ORIGINAL HISTORICAL DOCUMENT
This document from the 2000s was used to sell this DuBois et fils Chronograph.
A tribute to the first wrist chronograph
The development of a new timepiece was on the agenda for DuBois et fils in the 1920s. The company's head at the time, Jules DuBois, had a clear vision:
'This watch should not only be worn at the racecourse or while driving, but also in the evening.'
At that time, the pocket watch was still a natural accompaniment to evening wear. However, DuBois et fils showed foresight, contributing to the dawn of a new era. The wristwatch was no longer solely used for functional purposes during the day; it also found its place in elegant social settings.
The chronograph evolved from a sports instrument into a stylish timepiece.
Today, we are auctioning this timepiece from the 2000s, which was inspired by the early days of the wrist chronograph in the 1920s.
