The original Tonneau was first introduced in 1906, just two years after the invention of the first men’s wristwatch. Bearing a tonneau-shaped case, the watch strongly reminds one of the tastes of the Art-Deco period. The present watch fitted in a heavy 18k pink gold case was made during the Cartier "Collection Privée Cartier Paris" period, a time when Cartier went back to their core principles from the "Quartz Era", with a renewed focus on design and mechanics. As a very important element for connoisseurs the present Cartier Tortue is highly desirable in the market today.
