A ref. 2916 Tank Louis Dual Time in pink gold, one of the rarest CPCP models from the final years of the collection. The 2916 features a dual rosette guilloché dial, case under 6mm thin, and Piaget ébauche 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. It is a fittingly beautiful, elegant, and complicated goodbye to the CPCP years.
