The first patented hermetic watch case ever produced was created by Jean Finger of Longeau, in Berne, Switzerland in January 1921. Registered with a patent number 89276, the watch came with a protective box (Montre a remontoire avec boitier protecteur), allowing thus to place the watch inside a bigger case with a screw-down bezel and making it 100% hermetic.

Different brands adopted this design and one of them was Eberhard, using a variety of materials. Our model in 14K gold is a rare example. The design was such a success that Mr. Wilsdorf (Rolex) bought the patent to use it for his 1^st Hermetic Watch (please see Lots 15 and 21 in our sale) in 1924, causing the other brands to discontinue their productions. That meant, that Eberhard was only able to produce watches with this design for less than 3 years.
