How to Open a Rado Diastar Watch

Rado Diastar watches are known for their durability and sleek design, but they also come with a challenge: opening them for maintenance or battery replacement. Understanding how to safely open your Rado Diastar watch is crucial to avoid damaging the intricate mechanisms or the iconic sapphire crystal that the brand is known for. Whether you are a professional watch technician or a DIY enthusiast, following the correct procedure is important. This article will guide you through the steps to properly open a Rado Diastar watch and discuss the tools you will need, potential risks, and tips for ensuring your watch stays in excellent condition after opening. Let's delve into the details and master the skill of opening this prestigious timepiece.

Understanding the Rado Diastar Watch Construction

The Rado Diastar watch features a unique construction that sets it apart from other watches. Its case is typically made from hardmetal, a durable material that is scratch-resistant. Additionally, the watch features a sapphire crystal that is nearly impervious to scratches, which is a hallmark of the Diastar design. This robustness, while desirable, can make the watch tricky to open, especially for those unfamiliar with its layout. The back of the watch is often a snap-on case, although some models may feature a screw-down case back.

Before you begin the process of opening your Rado Diastar watch, it’s essential to gather the necessary tools and prepare yourself for the procedure. Rushing through this process without the correct tools can result in damaging the watch, leading to costly repairs.

Tools Required

To safely open a Rado Diastar watch, you will need the following tools:

1. Watch case opener: This tool is designed specifically for prying open snap-on case backs or loosening screw-down case backs.
2. Watchmaker's knife: A thin blade used to pry open the back of the watch carefully.
3. Case holder: This keeps the watch steady as you work on opening it, preventing any unnecessary movement.
4. Screwdriver set: If your Rado Diastar has a screw-down case back, you will need precision screwdrivers to remove the screws.
5. Rubber ball: In some cases, a sticky rubber ball can be used to twist off a screw-down case back, providing the grip needed without scratching the watch.
6. Soft cloth: A cloth to protect the surface of your watch and prevent scratches while working.

Step-by-Step Guide to Opening the Watch

1. Prepare Your Workspace

Before beginning the opening process, ensure that your workspace is clean and well-lit. Lay down a soft cloth to prevent any scratches to the watch surface. Organize your tools so that everything is easily accessible. Proper preparation can make the process more manageable and reduce the risk of damaging the watch.

2. Identify the Case Back Type

Rado Diastar watches primarily come with two types of case backs: snap-on and screw-down. Identifying the type of case back on your watch is the first step in determining how to proceed.

• Snap-On Case Back: This type of case back is common on Rado Diastar watches and is held in place by pressure. You can usually recognize it by the lack of screws.
• Screw-Down Case Back: This case back is screwed into place and often has small notches around the edge that indicate it needs to be twisted off.

3. Using a Watch Case Opener (Snap-On Case Back)

If your Rado Diastar has a snap-on case back, follow these steps:

• Step 1: Place the watch in the case holder to prevent any movement.
• Step 2: Insert the watchmaker's knife or case opener tool into the small gap between the case back and the watch case.
• Step 3: Carefully apply pressure to pry open the case back. Do this slowly to avoid any sudden movements that could damage the watch.
• Step 4: Once the case back is slightly lifted, continue to work around the edge until the entire case back pops off.

4. Using a Watch Case Opener (Screw-Down Case Back)

If your Rado Diastar features a screw-down case back:

• Step 1: Place the watch face down in the case holder, ensuring that it is secure.
• Step 2: Use the case opener tool or rubber ball to grip the back of the case. Turn the tool counterclockwise to loosen the case back.
• Step 3: If the case back is particularly tight, use a precision screwdriver to unscrew it.
• Step 4: Once loosened, carefully remove the case back to reveal the inner workings of the watch.

Handling the Interior Mechanisms

Opening the watch gives you access to the movement, which is the heart of the timepiece. It’s essential to handle the interior components with care, as even a slight disturbance can affect the watch's performance.

Battery Replacement

For quartz Rado Diastar models, the most common reason for opening the watch is to replace the battery. Here are the steps for safely replacing the battery:

1. Locate the battery compartment within the movement.
2. Use a small screwdriver to remove the battery holder, if present.
3. Gently remove the old battery using plastic tweezers to avoid shorting the movement.
4. Insert the new battery in the correct orientation.
5. Reassemble the battery holder and ensure everything is secure before closing the case back.

Servicing the Movement

If you are opening the Rado Diastar to service the movement, it is highly recommended to take the watch to a professional. The movement of a watch is intricate and requires specific knowledge and tools for proper maintenance.

Closing the Case Back

After performing any necessary work inside the watch, it's time to close the case back.

• For Snap-On Case Backs: Align the case back with the watch case and press firmly with your thumbs until it snaps into place. Be sure to apply even pressure around the edges.
• For Screw-Down Case Backs: Align the case back and screw it in place using the case opener tool or rubber ball. Ensure that it is securely fastened but do not overtighten, as this can damage the threads.

Common Mistakes to Avoid

• Using the wrong tools: Using improper tools can lead to scratches, stripped screws, or even broken components. Always use the correct tools for the job.
• Forcing the case back: Applying too much force when opening or closing the case back can result in damage. Patience and a steady hand are key.
• Not protecting the watch face: Always work on a soft surface and consider covering the watch face with a soft cloth while working on the back to avoid accidental scratches.

Conclusion

Opening a Rado Diastar watch is a delicate task that requires precision and patience. By following the steps outlined in this guide and using the proper tools, you can safely open your watch for battery replacement or servicing. If you are ever in doubt or encounter difficulties, it’s best to consult a professional watchmaker to ensure your timepiece remains in excellent condition. Taking the proper precautions will help you maintain the longevity and performance of your Rado Diastar watch.
