If you’re new to watch repair, removing a watch stem can seem like a daunting task. However, with the right tools and a little bit of patience, it’s a relatively simple procedure. In this guide, we’ll walk you through the steps of how to remove a watch stem safely and easily.
Before you begin, gather the following tools: a pair of tweezers, a small screwdriver, and a watchmaker’s loupe. You may also want to have a small piece of tape or putty on hand to help you keep track of the small parts. Once you have your tools assembled, you’re ready to get started.
The first step is to remove the watch crown. This is usually done by unscrewing the crown counterclockwise. Once the crown is removed, you’ll see the stem sticking out of the movement. Gently grasp the stem with the tweezers and pull it straight out. Be careful not to bend or damage the stem.
Gather Your Tools
Removing a watch stem requires specialized tools to prevent damage to the delicate components. Here’s a comprehensive list of the essential tools you’ll need:

Identify the Watch Stem
The watch stem is the small, cylindrical piece that protrudes from the side of the watch case. It is used to wind the watch, set the time and date, and stop the watch. The watch stem is typically made of metal, and it is often knurled for a better grip.
To identify the watch stem, look for a small, cylindrical piece that protrudes from the side of the watch case. It is usually located near the 3 o’clock position. The watch stem may be knurled for a better grip.
Here is a table of the different types of watch stems:
| Type of Watch Stem | Description |
|---|---|
| Screw-down | The screw-down watch stem is the most common type of watch stem. It is screwed into the watch case, and it must be unscrewed before it can be removed. |
| Push-pull | The push-pull watch stem is a type of watch stem that is pushed in or pulled out to perform different functions. |
| Bayonet | The bayonet watch stem is a type of watch stem that is attached to the watch case with a bayonet mount. |
Remove the Crown Guard
The crown guard is a small metal piece that protects the crown from being accidentally knocked or pulled out. To remove the crown guard, you will need a small screwdriver or a watchmaker’s knife.
1. Insert the screwdriver or knife into the small slot on the side of the crown guard.
2. Gently pry the crown guard away from the watch case.
3. If the crown guard is stuck, you can try using a small amount of penetrating oil to loosen it. Apply the oil to the slot on the side of the crown guard and let it sit for a few minutes before trying to pry it off again.
