A closed back is part of the Oyster Perpetual Oyster case design. The result is that rust damage goes undetected. Rust on your Rolex Oyster Perpetual can only be detected by an expert watchmaker during a Rolex Service, when the watch is disassembled.
As for the Cases and Straps of Rolex Oyster Perpetual Oyster watches, they are made from a high-grade and rust-resistant steel. Your Rolex Oyster Perpetual movement can develop invisible rust damage when condensation gets into the movement. All Rolex Oyster Perpetual watches should be serviced every twelve months if they are worn by swimmers.
Rolex Oyster Perpetual watches are water-resistant thanks to the rubber seals on gaskets. Rolex Oyster Perpetual gaskets need to be changed since they are wearable components. Wear and tear on rubber gaskets make them less effective, thereby increasing the risk of condensation and moisture damage.
Some Rolex models are now covered by a 10-year watch service warranty instead of the standard 5-year warranty. Due to this ten-year service warranty, many Rolex Oyster Perpetual watch owners assume their watches need to be maintained every ten years. However, when you wear a Rolex Oyster Perpetual when bathing, showering, or swimming, that's not the case.
A Rolex Oyster Perpetual movement may be damaged if condensation breaks through the Oyster case and remains inside.
Before you dive into the water with the Rolex Oyster Perpetual, make sure the crown is securely attached.

- Make sure you test the water resistance of your Rolex Oyster Perpetual every year.
- It is imperative that the Rolex Oyster Perpetual be serviced immediately if it fails the test.
- The cost of repairing a Rolex Oyster Perpetual movement can be quite high, in my view, very expensive.
- It is unusual to see any visible rust damage on the outside a Rolex Oyster Perpetual.
