I am selling this vintage Buren Grand Prix Super Slender men's watch with the famous micro-rotor automatic watch moment. The watch was made in the 1960's, the gold plated case measures 34mm. It comes delivered on a new leather strap that fits a 19cm wrist. This watch is well known for the micro rotor movement (cal. 1006), an important innovation to make automatic watches significantly thinner by placing the rotor inside of the movement instead of placing it on top. This principle is still being used by brands like Patek Philippe. The watch has just been serviced by a master watchmaker and is running accurately. It comes delivered in the original box. This watch is offered without a reserve price, please examine the photos before bidding.
