Opening the case back of a Rolex watch, particularly those with the Oyster case, can seem daunting. The intricate design and the potential for damage make it a task best left to professionals. However, for experienced watch enthusiasts who understand the risks and possess the necessary tools, opening the case back can be manageable. This article delves into the process, focusing on the use of a Rolex EZ Oyster opener – a tool designed to facilitate this delicate procedure. We'll explore suitable tools, techniques, and crucial safety precautions.
Understanding the Rolex Oyster Case and the Need for Specialized Openers
Rolex's Oyster case, renowned for its water resistance and durability, employs a robust system to secure the case back. Unlike simpler snap-on backs, the Oyster case utilizes a precisely engineered screw-down system, often requiring significant force to open. Attempting to open it with inappropriate tools can lead to scratches, dents, or even damage to the case back or the movement itself. This is where a specialized opener, such as a Rolex EZ Oyster opener, becomes indispensable. The term "Rolex EZ Oyster opener" is a colloquialism; there isn't a specific Rolex-branded tool with that exact name. Instead, watchmakers and enthusiasts use this term to refer to the type of opener suitable for this task, often resembling the Bergeon 5700.
The Tool of Choice: The Bergeon 5700 (and its Alternatives)
The Bergeon 5700 is widely considered the gold standard for opening Oyster case backs. Its design incorporates features that minimize the risk of damage:
* Precise Jaws: The jaws of the Bergeon 5700 are meticulously crafted to grip the case back securely without marring the surface. The precise fit reduces slippage, preventing accidental scratches or damage during the opening process.
* Ergonomic Design: The tool's handle is ergonomically designed for comfortable and controlled operation, reducing the chances of applying excessive force.
* Durable Construction: Made from high-quality materials, the Bergeon 5700 is built to withstand repeated use without bending or breaking.
While the Bergeon 5700 is the preferred choice, budget-conscious enthusiasts often opt for less expensive alternatives. Many inexpensive copies of the Bergeon 5700 are available. While these copies will function, the quality of materials and precision engineering often fall short. The author's experience highlights this difference – having used a copy before upgrading to the genuine Bergeon 5700, the difference in quality, precision, and ease of use is significant. The knockoff, while functional, lacks the precision and robustness of the genuine article. Therefore, while a copy can work in a pinch, investing in the authentic Bergeon 5700 is highly recommended for long-term use and to minimize the risk of damaging your valuable Rolex.
Beyond the Opener: Essential Accessory – The Speed Wrench
The Bergeon 5700, or its equivalent, is only one part of the equation. Successfully opening a Rolex case back also requires a speed wrench. This tool is crucial for applying the necessary torque to loosen the case back without risking damage. A speed wrench is a small, hand-held tool with a rotating head that fits onto the opener's shaft. It provides leverage and control, ensuring a smooth and even application of force. Using a speed wrench prevents accidental slippage and ensures the case back is removed without causing damage. A poorly chosen speed wrench, or even using excessive force with a good one, can still cause problems, so careful application is key.
