Coming from the first private owner, the present watch has never been at auction. All the pictures represent the best provenance for a vintage collectible timepiece. These images taken in 1975, 1987, 1991 and 1992 are an amazing proof that the current owner used the watch through the years. Purchased by his father in 1968, it was left as a gift to his son for his eighteenth birthday who has used it regularly until today. Considering the age and the daily use, the watch is in beautiful conditions.
