Cartier Paris Tonneau Dual Time 18kt Yellow GoldThe Cartier Tonneau is named so for its barrel shaped case; tonneau being French for barrel. In our minds the Tonneau is a very classy watch and this example is extra special thanks to its dual time format driven by two separate movements displayed on one Cartier Paris dial. The 46 x 26mm yellow gold case remains in very good condition. The cream colored dial is signed Paris and has two separate dial layouts with different Roman numeral arrangements.
