The Tank Chinoise was originally launched in 1922, its case design with raised overlapping bars to the ends is an alteration from the classical Tank wristwatch. Imitating the architecture of Chinese temples, its perfectly symmetrical crossbars and sides from a square opening, symbolizing an open door to an inner space.
The large version of the Tank Chinoise mainly available in gold, models in platinum, such as the present watch, are exceedingly rare.
The 1920 model is described and illustrated in Cartier - The Tank Watch by Franco Cologni, p. 187.
