HOROLOGY The Science of Time Measurement and the Construction of Clocks,Watches,and Chronometers

A lovely " Collectors Copy" of the 1937 printing in a scarce but rather crudely restored dustwrapper. A seminal masterwork written by a distinguished Fellow of the British Horological Institute. First published in 1928 this legendary text is a cornerstone of classical watchmaking, precision engineering, and mechanical clock restoration. A dense, unapologetically technical blueprint for calculating and constructing high-grade mechanical timekeepers. Haswell masterfully balances mathematics with workshop practicalities.Topics include Astronomical time measurement and the core physics of tracking seconds: Exhaustive blueprints on pendulum designs, gravity escapements, and train wheel calculations.Watch Engineering: Technical breakdowns of balance wheels, mainspring power delivery, and micro-gear trains.Marine Chronometers: Precision tech dedicated to seafaring navigation and temperature-compensated balances.Detailed Plates and intricate fold-out technical drawings and diagrams visualizing exact component layouts. the "Supplement" in this edition refers to a highly technical update appended to the back of the book written by Haswell to bridge the gap between classical 1920s mechanical horology and the major technical breakthroughs of the 1930s.
