Watches at the dawn of the machine age, the 20th century, were extremely vulnerable, not just to water but even to dust. They needed to be worn on the wrist. A watch case that could block out dust and moisture. A mechanism that could withstand vibration and was unaffected by position. With the ability to create watch cases and mechanisms suitable for wearing delicate machinery on the wrist, the range of activities for wristwatches expanded dramatically. Almost a century has passed since then. Over the course of 100 years, wristwatches, which once took on unusual forms, can now go directly from a town watch shop's display case to the deep sea. If asked to fly, they can fly to the moon, or even into space. *This book compiles a series serialized in "Design ga Wakaru" (published by World Photo Press), and also includes "Design that Constructs Visibility," which dissects wristwatch design.* Product Information Publisher: World Photo Press (February 25, 2013) Release Date: February 25, 2013 Language: Japanese Mook: 175 pages ISBN-10: 4846529770 ISBN-13: 978-4846529772
