An ordinary shape, reconsidered.

Published 21 October 2026 · WHV · Public-source editorial note

You recognise the nail before you recognise the jewellery. That small reversal is the point of Juste un Clou. Aldo Cipullo developed the idea for Cartier New York in the early 1970s, keeping the head, shaft and pointed end legible while turning a piece of everyday hardware into something that follows the wrist.

Recognition is part of the pleasure

The transformation is more exact than simply making a nail in gold. Scale, curvature and the relationship between the two ends determine whether the familiar object becomes convincing jewellery. The design also offers an alternative to a gemstone-led centrepiece: the recognisable shape carries much of the visual identity, including in versions without diamonds.

Its continued presence makes it possible to encounter the idea through contemporary production rather than needing an early example. That is a different proposition from collecting a documented period piece. The archival campaign photograph here identifies a later bracelet, not a 1971 original. Metal, dimensions, stone setting and opening method can vary between versions.

The version matters

Try the exact model and ask Cartier to demonstrate how it should be opened, worn and removed. For a pre-owned example, establish identity, condition and service history with a qualified specialist. A recognisable design is not a substitute for authentication. The WHV interest is an authored way of seeing that can remain part of daily life, without pretending the purchase price is simply the value of its gold.
