作者介紹 Gisbert L. BrunnerBorn in 1947, Gisbert L. Brunner has been working with precision timepieces of all kinds, especially wristwatches, since the 1960s. During the quartz crisis of the 1970s, his love for the seemingly vanishing mechanical timepieces grew even stronger. His ardent enthusiasm for collecting inspired him to publish his first articles in the early 1980s. Gisbert L. Brunner has published more than 15 books on this subject to date, and he is in demand as a speaker all over the world.
