The Tank Basculante is one of the most iconic designs from Cartier. it was originally created in the 1930's for polo players.The model has seen very little evolution over its 90 years lifetime. It was mostly produced in precious metal with a manual winding movement or in stainless steel with a quartz movement. However, the Reference 2390 was produced in stainless steel with a manual winding movement. This combination provides a sport allure, faithful to the original spirit of the piece, while keeping the highest horological standards.
