Removing the Watch Back and Inspecting Internal Components
To begin disassembling the internal workings of a wristwatch, the first step is to carefully remove the case back. Most watches have one of three types of case backs: snap-off, screw-down, or held in place by screws. Using the correct tool is essential to prevent damage.
- Snap-off case backs require a thin, flat tool such as a case knife. Gently insert the blade into the notch or gap and carefully pry the back off.
- Screw-down case backs need a specialized case wrench or adjustable case opener. Align the wrench teeth with the notches on the back, then turn counterclockwise to unscrew.
- Screw-held case backs require a precision screwdriver to remove the small screws evenly spaced around the perimeter.
Once the case back is removed, inspect the internal components visually to identify the movement type and any obvious damage or debris. The movement is the heart of the watch and can be mechanical (manual or automatic) or quartz.
Detaching the Movement from the Case
After exposing the movement, it is necessary to separate it from the watch case. This process varies depending on the watch design but generally involves the following steps:
- Remove the crown and stem: Locate the detent or release mechanism near the stem inside the movement. This may be a small push button or lever that allows the stem to slide out.
- Unscrew or unclip the movement holder: Some watches have a movement ring or holder that secures the movement inside the case. Remove any screws or clips holding it in place.
- Gently lift the movement: Use plastic tweezers or a movement holder to carefully lift the movement out of the case, avoiding direct contact with delicate components.
Handle the movement with care to prevent damage, and avoid touching the dial or hands directly as oils from fingers can cause staining.
Removing the Hands and Dial
Once the movement is free from the case, the next step is to remove the hands and dial to access the underlying components.
- Removing the hands: Use a hand remover tool that fits under the hands without touching the dial. Position the tool’s forked ends beneath the hands and gently pry them upwards. Remove the hands in the following order:
- Seconds hand
- Minute hand
- Hour hand
- Removing the dial: The dial is typically secured by small dial feet screws on the side of the movement or by clips under the dial. Loosen these screws or clips carefully. Once freed, lift the dial straight up to avoid damaging the feet or dial surface.
Understanding the Movement Components
Familiarity with the key components inside a watch movement is crucial for effective disassembly and repair. Below is a table summarizing the primary parts and their functions:
| Component | Description | Function |
|---|---|---|
| Mainspring | A coiled spring inside the barrel | Stores and releases energy to power the watch |
| Gear Train | Series of gears connecting mainspring to escapement | Transmits energy and controls movement of hands |
| Escapement | Includes escape wheel and pallet fork | Regulates energy release to maintain accurate time |
| Balance Wheel | Oscillating wheel with hairspring | Controls timing through regular oscillations |
| Dial Train | Intermediate gears attached to hands | Drives motion of hour, minute, and second hands |
Each part requires precise handling and proper tools for removal, adjustment, or replacement.
Disassembling the Movement
When ready to further disassemble the movement, proceed methodically and keep parts organized. Follow these guidelines:
- Work on a clean, well-lit surface with a soft pad.
- Use appropriate screwdrivers and tweezers designed for watchmaking.
- Remove screws in a logical order, noting their location and size.
- Avoid forcing parts; components should come apart with gentle coaxing.
- Place small components in labeled containers or trays to prevent loss.
Start by removing the balance wheel assembly, then proceed to unscrew and remove the pallet fork, escape wheel, and gear train components. This approach prevents damage to delicate parts and maintains the integrity of the movement for reassembly or repair.
