master watchmaker at Vacheron Constantin as well as the one in charge of regulating the movements submitted to the observatory trials.
In 1949 he obtained a record at the Geneva Observatory trial for the adjusting of isolated pieces with 922 points out of 1000.
He worked for VC as far as I know from the 1920s-1950s.
Thanks for Alex.
I have asked you a difficult question. I'm sorry.
Because I thought that his achievement was big as for the birth of the chronometer royal, I post.
Royal which was launched in 1907 more than a decade before he joined the company. He of course was part of the prestegious awards won at the observatory trials as he adjusted the watches submitted by VC.
