Whether your goal is repair, restoration, or just gaining insight into horology, this overview will prepare you to delve deeper into the art and science of watchmaking.

Removing the Watch Movement

Once the case back is removed, the next step is to carefully extract the watch movement. This delicate component houses the internal mechanisms responsible for timekeeping and requires cautious handling to avoid damage.

Begin by identifying the movement holder or retaining screws, which secure the movement within the case. Use a precision screwdriver to gently loosen these screws without stripping their heads. In some watches, a movement ring or spacer will need to be lifted out before the movement can be removed.

Before lifting the movement, ensure the crown and stem are disengaged. This is typically done by pressing a small lever or button near the stem inside the case, allowing the stem to slide out smoothly. Pulling the crown without disengaging the stem can damage both the crown and movement.

When lifting the movement, use movement tweezers or a movement holder tool to avoid direct contact with the delicate gears and balance wheel. Handling the movement by its edges minimizes the risk of disturbing the intricate components.

Disassembling the Dial and Hands

With the movement removed, the next phase involves detaching the dial and hands. This process requires precision and appropriate tools to prevent bending or scratching.

Start by removing the hands using a hand remover tool. Carefully position the tool beneath the hands, applying even upward pressure to lift them off their pinions. Avoid using excessive force, as this can damage the hands or the dial surface.

Once the hands are removed, the dial is typically secured to the movement by dial feet screws or clamps on the back of the movement. Locate these fasteners and gently loosen them. The dial should then lift away smoothly. If the dial is adhered with glue, use a plastic spatula to gently separate it without scratching.

Separating the Movement Components

After the dial is removed, the movement can be further disassembled into its constituent parts. This stage demands a clean workspace, proper lighting, and the right set of watchmaker tools such as screwdrivers, tweezers, and movement holders.

Key components to disassemble include:

  • Balance assembly: Contains the balance wheel, hairspring, and balance cock. It is crucial for regulating time.
  • Gear train: Includes the center wheel, third wheel, fourth wheel, and escape wheel, which transfer power through the movement.
  • Mainspring barrel: Houses the mainspring that stores energy.
  • Keyless works: Mechanism for setting time and winding, involving the winding stem, clutch, and setting lever.

Each part should be carefully removed, laid out in order, and documented if necessary to assist with reassembly.
