second chapter provides an explanation of the principles of clock mechanisms. The author subsequently takes the reader through specific aspects of clocks in each chapter, from the pendulums and balance wheels to cases and hands. A chapter on electric clocks gives advice on a significant sector of the clock market. In addition, this volume includes a glossary of terms, a bibliography and a list of suppliers of materials. It is also fully indexed. The author recognises that there is much in horology which cannot be self-taught from a book, yet Clocks and Clock Repairing is both a book to stimulate interest and a handy reference guide.

Of all the forms advertising has taken through the years, few have been as effective as those found on the dials of America's clocks. People want to know what time it is, and advertisers found creative ways to give them the time and "a message from their sponsors." The results are sought after by collectors around the world. For the first time, Mike Bruner has gathered together many of these examples of advertising ingenuity in one beautiful volume. From the wooden mechanical examples of the 1870s to the later neon electric models, the advertising clock is celebrated. In all over three hundred examples are illustrated with full color photographs. A price guide is included.

The phenomena of Japan emerging as one of the most competitive industrial nations in the twentieth century and the general shift of competitiveness to East Asia since the 1980s have been widely studied by many scholars from different fields of the social sciences. Drawing on sources from Japanese, Swiss, and American archives, the historical analysis of this book tackles a wide range of actors and sheds light on the various processes that enabled Japanese watch companies to transfer technology and expand commercially starting in the second half of the nineteenth century. By exploring the case of the watch industry, this book serves to establish a better understanding of the origins of the competitiveness of Japanese manufacturing and its evolution until its decline in the post-bubble economy (in the 1990s and 2000s).

This range of clocks used to be considered the common, household clock which many people recognized but for which little documentation was available. Rick Ortenburger now presents the book that will fill this void. Vienna regulator clocks were first produced in Vienna, Austria about 1780 and then became a familiar style made also elsewhere in the German-speaking world. Included are early, transitional, serpentine, altdeutsch, Baroque, and factory-made types from 1780 until about 1930, of one, two, and three-weight movements. The author has done his own research in Europe and America in both German and English so he is able to present much original information in a pleasing format for the average reader. His brief, factual text, supported by good photographs, useful in identifying the period of manufacture, may be the book's most useful feature to the serious collector. Her fully explains the production of Gustav Becker, Junghaus, HAC, Lenzkirch and competitive factories whose products are still on the market and well within the financial means of the vast majority of clock enthusiasts. He also covers many rare and exotic regulators such as long-duration clocks and variations from the norm.

"Mechanical and Quartz Watch Repair" is targeted primarily at those who want to learn about watch repair, and features movements that are representative of those found in other watches. The easy to follow instructions are appropriate to both professional repairers and enthusiasts. Material covered includes the working environment, overhauling basic mechanical watches, automatics, stop watches, chronographs, some restoration, and basic quartz watches--both analog and liquid crystal display.

This practical, informative and beautifully illustrated book will be essential reading for all those with a passion for mechanical clocks. It will be of particular interest to both amateurs and professionals alike who wish to work on clock cases and restore them in the correct way according to modern best practice. The authors, both experienced horological restorers, examine in detail the restoration processes and provide detailed descriptions, and a wealth of photographs and diagrams. Difficult, and often misunderstood, areas of restoration and conservation are explained in the context of twenty-first thinking. The haphazard approach to clock case restoration, which has continued in some quarters almost to the present day, is no longer considered appropriate for preservation of the rapidly dwindling stock of clocks that represent our horological heritage. Accordingly, the authors emphasize that sensitive and sympathetic clock case restoration is essential and, indeed, is the most economically attractive approach to adopt.

How can you tell a fake watch from a real one? Where are fakes made? What grades of quality can one find among so-called "replicas"? How can one buy a watch on the internet? How can one avoid fraudulent copies? These are just some of the questions to which any wristwatch enthusiast needs to find answers in an era when counterfeiting luxury products has become an industry in its own right. This book, of which the greater part is devoted to the most prestigious watch brands, provides readers with vital information on identifying fakes. It aims to ensure that buying a watch from a private individual, from a professional or on the internet (the global hub for the sale of fake watches) does not turn out to be a nightmare! Illustrated with over 500 photos, the differences between original and counterfeit models are exposed in detail (mechanisms, dials, bracelets, etc.). To our knowledge, no other work of this type has been published to date, doubtless due to the explosive nature of this fascinating topic.
