Rolex is unique for several reasons:
Oyster Case: This was the world’s first waterproof wristwatch case, introduced in 1926. The Oyster case is a significant innovation in watchmaking, providing superior water and dust resistance. Its construction involves screwing down the bezel, case back, and winding crown against the middle case.
Perpetual Movement: Rolex developed the first self-winding mechanism with a Perpetual rotor in 1931. This technology is at the heart of every modern automatic watch, allowing the watch to run continuously without manual winding, as it is powered by the movement of the wearer's wrist.
Materials: Rolex uses high-quality materials, including 904L stainless steel, which is more resistant to corrosion and rust. They also use their own formulations of gold and a highly scratch-resistant ceramic material called Cerachrom.
In-House Manufacturing: Rolex is known for manufacturing almost all components of its watches in-house, ensuring high-quality control and craftsmanship.
Chronometer Certification: Rolex watches are renowned for precision. Each Rolex watch is a certified Swiss chronometer, tested by the Swiss Official Chronometer Testing Institute (COSC).
Iconic Design: Rolex has created some of the most iconic watch designs, like the Submariner, Daytona, and Datejust, which have remained largely unchanged for decades, contributing to their timeless appeal.
The Rolex Oyster watch case back is a significant innovation in the world of watchmaking, primarily known for its enhanced water resistance and durability. The design and construction of the Oyster case back necessitate the use of specialized tools for opening, due to several key reasons:
Screw-Down Mechanism: The Oyster case back is distinctively designed with a screw-down mechanism. Unlike snap-back cases that can be pried open, the Oyster case back is threaded and screws directly into the case. This design ensures a watertight seal, which is crucial for the watch's water resistance.

Uniform Pressure Distribution: The screw-down design also aids in distributing pressure uniformly across the case back, enhancing the watch's ability to withstand deep-water pressures. This is particularly important for diving watches, where pressure resistance is a key feature.

Precision and Tight Sealing: The threads and seals on an Oyster case back require precise alignment to maintain water resistance. Specialized tools are designed to engage these threads accurately and apply the correct amount of torque, ensuring the case back is sealed tightly without damaging the threads or the watch.
Avoiding Damage: Rolex watches are luxury items made with high-quality materials. Using the correct tool minimizes the risk of scratching or damaging the case back or other parts of the watch. Incorrect tools or methods could lead to costly repairs or a voided warranty.
Specific Tool Design: The Oyster case back often features a unique pattern of grooves or notches around its perimeter. Specialized Rolex case opening tools are made to fit these patterns precisely, ensuring a secure grip and the ability to apply the necessary torque to open and close the case back safely.
Due to these factors, opening a Rolex Oyster case back is typically a task reserved for professional watchmakers or technicians who have the correct tools and training. This ensures the watch's integrity, especially its water resistance and mechanical functionality, is maintained. Unauthorized or improper opening of the case back can compromise these features and potentially void the watch's warranty.
