5 Simple Steps: How to Remove the Back of a Rolex Watch

Rolex watch back removal

A Rolex watch is a luxury timepiece that is often passed down from generation to generation. However, over time, the watch may need to be serviced or repaired. One of the most common repairs is removing the back of the watch to access the movement. While this may seem like a daunting task, it is actually quite simple with the right tools and instructions. In this article, we will provide you with a step-by-step guide on how to remove the back of a Rolex watch.

Before you begin, it is important to gather the necessary tools. You will need a case opener, a pair of tweezers, and a soft cloth. You can purchase these tools online or at your local hardware store. Once you have the necessary tools, you can begin the process of removing the back of the watch. First, place the watch on a soft cloth to protect it from scratches. Then, use the case opener to carefully pry open the back of the watch. Be sure to apply even pressure around the entire circumference of the case to avoid damaging the watch. Once the back of the watch is open, you can use the tweezers to remove the movement. Be careful not to touch the movement with your fingers, as this could damage it.

With the movement removed, you can now access the inside of the watch. You can clean the movement, replace any damaged parts, or perform any other necessary repairs. Once you have completed your repairs, you can reassemble the watch by placing the movement back into the case and screwing on the back of the watch. Be sure to tighten the back of the watch securely to prevent water damage. Once the watch is reassembled, it is important to test it to ensure that it is working properly. You can do this by setting the time and winding the watch. If the watch is working properly, you can now wear it and enjoy it for many years to come.

Disassembling the Clasp

Removing the back of a Rolex watch requires careful disassembly of the clasp. Follow these detailed steps to avoid damaging the watch:

Locate the clasp screws: On most Rolex models, the clasp is secured by two small screws located on the underside. Use a small screwdriver with a flat head to gently loosen these screws.
Remove the clasp cover: Once the screws are loose, carefully lift off the clasp cover, revealing the inner workings of the clasp.
Identify the clasp spring bars: The clasp is held together by two small spring bars that run parallel to each other. Use a pair of tweezers to gently squeeze the ends of each spring bar, releasing the clasp from the watch band.
Separate the clasp components: Once the spring bars are released, the clasp should come apart into several components. Take care to note the orientation of each component for reassembly later.
Clean the clasp: While the clasp is disassembled, take the opportunity to clean any dirt or debris that may have accumulated. Use a soft cloth and mild detergent to gently wipe down all the components.
Reassemble the clasp: Once cleaned, reassemble the clasp by reversing the disassembly steps. Ensure that all components are securely in place and that the spring bars are fully engaged to prevent the clasp from detaching.
Tighten the clasp screws: Finally, use the screwdriver to tighten the clasp screws, ensuring that the clasp is securely attached to the watch band.

By following these steps carefully, you can safely disassemble and reassemble the clasp of your Rolex watch, enabling you to remove the back of the watch for maintenance or repairs.

Removing the Spring Bars

Spring bars are small, metal rods that are used to secure the watch band to the watch case. To remove the spring bars, you will need a spring bar tool. This is a small, forked tool that can be purchased at most jewelry stores or online.
Once you have a spring bar tool, follow these steps to remove the spring bars:
1. Locate the spring bars. They are typically located on the underside of the watch case, near the lugs.

2. Insert the spring bar tool into the notch on the spring bar. Make sure that the tips of the tool are facing inward, towards the center of the watch.

3. Compress the spring bar. Use your thumb to press down on the spring bar tool, compressing the spring bar.

4. Slide the spring bar out. Once the spring bar is compressed, you should be able to slide it out of the lug.

5. Repeat steps 2-4 for the other spring bar.

6. Once both spring bars have been removed, you can remove the watch band from the watch case.

Tips for Removing Spring Bars

If you are having difficulty compressing the spring bar, try using a pair of pliers.
Be careful not to lose the spring bars. They are small and can easily be lost.

If you are not comfortable removing the spring bars yourself, you can take your watch to a jeweler or watchmaker.

Spring Bar Sizes for Rolex Watches

Detaching the Caseback

Step 1: Secure the Watch

Place the watch face down on a soft cloth to prevent scratches. Secure it using a watchmaker’s vise or a similar tool.

Step 2: Identify the Caseback Type

Rolex watches typically feature two types of casebacks: snap-on and screw-in. Snap-on casebacks have notches around the edge, while screw-in casebacks are held in place by small screws.

Step 3: Using the Caseback Tool

**Snap-On Casebacks:**

Carefully align the caseback tool’s pins with the notches on the caseback.
Apply gentle pressure to the pins while simultaneously rotating the tool counterclockwise.
The caseback will gradually detach as you rotate the tool.

**Screw-In Casebacks:**

Use a small screwdriver to carefully unscrew the screws securing the caseback.
Once all screws are removed, gently pry the caseback off using a caseback knife or a small flat-head screwdriver.

Inspecting the Inner Seal

Once the case back is removed, it’s crucial to inspect the inner seal to ensure it’s in pristine condition. The inner seal is a rubber or silicone gasket that creates a watertight barrier between the case back and the movement. Over time, the seal can deteriorate due to exposure to moisture, chemicals, or extreme temperatures.

Inspect the seal carefully for any signs of damage, such as cracks, tears, or deformation. If you find any damage, it’s essential to replace the seal immediately. A compromised seal can allow moisture to penetrate the watch, potentially damaging the movement and compromising the watch’s water resistance.

To replace the inner seal, carefully remove the old seal using a small watchmaker’s screwdriver or a gasket removal tool. Clean the groove where the seal sits with a lint-free cloth dipped in rubbing alcohol. Apply a thin layer of silicone grease to the new seal and gently press it into place. Make sure the seal is seated correctly and flush with the case back.

Symptom	Possible Cause
Moisture inside the watch	Damaged inner seal
Reduced water resistance	Compromised inner seal

Identifying the Caseback Model

To identify the caseback model of your Rolex watch, you’ll need to examine the engravings on the caseback itself. The following steps will guide you through the process:

Locate the caseback: The caseback is the solid metal back of the watch that covers the inner workings of the movement.
Identify the caseback model number: Look for a series of numbers engraved on the caseback. This number represents the caseback model.
Check the caseback type: Rolex uses various types of casebacks, including solid casebacks, snap-on casebacks, and screw-down casebacks. The type of caseback will determine the method you need to use to remove it.
Look for a Rolex logo or crown: A genuine Rolex watch will have a Rolex logo or crown engraved on the caseback. This is an important indicator of authenticity.

Consult a watchmaker if necessary: If you are unable to identify the caseback model or type on your own, it is recommended to consult a professional watchmaker for assistance. They can accurately identify the caseback and provide guidance on the proper removal method.

Using the Proper Tool for Opening

To properly open the back of a Rolex watch, you will need the correct tool for the job. Rolex watches use a screw-down case back, which requires a special wrench to open. This wrench is specifically designed to fit the notches in the case back and prevent damage to the watch. If you do not have the proper tool, do not attempt to open the back of the watch yourself, as you may damage it.

Step 1: Gather Your Tools

In addition to the Rolex case back wrench, you will also need a clean, lint-free cloth and a pair of gloves. The gloves will help protect your hands from scratches and dirt.

Step 2: Prepare Your Workspace

Find a clean, well-lit workspace where you will not be disturbed. Spread out the lint-free cloth on your work surface to protect the watch from scratches.

Step 3: Position the Watch

Place the watch face down on the cloth. Position the Rolex case back wrench over the notches in the case back and turn it counterclockwise to loosen the case back.

Step 4: Remove the Case Back

Once the case back is loose, carefully lift it off the watch. Be careful not to touch the movement or the dial, as you may damage them.

Step 5: Inspect the Gasket

Once the case back is removed, inspect the gasket for any signs of damage or wear. The gasket is responsible for sealing the watch case and preventing water from entering. If the gasket is damaged, it must be replaced before you close the case back.

Step 6: Cleaning the Case Back and Gasket

Use a soft cloth to gently wipe away any dirt or debris from the case back and gasket. Be careful not to scratch the surfaces. If the gasket is dirty, you can use a cotton swab dipped in rubbing alcohol to clean it. Once the case back and gasket are clean, you can reassemble the watch.

Removing the Caseback Screw

To remove the caseback screw, you will need a caseback opener tool. This tool is specifically designed to fit the small notches in the screw head. Once you have the tool, follow these steps:

Place the caseback opener tool over the screw head and align it with the notches.
Apply gentle pressure and turn the tool counterclockwise to loosen the screw.
Once the screw is loose, carefully remove it from the watch.

If you don’t have a caseback opener tool, you can try using a pair of needle-nose pliers. However, be very careful not to damage the screw head or the watch case.

Once the screw is removed, you can carefully lift the caseback off of the watch. Be careful not to damage the gasket that seals the caseback to the watch case.

Securing the Caseback Screw

The final step in removing the back of a Rolex watch is to secure the caseback screw back into place. This should be done carefully to avoid damaging the watch or the screw. Here are the steps on how to secure the caseback screw:

Place the caseback screw in the hole in the caseback.
Use the tweezers to hold the screw in place.
Use the screwdriver to turn the screw clockwise until it is snug.
Tighten the screw further by turning it an additional quarter turn.
Check to make sure that the caseback is properly seated on the watch case.
Use a cloth to wipe away any fingerprints or smudges from the caseback.
Your Rolex watch is now properly assembled.

Here are some additional tips for securing the caseback screw:

Do not overtighten the screw, as this can damage the watch or the screw.
If you are having difficulty securing the screw, you can use a small amount of watch oil to lubricate the threads.
If you do not have a screwdriver that fits the caseback screw, you can take the watch to a jeweler or watchmaker to have it secured.

Step-by-Step Instructions:

Prepare your watch by removing the bracelet or strap.
Use the caseback removal tool to gently pry open the case back.
Inspect the old O-ring gasket for any damage or wear.
Remove the old O-ring using tweezers.
Clean the groove where the O-ring sits using a clean, lint-free cloth.
Apply a small amount of lubrication to the new O-ring.
Use tweezers to carefully place the new O-ring in the groove.
Ensure that the O-ring is seated properly and is not twisted or pinched.
Reinstall the case back using the caseback removal tool.
Tighten the case back securely, but do not overtighten it.

Tips:

Use a watchmaker’s loupe to inspect the O-ring and groove for any damage.
If you’re not comfortable replacing the O-ring yourself, take your watch to a qualified watchmaker.
Replace the O-ring every 2-3 years to maintain the water resistance of your watch.
