Gisbert L. Brunner, born in 1947, has been involved with precision timepieces of all kinds since the 1960s, primarily wristwatches. During the quartz watch crisis in the 1970s, his love for the seemingly dying mechanical timepieces increased even more. His passion for collecting led to his first articles in the early 1980s. In the meantime, Brunner has published more than 25 books on the subject. He is in demand worldwide as a lecturer.
