Once the case back opener is in place, you can turn it to remove the case back. Be careful not to turn the case back opener too far, as this can damage the case back or the movement.

Identifying the Movement

The movement is the heart of a watch, and it determines how the watch keeps time. There are two main types of watch movements: mechanical and quartz.

Mechanical movements use a series of gears and springs to power the watch. These movements are generally more expensive than quartz movements, but they are also more accurate and durable.

Quartz movements use a battery to power a quartz crystal. The crystal vibrates at a very precise frequency, which is used to keep time. Quartz movements are less expensive than mechanical movements, but they are also less accurate and durable.

To identify the movement of a watch, you will need to open the watch case. This can be done with a special watchmaker’s tool called a case opener. Once the case is open, you will be able to see the movement inside.

Identifying the Movement Type

The movement type can be identified by looking at the balance wheel. The balance wheel is a small, round wheel that is attached to the mainspring. In a mechanical movement, the balance wheel will have a hairspring attached to it. In a quartz movement, the balance wheel will not have a hairspring.

Identifying the Movement Caliber

The movement caliber is a number that identifies the specific model of the movement. The caliber number can be found on the movement itself. It is usually engraved on the main plate.

| Manufacturer | Caliber | Movement Type |
|—|—|—|
| Rolex | 3135 | Mechanical |
| Omega | 8500 | Co-Axial |
| Seiko | 7S26 | Mechanical |
| Citizen | Miyota 8215 | Quartz |
| Casio | Module 3229 | Quartz |

Accessing the Battery

Accessing the battery on a typical wristwatch requires carefully prying open the back cover or case. Here is a detailed step-by-step guide to opening a watch to access the battery:

1. Gather Tools:

You will need a small screwdriver or a watch repair kit with a suitable tool for opening the watch case.

2. Locate the Caseback Opening:

Examine the back of the watch and identify the caseback opening. It is usually a circular or rectangular recess with a small notch or groove.

3. Insert Tool and Pry Open:

Insert the screwdriver’s tip or the watch repair tool into the notch or groove and gently pry open the caseback. If the caseback is tightly sealed, apply gentle force and avoid damaging the watch or the tool.

4. Replace the Battery

The battery is typically held in place by a metal clip or bracket. Carefully remove the old battery and insert the new one, ensuring that its positive (+) and negative (-) terminals match the orientation of the old battery. Some watches may have a small metal tab that secures the battery; gently pry it up and replace it after inserting the new battery.

Continue applying pressure and rotating the hand remover until you feel the hand loosen and lift away from the cannon pinion. Do not pull or pry at the hand, as this could damage its delicate components. Gently slide the hand off the pinion and place it in a safe location for later reassembly.

Dismantling the Dial

The dial is the front face of the watch that displays the time. To dismantle the dial, you will need to remove the hands, the crystal, and the dial itself.

Removing the Hands

The hands are held in place by friction. To remove them, you will need to use a watchmaker’s tool called a hand remover. This tool is a small, forked tool that fits under the hand and allows you to gently pry it off.

Removing the Crystal

The crystal is the clear cover that protects the dial. To remove the crystal, you will need to use a watchmaker’s tool called a crystal press. This tool is a small, hand-held press that allows you to gently press the crystal out of the case.

Removing the Dial

The dial is held in place by a series of screws. To remove the dial, you will need to use a watchmaker’s screwdriver. Be careful not to overtighten the screws when you put the dial back in place.

Dial Feet

The dial is typically held in place by four or more dial feet. These feet are small, metal tabs that are soldered to the dial. When the dial is installed in the watch case, the dial feet fit into corresponding holes in the case. The dial is then secured in place by screws that pass through the dial feet and into the case.

Dial Spacers

In some cases, dial spacers may be used to adjust the height of the dial in the watch case. Dial spacers are thin, metal washers that are placed between the dial and the movement. By adding or removing dial spacers, the watchmaker can ensure that the dial is properly aligned and that the hands clear the crystal.

Dial Gaskets

A dial gasket is a thin, rubber gasket that is placed between the dial and the watch case. The dial gasket helps to seal the watch case and prevent moisture from entering the movement. When replacing the dial, it is important to use a new dial gasket to ensure a proper seal.
