1950s Chronographs

The Tag Heuer company has its roots in 1860 when Edouard Heuer founded a watchmaking company in St-Imier, Switzerland, patenting his first chronograph in 1882. In 1887 Heuer patented an "oscillating pinion" still used by major watchmakers for mechanical chronographs.

On September 13, 1999, TAG Heuer accepted a bid from LVMH Moët Hennessy Louis Vuitton S.A. of 1.15 billion francs ($739 million) contingent upon a transfer of 50.1% of stocks.[8]

In 2008 TAG Heuer partnered with CHRONELEC, a European leader in the transponder timing, to push timing technology to a new extreme of precision of sports timing as to bring complete timing designs to tracks and stadiums for most prestigious sports.
