Opening a watch can be a daunting task, especially if you’ve never done it before. But with a little patience and the right tools, it’s actually quite simple. In this article, we’ll walk you through the steps on how to open a watch safely and without damaging the watch. We’ll also provide some tips on how to choose the right tools for the job.
Before you start, it’s important to gather the right tools. You’ll need a watchmaker’s screwdriver, a case knife, and a pair of tweezers. You can purchase these tools online or at a local hardware store. Once you have your tools, you’re ready to start opening the watch.
The first step is to remove the watchband. This is usually done by unscrewing the screws that hold the watchband in place. Once the watchband is removed, you’ll need to use the case knife to pry open the case back. Be careful not to damage the case back or the watch movement. Once the case back is open, you’ll have access to the watch movement. You can now perform any repairs or maintenance that is needed.
Identifying Watch Components
Case
The case, or housing, is the primary structure that holds all the watch’s components. It typically consists of:
- Bezel: The outer rim surrounding the crystal, often engraved with markings or a tachymeter scale.
- Crystal: The transparent cover that protects the dial and hands. It can be made of various materials, such as sapphire, mineral, or acrylic.
- Caseback: The metal plate at the back of the case, which seals the watch and protects the movement.
- Lugs: Small protrusions on the case where the watchband is attached.
Dial
The dial is the face of the watch that displays the time and other information. It typically includes:
- Hour Markers: Numbers or dashes that indicate the hours.
- Minute Markers: Small marks or lines that divide the hours into minutes.
- Hands: The rotating pointers that indicate the time.
- Subdials: Small dials within the main dial that display additional functions, such as a chronograph or calendar.
Movement
The movement is the mechanism that powers the watch and tells time. There are two main types:
- Mechanical Movement: Powered by a spring that is wound manually or automatically. It consists of gears, springs, and balance wheel.
- Quartz Movement: Powered by a battery that generates electrical pulses to move the hands. It is more precise and reliable than a mechanical movement.
| Movement Type | Advantages | Disadvantages |
|---|---|---|
| Mechanical | Prestige, craftsmanship, artistic value | Less precise, requires regular maintenance |
| Quartz | Accuracy, reliability, low maintenance | Less appealing to watch enthusiasts |
Preparing the Watch
Before attempting to open the watch, it is essential to prepare the necessary tools and materials.
Tools and Materials
| Tool | Purpose |
|---|---|
| Watchmaker’s screwdriver | To remove small screws |

Once the necessary tools and materials are gathered, it is important to ensure that the workspace is clean, well-lit, and free from debris.
Disassembling the Band
To begin, it is necessary to disassemble the watch band. Different types of watch bands require different methods of removal. Some bands are held together by pins that can be pushed out using a watchmaker’s screwdriver, while others use screws or links that need to be unscrewed or removed manually.
Removing the Caseback
The caseback is the part of the watch that covers the movement. In order to access the movement, you will need to remove the caseback. There are a few different ways to do this, but the most common method is to use a caseback opener.
A caseback opener is a tool that is specifically designed to remove watch casebacks. There are a variety of different caseback openers available, so you will need to choose one that is compatible with your watch.
Once you have a caseback opener, you can follow these steps to remove the caseback:
1. Place the watch in the caseback opener.
2. Adjust the caseback opener so that it is properly aligned with the caseback.
3. Apply pressure to the caseback opener.
4. Turn the caseback opener counterclockwise until the caseback is loose.
5. Remove the caseback from the watch.
If you are not comfortable removing the caseback yourself, you can take your watch to a jeweler or watchmaker and have them do it for you.
Accessing the Movement
Now that the back of the watch is open, you’ll have access to the movement inside. The movement is the intricate mechanism that powers the watch and keeps track of time. It’s usually made up of a series of gears, springs, and other delicate components.
When accessing the movement, it’s crucial to be careful not to damage any of the components. Use a soft-bristled brush or a blower to gently remove any dust or debris. Avoid touching the movement directly with your fingers, as this can transfer oils and dirt.
If you need to remove the movement from the case for any reason, do so carefully. Use a pair of needle-nose pliers to gently lift the movement out of the case. Be sure to support the movement from the bottom so that it doesn’t fall and damage.
Once the movement is removed, you can inspect it for any damage or wear. If you notice any problems, it’s best to take the watch to a qualified watchmaker for repair.
Additional Tips for Accessing the Movement
- Use a watchmaker’s loupe to get a closer look at the movement.
- If you’re not comfortable working on the movement yourself, take the watch to a qualified watchmaker.
- Be patient and take your time. Accessing the movement can be a delicate process, so don’t rush it.
Note: The specific steps for accessing the movement may vary depending on the type of watch. Consult the watch’s manual or a qualified watchmaker for specific instructions.
Removing the Battery (if applicable)
If your watch requires a battery, you will need to remove it before you can open the case. To do this, you will need a small screwdriver or other pointed object.
1. Locate the battery compartment on the back of the watch. It is usually held in place by a small screw.
2. Use the screwdriver to loosen the screw and remove the battery compartment.
3. Carefully remove the battery from the compartment. Be careful not to damage the battery or the watch.
4. Dispose of the old battery properly.

Reassembly of the Movement
Once the movement has been cleaned and lubricated, it is time to reassemble it. This is a delicate process that requires patience and precision. If you have no idea about the watch movement’s reassembly, I suggest doing some research initially. The below guideline might also seem confusing for a person with zero knowledge about a watch. It is highly recommended to seek help from an expert if you have never opened a mechanical watch before.
Begin by laying out all of the movement’s parts on a clean surface. Use a magnifying glass to inspect each part for any damage. If any parts are damaged, they will need to be replaced before you can reassemble the movement.
Once you have inspected all of the parts, start by reassembling the mainspring barrel. The mainspring barrel is a small, cylindrical part that stores the mainspring. The mainspring is a coiled metal spring that provides the power to drive the watch’s movement.
To reassemble the mainspring barrel, first, insert the mainspring into the barrel. Then, place the barrel cover on top of the mainspring and secure it in place with a screw.
Next, reassemble the gear train. The gear train is a series of gears that transfer power from the mainspring barrel to the balance wheel. To reassemble the gear train, start by placing the center wheel on the mainspring barrel. Then, add the second wheel, followed by the third wheel, and finally, the escape wheel.
Once you have reassembled the gear train, reattach the balance wheel. The balance wheel is a small, weighted wheel that regulates the speed of the movement.
To reattach the balance wheel, first, place the balance spring on the balance wheel. Then, place the balance wheel on the balance cock and secure it in place with a screw.
With the movement reassembled, it is time to test it. Wind the watch and see if it runs. If the watch does not run, check to make sure that all of the parts are assembled correctly. Once the watch is running, regulate it so that it keeps accurate time.
### Step 8: Regulating the Watch
Once the movement is reassembled, it needs to be regulated so that it keeps accurate time. This is done by adjusting the length of the balance spring. If the balance spring is too long, the watch will run slow. If the balance spring is too short, the watch will run fast.
To regulate the watch, use a pair of tweezers to gently bend the balance spring. Bend the spring slightly in one direction and then the other until the watch is keeping accurate time.
| Too long | Too short |
|---|---|
| Watch runs slow | Watch runs fast |
| Bend spring shorter | Bend spring longer |
Installing the New Battery (if applicable)
To install a new battery in your watch, you will need the following:
