Structure of layers

The middle part of the Oyster case (the middle part of the case) is made of 904L stainless steel, 18ct gold or platinum, made by printing and machining. It is durable and has become the backbone of other components. Some professional models are equipped with side crown shoulder guards, which are essential to the middle case.

Screw in the bottom cover

The oyster bottom is tightly screwed into the middle case, so it is fully sealed. The distinctive pit pattern on the bottom is derived from the 1926 Oyster replica watch. Only authorized Rolex watchmakers can assemble the movement with specific tools.

The original oyster-type outer triangle pit pattern has a practical use: these pit patterns help the external ring screw fixed on the case to ensure the waterproof performance of the replica watch. The pit-patterned design of the bottom cover is based on the same considerations and is fastened to the topic with a specific Rolex tool. Today, however, the pit has become an aesthetic design element and one of the actual Rolex characteristics.

Since its birth, Rolex's classic oyster case design has been passed down to this day, although some details have been fine-tuned. But the overall design has stayed the same.
