European Watch Clock and Jewellery Fair 1986 BF 211
Designed by master watchmakers working with the aid of computers, this wristwatch with a minute repeater has required two and a half years of patient research. The 9-line movement comprises more than 750 parts. Yet it is a mere 3.2 ’rim thick. It strikes hours, quarters and minutes. Case in 18K gold. (BLANCPAIN)
