The following year, he came to register his own Oyster Case innovation. Wilsdorf purchased all rights to the patent from them When he saw their design, and then used elements of their screw-down crown design in his own Oyster case. Instead, it is based on a patent initially filed by Paul Perregaux and Georges Peret in 1925. Hans Wilsdorf, the founder of Rolex, did not actually invent the Oyster concept in its full. The Rolex Oyster case actually has an interesting history. Today, the front is not screwed to the case anymore, however, Rolex still makes fluted bezels for their Datejust model, all crafted in solid 18K gold, which can be seen as a nod to the past, apart from looking really good. This can be seen in the flutings of the bezel on the Oyster watch above. The first Oysters also had screw down on the front of the case to ensure water-resistance. To ensure water-resistance, the caseback of the Oyster watches is screwed down to the case and demands a special tool exclusive to authorized Rolex watchmakers, so only they can access the movement. Some cases, for example, feature crown guards, whilst some cases are much thinner.īut what they have in common is the way the cases are assembled to allow for water-resistance. Just because a Rolex has an Oyster case, however, doesn’t mean that all of these cases are identical in design. This solid middle case works as the backbone for all of the other parts and ensuring that these are securely fitted. The Oysters have a solid middle case which is stamped and machined out of a solid block of either Oystersteel, 18 ct gold or platinum (depending on the watch model). The Rolex Oyster case guarantees water-resistance to a depth of at least 100 meters (330 feet), and up to 3,900 meters (12,800 feet) for the Rolex Deepsea extreme divers’ watch. Unlike what many people believe, Rolex ”Oyster” is not a model itself, but rather, as mentioned, a case structure that is meant to keep the movement safe from water.įor example, you can find ”Oyster Perpetual” on the dial of a Rolex Datejust, but the model is ”Datejust”. This means that the Cellini range of watches do not use the Oyster case – which of course may not be a surprise considering that is a very slimmed dress watch. The Oyster case is used for all Rolex’s watches that are water-resistant up to 100 meters. In Rolex’s own words, the Oyster case is a symbol of robustness and waterproofness. The first Rolex to feature this case structure was of course named “Oyster”. The Oyster case was invented by Rolex in 1926 and came to become the world’s first waterproof case for a wristwatch thanks to the patented concept of screwing down the bezel as well as the case back and the winding crown against the middle case. The tight closure of the Oyster’s shell can, of course, be symbolic to the watertight seals that are used in the Rolex Oysters, and can also refer to the aquatic habitat that Oysters have, symbolic to Rolex Oyster’s ability to withstand water. The legend has it that the name came about when Hans Wilsdorf, one night at a dinner party, struggled to open up an oyster. There is a legend about how the Rolex Oyster name came about. Thanks to the new Oyster case innovation, Rolex now offers watches that keep the movement safe from any dust or water. As you know, even just a tiny bit of water is dangerous for a watch movement, and can completely destroy a watch. The Oyster case is a symbol of waterproofness and symbolizes an important milestone in Rolex’s and watchmaking’s history. The term refers to the ”Oyster case” that Rolex uses for most of its watches.
