2917, CPCP Tank Louis Dual Time, White Gold Cartier NSO Urwerk revisited those first stepsA ref. 2917 Tank Louis Dual Time in white gold, one of the rarest CPCP models from the final years of the collection. The 2917 features a dual rosette guilloch dial, case under 6mm thin, and Piaget bauche calibre 9901 MC which allows all functions to be adjusted through one cabochon crown. The Tank Louis Dual Time rarely surfaces and to date has never appeared at a large auction house. It is a fittingly beautiful and complicated goodbye to the CPCP
