The difference between the Cartier Tank and the Tank Louis. Louis-Fran?ois Carti

The difference between the Cartier Tank and the Tank Louis. Louis-Fran?ois Cartier founded his eponymous brand in Paris, France, in 1847. In 1917, during World War I, the Tank model was introduced. Its rectangular design was inspired by the shape of French tanks used in the war. By the end of 1919, six Tank models had been commercialized, marking the start of full production. This watch's aesthetic was a stark departure from the popular round-cased pocket watches of the time.
