Removing the Watch Case Back

The first critical step in disassembling a wrist watch is to remove the case back, which protects the watch movement and internal components. The method for opening the case back depends on the watch’s design, and using the correct tools will prevent damage.

There are generally three types of case backs:

  • Snap-off case backs: These have a small lip or notch where you can insert a case knife or a flat tool to pry the back off.
  • Screw-down case backs: These have grooves or indentations around the edge and require a case back wrench or a specialized tool to unscrew.
  • Screw-in case backs with screws: These are held by small screws around the perimeter and require a precision screwdriver.

When attempting to open the case back, it is essential to work on a clean, stable surface with adequate lighting. Protect the watch crystal and case by using a soft cloth or pad underneath.

Use the following tips for safe removal:

  • Identify the case back type before attempting removal.
  • For snap-off backs, gently insert the blade under the notch and carefully pry open.
  • For screw-down backs, align the case back wrench with the grooves and turn counterclockwise.
  • For screw-in backs, use the correct size screwdriver to remove each screw evenly.
  • Avoid excessive force to prevent deformation or scratching.

Extracting the Movement from the Case

Once the case back is removed, the next step is to carefully extract the movement, which houses the intricate mechanism powering the watch.

Before proceeding, note:

  • The movement is delicate and sensitive to dust, moisture, and static.
  • Always handle the movement with clean, dry hands or use antistatic gloves.
  • Use plastic or wooden tools where possible to avoid scratches.

Steps to remove the movement:

  • Locate and remove the movement retaining screws or clamps holding it in place.
  • Gently lift the crown and stem out, usually by pressing a small release lever or button near the stem tube.
  • Carefully lift the movement from the case using movement holders or tweezers designed for watchmaking.
  • Avoid touching the dial or hands directly to prevent damage.

Disassembling the Dial and Hands

With the movement removed, disassembling the dial and hands requires precision and care.

Start by:

  • Removing the hands using hand levers or hand removers that fit around the base of the hands without bending them.
  • Take note of the order and position of the hands (hour, minute, and second) to reassemble correctly.
  • Avoid applying excessive pressure to prevent bending or breaking the hands.

Next, remove the dial:

  • The dial is typically secured by small screws or clips on the movement’s side.
  • Loosen these screws or carefully release the clips to free the dial.
  • Lift the dial gently to avoid damaging the feet or dial surface.

Organizing and Documenting Components

During disassembly, maintaining an organized workspace and documenting the process is crucial for successful reassembly.

Helpful practices include:

  • Using labeled trays or containers for screws, springs, and small parts.
  • Taking photos at each disassembly stage for reference.
  • Keeping a written log or diagram of part positions and orientations.
