From the collection of Pharrell Williams, Imperiale Diamond Watch

The Imperiale comes from Chopard's signature ladies' collection, introduced in 1994 under the creative direction of Caroline Scheufele and built around the four decorative amphora-form pillars set into the case flanks, the crown-like architectural detail that has carried the design language of the line through every iteration since. This reference (37/3260-20T) is the diamond-set high jewelry treatment of the Imperiale, executed in 18-karat white gold.

The dial is fully diamond-paved with radiating diamond baguettes around a central Chopard Genève signature, framed by a bezel channel-set with baguette diamonds. Each of the four amphora pillars is pavé-set with baguette diamonds and finished with white gold conical terminals. The watch face comes with a black alligator strap with matching 18-karat white gold buckle set with square-cut diamonds. Accompanied by original papers.
