Determine Watch Type
Identifying the type of Rolex watch you have is crucial before attempting to open the back. Rolex watches come in various models, each with unique case designs and features. Here’s how to determine your watch type:
Check the Reference Number
Rolex watches have a unique reference number engraved on the case back or between the lugs at 6 o’clock. This number is a combination of letters and numbers, such as 116500 or 16610. You can use the reference number to identify the specific model and year of your watch.
Examine the Caseback
Rolex’s casebacks can vary significantly depending on the model. There are three main types you may encounter:
Screw-Back Case:
The case is secured to the watch head by screws. You will need a special tool or a watchmaker to open this type of caseback.
Snap-On Case:
The caseback is held in place by pressure-fitting it onto the watch head. It can be removed by carefully using a knife or a thin object to pry it open.
Exhibition Caseback:
This transparent caseback allows you to view the movement inside the watch. It is usually secured by screws and requires a special tool to open.
Measure the Case Diameter
Use a caliper or ruler to measure the diameter of the watch case, excluding the crown. This will help you narrow down the possible models of your watch.
Reference a Catalog or Online Database
Consult a Rolex catalog or an online database to match the characteristics of your watch with a specific model. This can provide further confirmation of the type of watch you have.
Choose a Back Case Opener
The type of back case opener you choose will depend on the specific model of Rolex watch you have. There are two main types of back case openers: a manual opener and a professional opener. A manual opener is a simple tool that can be used to open most Rolex watches. It consists of a handle and a set of jaws that are inserted into the notches on the back of the watch case. To use a manual opener, simply turn the handle clockwise until the back case pops open.
A professional back case opener is a more specialized tool that is typically used by watchmakers and jewelers. It is more expensive than a manual opener, but it offers a number of advantages. First, professional back case openers are designed to fit a wider range of watch models. Second, they are made of higher quality materials and are less likely to damage the watch case. Third, professional back case openers are often easier to use than manual openers.
If you are not comfortable opening the back of your Rolex watch yourself, it is best to take it to a watchmaker or jeweler. They will have the right tools and experience to open the watch safely and without damaging it.

To ensure proper water resistance, it is important to replace the original case back gasket with a new one. The gasket is a rubber or silicone seal that prevents water from entering the watch case. Over time, the gasket can become worn or damaged, so it is important to replace it regularly.
To replace the case back gasket, simply remove the old gasket and replace it with a new one. Make sure that the new gasket is the correct size and shape for your watch. You can find replacement case back gaskets online or at your local watchmaker.
Once the new gasket is in place, you can replace the case back. Start by threading the case back onto the watch case. Then, use the case back wrench to tighten the case back until it is snug. Be careful not to overtighten the case back, as this can damage the watch.
To ensure proper water resistance, it is important to test the watch after replacing the case back. Place the watch in a glass of water for 30 minutes. If there is no water inside the watch after 30 minutes, then the watch is water resistant.
Replacing the case back on your Rolex watch is a simple process that can be completed in a few minutes. By following these steps, you can keep your watch water resistant and looking great for years to come.
Tighten the Case Back Securely
Now that the case back is clean and free of any debris, it’s time to tighten it securely. Here’s a step-by-step guide to ensure your Rolex watch is water-resistant once more:
- Screw the case back onto the case: Align the case back with the case and carefully screw it on by hand. Avoid overtightening.
- Use a case back wrench: Once the case back is hand-tight, use a case back wrench to tighten it further. Turn the wrench slowly and evenly to ensure the case back is seated correctly.
- Tighten to the correct torque: Refer to the torque specifications provided by Rolex for your specific watch model. Using a torque wrench, tighten the case back to the specified torque value.
- Check the water resistance: Once the case back is tightened, test the water resistance of the watch using a pressure test kit.
