The Beginning of Jaeger Lecoultre Watches

It was in 1866 that Antoine LeCoultre and his son, Elie, moved operations of watch making under one roof.  Up until that point, most Swiss watchmaking was still done individually in peoples homes.  Moving the process under one roof allowed them to make the most of combining abilities.  They would also start using a steam-engine machine to operate their tools, thus making them more efficient.  This would eventually lead to watches, like the Jaeger-LeCoultre Reverso Squadra Chronograph that we all know today.
