About the Author

Gisbert L. Brunner, born in 1947, has been working with precision time-keeping instruments since the 1960s, primarily wristwatches. During the quartz watch crisis in the 1970s, he discovered a new love for the seemingly moribund mechanical timepiece as well. His passion for collecting chronographs led him to publish his first magazine articles on the subject in the early 1980s. Brunner has since written more than 15 books about the field and is in demand worldwide as a public speaker.
