Features: A sundial that determines time based on the position of sunlight, and an hourglass that records time using the flow of sand. They are also called "solar clocks" and "sand clocks." Since celestial movements are based on time, and mechanical structures must have devices to form time intervals to achieve timekeeping, early "escapements" emerged. Thus, the "Water Transport Automata" became the ancestor of clocks. "Chinese Market Watches" have become a very unique collecting category internationally. "Authentic, Exquisite, and New" are the three principles of antique watch collecting. This book poses thirty questions in sequence, providing a detailed introduction to what the ancestor of clocks is, when it appeared, how mechanical clocks developed, what "Chinese Market Watches" are, what reference books are available for collecting watches, what are "dream watches," what are their characteristics, which classic watch models are worth collecting, what are multifunctional watches, what are tourbillons, what are the metal engravings on watch casings, what do they represent, and how to maintain antique watches, all with illustrations and descriptions!
