The first and most comprehensive step-by-step guide on the subject, Watchmaking has become a classic in its own right. This new edition is updated to include a new section which discusses and illustrates a variety of the author's own watches. The author's principal aim in writing this book has been to inspire and encourage the art of watchmaking, especially among a new generation of enthusiasts. The making of the precision timekeeper is described, step by step, and is illustrated at each stage with line drawings and brief explanatory captions. Great care has been taken to ensure the text is easy to follow and to avoid complicated technical descriptions.

Here is a unique book. It describes the theories and processes of repairing and adjusting the modern watch in precise and meticulous detail: a thing which has never been done so completely before in the many books on the same subject. As a text book it is a revelation. Taking nothing for granted, except the ability to read and comprehend a simple description of mechanical processes, de Carle takes his reader through every stage and every operation of watch repairing ...and to deal with them thoroughly is quite a programme - it takes 300 pages containing 24 chapters, two appendices and 553 illustrations. The fine draughtsmanship and accurate technical detail of the illustrations set a new standard. Practical Watch Repairing can justifiably claim to be the best illustrated book on practical horology yet issued, and one of the best of its kind on any subject. The publication of the book marks the beginning of a new epoch in the study of the mechanics of horology.

According to Roger Caillois, play is an occasion of pure waste. In spite of this - or because of it - play constitutes an essential element of human social and spiritual development. In this study, the author defines play as a free and voluntary activity that occurs in a pure space, isolated and protected from the rest of life.

Weapons of myth and scandal, that is the best way to describe the spigot weapons deployed by the British in the Second World War. Unlike conventional mortars, a spigot mortar does not have a barrel through with the round is fired. Instead, the general concept involves a steel rod – the ‘spigot’ – onto which the bomb is placed before it is fired. This design was, as David Lister reveals, the basis of a number of successful weapons used during the Second World War. The myth of the PIAT man-portable anti-tank weapon is, for example, tied closely to British paratroopers struggling in the ruins of Arnhem with an inadequate design, one inferior to the German equivalent. Similarly, the myth of the Blacker Bombard is of a useless weapon, one of dubious quality, that was dumped on the unsuspecting Home Guard. In reality, neither scenario is the case. Both weapons were devastating creations of war, often superior to any other nation’s counterpart. At sea, the Hedgehog anti-submarine weapon was another powerful spigot weapon. It was undoubtedly capable of sweeping the U-boats from the sea and even winning the Battle of the Atlantic before it had really begun. That it did not is one of the great scandals of the Second World War, one hidden by wartime secrecy until now. In Defeating the Panzer-Stuka Menace the author explores a large number of spigot weapons from the Second World War, many of which were created by the fertile mind of one of Britain’s great weapon inventors, Latham Valentine Stewart Blacker.
