The innovative Rolex Oyster casing has been in the limelight for a long time, and for very good reasons. It is regarded as one of the most inventive and significant improvements to the timepiece. Today we will discuss the horological history and help you comprehend the watch better.

Rolex Oyster

The Rolex Oyster was the world’s first practical dust-proof and waterproof timepiece casing, and it changed the watch business in more ways than one. It not only ensured the wristwatch’s metamorphosis from a delicate female adornment to a strong men’s accessory, but it also successfully became a symbol of robustness which is quite impressive. The case has withstood the test of time, so much so that the word Oyster is now inscribed on the dial of the most of modern Rolex watches.

What the Oyster Case Is All About!

The Rolex Oyster case is constructed with hermetical seal to ensure water-resistance up to 300 metres for the Submariner & Submariner Date watches, 3,900 metres for the Deepsea collection & 1,220 metres for the Sea-Dweller. It also has a solid central casing made from a solid block of Oystersteel, 950 platinum or 18k gold, that has been stamped. The centre portion, which serves as the case’s backbone, is exceptionally strong and provides a solid fit for the entire case construction.

The crown guard, which is positioned on the side of the centre block to form an essential part of the case construction. It is a feature seen primarily on Professional models. The sapphire crystal is placed on a gasket that fits precisely against the case’s flange, enhancing the Oyster case’s water-proof and dust-proof properties.

All About Cylops Lens:

The “Cylops” lens on the sapphire crystal is one of the Oyster case’s outstanding features. The Cyclops lens, named after the one-eyed giants of Greek mythology, was invented in the early 1950s. Its primary purpose on several Oyster models is to allow the enlargement of dates. This unique feature to the crystal allows the user to easily see the date. Rolex was fast to issue a warning to any companies who planned to use same features.

Triplock & twinlock Crown of Thorns:

The Triplock & Twinlock winding crowns are patented features of the Oyster casing that were created to assure its great water resistance. They were released in 1953 and 1970, respectively. This aspect of the Rolex Oyster case’s construction earned Rolex watches a reputation for being among the most effective waterproof case architectures to date.

The two winding crowns are readily accessible for the Submariner and Submariner Date, Deepsea divers, and Sea-Dweller watches and are made up of about ten components that give maximum waterproof security comparable to a hermetic seal of a submarine’s hatch. The & Triplock and Twinlock Winding Crowns come in three different metals: oystersteel, 950 platinum and 18k gold.

The Display of Chromalight:

The Oyster casing was designed for maximum water-proofness and dust resistance and was with the models that were primarily diving watches at that time. As a result, it was critical to provide Rolex consumers with a function that allowed them to operate the watch in low-light situations like underwater. Rolex began utilising a new luminous material called Chromalight to meet this demand. This material, which generates a blue glow, provides increased visibility and a longer period of vision in low-light settings.

Cerachrom Bezel & The Insert:

When Rolex began developing the Oyster case, it recognised in addition to the case’s toughness, the bezel is one of the most prominent components of the watch that is disposed to to external corrosion. As a result, in 2005 Rolex developed and patented the Cerachrom bezel inlay for select Professional models in the Oyster collection. The Cerachrom bezel and inlay are constructed of corrosion-resistant ceramic that is highly durable. It also has 100% colour retention and great polish-ability.
