From left to right: father, son & grandson -- the original Beta21-quartz (left, 1972 sold by VanCleef & Arpels in New York and seen by AW; now in our museum;), the Warhol-owned successor Beta22-quartz (middle, 1973 and in the Piaget-museum;) and the new interpretation with an automatic-movement and a stone-dial (right, 2024;).

For some reason Piaget is not saying a word about their Beta21 (ref14101 & ref15101) and their story-telling of the "Warhol" begins with the successor Beta22 (ref15102)... :-)
