Piaget

Possession

A gold ring that carries a second band, free to spin around the finger.

Zip

Van Cleef & Arpels

Zip

A working zip fastener in gold and stones: pull the tassel and the necklace closes up into a bracelet.

One moving part runs the length of a necklace; the other circles a finger. Van Cleef & Arpels had a jewelry zip patented in 1938, after the Duchess of Windsor's suggestion, and spent twelve years reaching the first necklace in 1950; a pull of the tassel turns it into a bracelet. Piaget's Possession, from 1990, is a smaller motion repeated all day: a second band turning freely around the first, credited to Yves G. Piaget and later chased with the Decor Palace texture of the house's watch dials.
