Step-by-Step Guide to Changing the Pumps on a Rolex Watch

A Rolex watch is a luxury item that is prized for its precision and durability. While it is designed to last for many years, it is still important to keep it in good working order. One of the components that may need to be changed over time is the pump. The pumps in a Rolex watch are responsible for controlling the flow of oil within the movement, which helps to ensure that the watch runs smoothly and accurately.

Before you start the process of changing the pumps in your Rolex watch, it is important to gather all of the tools and materials that you will need. You will need a set of watchmaker's screwdrivers, a loupe or magnifying glass, a small brush, and a container of oil. It is also a good idea to have a clean, well-lit workspace where you can lay out all of your tools and materials.

The first step in changing the pumps in your Rolex watch is to remove the back cover. This can typically be done by using a screwdriver to unscrew the screws that hold the cover in place. Once the cover has been removed, you should use a loupe or magnifying glass to inspect the inside of the watch. Look for any signs of damage or wear and tear, such as cracks or chips in the metal, or signs of corrosion. If you notice any of these issues, it is best to seek professional help in order to repair them before proceeding with the pump change.

Once you have inspected the inside of the watch, you can begin to remove the old pumps. The pumps are typically located near the balance wheel and are held in place by screws. Use your screwdrivers to carefully remove the screws, being careful not to damage the screws or the metal of the watch. Once the screws have been removed, you can gently lift out the old pumps and set them aside.

Next, you will need to clean the inside of the watch. Use a small brush to carefully remove any debris or oil that may have accumulated inside the watch. This will help to ensure that the new pumps are able to function properly.

Once the inside of the watch has been cleaned, you can begin to install the new pumps. The new pumps will typically come pre-oiled, so you will not need to add any additional oil at this time. Simply place the new pumps into the same positions as the old pumps, and use your screwdrivers to secure them in place.

After the new pumps have been installed, it is important to test the watch to make sure that everything is functioning correctly. Start by turning the crown to wind the watch, and then let it run for a few minutes. Check the time to make sure that it is accurate, and also check for any signs of oil leaks or other issues.

If everything is working correctly, you can then replace the back cover and screw it back into place. Your Rolex watch should now be running smoothly and accurately, and you can enjoy it for many years to come.


Changing the pumps in a Rolex watch is a relatively simple process that can be done at home with the right tools and materials. However, it is important to be careful and precise, and to seek professional help if you encounter any problems along the way. With a little care and attention, you can keep your Rolex watch in top working order for many years to come.
