This is a great bracelet with a very important provenance. It was made in 1936 by Van Cleef And Arpels as part of their "Cadena" collection. That makes it already special because the design is extremely daring and sets the grounds for the next to come "Retro" style in the 1940's. It has an inscription that says: " For their 3 anniversary, 12.III.36, and Our tub, 17.III.36". According to Sotheby's, this bracelet was part of the inventory of the Duchess of Windsor jewels, so it must have been a gift from the Duke of Windsor, actually at that moment he was in fact King Edward VIII.
The Duchess of Windsor gave this watch/bracelet to Aline Griffith, Condesa Vda. de Romanones, and it is one of the pieces that Sotheby's Geneva will be auctioning on May 17th.
