Designed in 1935, the Cadenas <b>watch</b> from <a href="http://www.selfridges.com/GB/en/cat/van-cleef-arpels" style="text-decoration: none"><font color="black"><b>Van Cleef & Arpels</b></font></a> represents strength through its lock-like design, reflecting the union of two families and rumoured to have been at the-then Duke and Duchess of Windsor&#39;s request. Today, its white gold case has been studded with 233 diamonds, sitting atop a black alligator leather strap that highlights the luxurious and iconic shape of the house&#39;s most famous watch creation.
