While the turnlock itself is not a patented design feature, it is probably most closely aligned with Hermes. The turnlock is the closure for many of the house’s iconic bags and bracelets, such as the Kelly Dog and others.

This is a popular motif this season; Michael Kors did quite a few bracelets that bear a striking resemblance to Hermes designs (and Cartier); here, Ricardo Tisci for Givenchy offers a leather bracelet with what the company is calling a “shark lock” closure. The leather bracelet comes in red and black, and sells for €406.12 at Luisa Via Roma.
