Jack de Boucheron

A supple gold cable closed by a faceted clasp shaped like an audio jack, wrapped once or three times round the wrist or opened out as a necklace or belt.

Tiffany Lock

A bangle drawn as the elongated shackle of a padlock, whose clasp swivels and clicks shut like the lock it imitates.

Four gold bangles introduced Tiffany Lock in August 2022, each drawn as the long shackle of a padlock with a clasp that swivels and clicks shut. Jack de Boucheron, from 2019, treats its closure more freely: a faceted plug modelled on an audio jack joins a gold cable supple enough to coil three times round the wrist or hang as a sautoir. Tiffany found its precedent in an 1883 brooch made for a couple; Boucheron needed none beyond the headphone lead.
