After doing some reading on Dunhill and their new creative director, Kim Jones, I noticed he was wearing this exceptional piece in a GQ photoshoot. The Key Watch was dug up from the Dunhill archives with some slight modifications from the 1937 original.

Details: The watch casing is made of sterling silver, but for the key portion, brass was used for strength so as not to break off in the lock. The timepiece movement is provided by Jaeger-LeCoultre.
