 According to factory records, the last movement to be used in an American LeCoultre watch was shipped out of Le Sentier in 1976.Some collectors and misinformed dealers have made the erroneous claim that American LeCoultre is not associated with Jaeger-LeCoultre Switzerland.The confusion stems from the 1950s, when the North American distributor of LeCoultre watches was the Longines-Wittnauer Group, which was also responsible for the distribution of Vacheron Constantin timepieces.
