Book excerpt: "Initially designed for automobile racing teams and engineers, the OMEGA Speedmaster embarked on a very different trajectory when NASA chose it to accompany astronauts heading for the Moon in 1965. Its involvement in the space adventure has propelled the Moonwatch to the top of the list of celebrated timepieces. After years of research and observation, the authors present a complete panorama of the Moonwatch in a systematic work that is both technical and attractive, making it the inescapable reference book for this legendary watch. This third edition has been enriched with 17 new models, revised information and a new chapter featuring pictures of astronauts and their Speedmasters."--Back cover.
