A ref. 96065 Tank Louis Extra Plate, from 1992. The 96065 is known as the 'Pre-CPCP', the last Tank Louis made before Richemonte acquired its controlling stake in 1993. It introduced the guilloché dial to the model as well as an ultra-thin Frederic Piguet ébauche, making the case even more svelte. Only a small fraction of production was optioned by special order in the 1990s to include this Grain de Riz bracelet, which adds a refinement to the Tank and gives it its own unique personality.
