Removing a watch stem is a delicate procedure that requires patience and precision. The stem is a small, metal rod that connects the watch’s movement to the crown, allowing the wearer to set the time and wind the watch. If the stem is damaged or broken, the watch will not function properly. In this article, we will provide a step-by-step guide on how to remove a watch stem safely and effectively.
Before you begin, gather the necessary tools. You will need a pair of tweezers, a small screwdriver, and a magnifying glass. If you do not have these tools, you can purchase them at a hardware store or online. Once you have gathered your tools, find a clean, well-lit workspace. It is important to have good lighting so that you can see what you are doing.
To remove the watch stem, first use the tweezers to gently pull out the crown. The crown is the small, round knob on the side of the watch that is used to set the time and wind the watch. Once the crown is removed, you will see the stem. Use the screwdriver to gently pry the stem out of the movement. Be careful not to damage the movement or the stem. Once the stem is removed, you can now repair or replace it.
Preparing the Watch
Prior to removing the watch stem, meticulous preparation is paramount to ensure the watch’s integrity and prevent any potential damage. This preparatory phase encompasses several crucial steps:

Once the crystal is removed, the watch movement can be gently lifted out of the case using tweezers. Handle the movement with care to prevent damage to its delicate components.
Evaluating the Type of Watch Stem
Determining the type of watch stem is crucial before attempting its removal. Watch stems can vary in size, design, and complexity, and the appropriate removal technique depends on the stem’s characteristics.
To evaluate the watch stem, carefully observe its diameter, shape, and any distinctive features. Here are some common types of watch stems:
Standard Stem
Standard stems are the most common type found in basic watches. They have a cylindrical shape with a diameter typically ranging from 0.8mm to 1.2mm. Standard stems are usually equipped with a simple lever that engages the movement’s crown.
| Stem Diameter | Lever Type |
|---|---|
| 0.8mm to 1.2mm | Simple lever |
Thin Stem
Thin stems are less common and are often used in sleek or smaller watches. Their diameter is usually below 0.8mm, making them more delicate and requiring a more precise removal technique.
| Stem Diameter | Lever Type |
|---|---|
| Below 0.8mm | May vary (delicate lever) |
Threaded Stem
Threaded stems are a specialized type that employs a screw-on mechanism to secure the crown. They typically have a wider diameter and a threaded surface that mates with the inside of the crown. Threaded stems require a different removal approach, as they need to be unscrewed rather than pulled out.
| Stem Diameter | Lever Type |
|---|---|
| Wider than standard stems | N/A (Screw-on mechanism) |
Selecting the Appropriate Tools
The most crucial step in removing a watch stem is selecting the appropriate tools. The wrong tools can damage the watch and make the process more difficult.
1. Watchmaker’s Screwdriver
A watchmaker’s screwdriver is a small, precision screwdriver designed specifically for working on watches. It has a thin, tapered shaft and a magnetic tip that holds the screw in place.
2. Case Knife
A case knife is a thin, flexible knife used to pry open the case of the watch. It should be sharp enough to cut through the glue that holds the case together, but not so sharp that it damages the watch.
3. Hand Removal Tool
A hand removal tool is a specialized tool designed to remove the hands of the watch without damaging the dial or movement. It has a forked end that fits over the hand and a spring-loaded mechanism that allows the hand to be lifted off the spindle.
Here is a more detailed description of the hand removal tool:
| Tip | Description |
|---|---|
| Spring-loaded | Applies even pressure to lift the hand off the spindle without damaging it. |
| Forks | Fit securely around the hand to grip it firmly. |
| Precision construction | Ensures a precise fit and prevents damage to the delicate watch components. |
4. Tweezers
Tweezers are used to hold small parts, such as screws and springs, during the removal process. They should be non-magnetic to avoid attracting metal parts.
Securing the Watch
Before you can remove the watch stem, you need to secure the watch. This will prevent the watch from moving around and make it easier to work on. There are a few different ways to secure a watch:
1. Use a watchmaker’s vise
A watchmaker’s vise is a specialized tool that is designed to hold watches securely. It has two jaws that can be adjusted to fit the watch and a base that can be clamped to a table or workbench.
2. Use a piece of leather or rubber
If you don’t have a watchmaker’s vise, you can use a piece of leather or rubber to secure the watch. Simply wrap the leather or rubber around the watch and then clamp it to a table or workbench.

Disengaging the Setting Lever
In the context of a watch movement, the setting lever is an essential component that allows the user to conveniently adjust the timepiece’s parameters. Its primary role is to facilitate the transfer of rotational motion from the crown to the gear train, providing the means to advance or retard the hands accordingly.
However, certain circumstances may necessitate the removal of the watch stem, which in turn requires the disengagement of the setting lever. This delicate procedure demands meticulous attention to detail and a thorough understanding of the watch’s internal workings.
Safety Precautions
Before commencing any repair or manipulation of a watch movement, it is imperative to adhere to basic safety precautions:
- Always wear appropriate safety gear, such as gloves and safety glasses.
