The introduction of the C-shape case in the 1960s marked a significant design evolution, moving away from traditional round cases to a more integrated, fluid aesthetic. Equipped with the chronometer-certified Caliber 1001, this 1970 example reflects a period of robust mechanical development and distinctive styling within the Constellation family.
