Removing the Case Back and Accessing the Movement

Once you have secured the watch in a soft, stable position, the next step is to carefully remove the case back to expose the internal components. Watches generally have one of three types of case backs: screw-down, snap-on, or held by screws. Identifying the type is crucial to avoid damaging the watch during removal.

For a screw-down case back, use a case back wrench or a specialized case opener tool that fits the notches on the perimeter. Apply steady, controlled pressure to unscrew the case back counterclockwise. Avoid slipping, which can scratch or dent the metal. Snap-on backs require a thin, flat blade or a case knife to gently pry open the back by inserting the tool into the small gap or notch provided. For watches with screw-held backs, use a precision screwdriver to remove the screws evenly, storing them safely to prevent loss.

After removing the case back, you will see the watch movement protected by a dust cover or retaining ring in some models. Carefully lift any protective covers with a non-marring tool, and inspect the movement for screws or clamps holding it in place. These securing elements must be removed or loosened before the movement can be lifted out.

Detaching the Crown and Stem

Before fully removing the movement, detaching the crown and stem assembly is essential to prevent damage. This step varies depending on the watch mechanism, but common methods include pressing a small release button or loosening a set screw near the stem.

Locate the stem release mechanism, which is often a tiny lever or push-button near the movement’s edge. Using a fine-tipped tool or pin, gently press the release while simultaneously pulling the crown outward. In some watches, you may need to unscrew a collar or loosen a screw to free the stem.

Handle this step with care, as excessive force can bend or break delicate components. Once released, the crown and stem can be set aside separately.

Disassembling the Movement Components

With the movement free from the case and the crown removed, you can proceed to disassemble the internal components systematically. This process requires a clean, well-lit workspace, tweezers, screwdrivers of various sizes, and movement holders for stability.

Begin by removing the larger, more accessible parts such as the rotor (in automatic watches), bridges, and plates. Keep track of each screw and component, organizing them methodically to ensure accurate reassembly.

Pay special attention to the gear train, escapement, and balance wheel assemblies. These are intricate and delicate parts that require precise handling. Use magnification tools to avoid losing or damaging tiny components.

Below is a simplified overview of common movement parts and tips for disassembly:

Component Description Disassembly Tips
Rotor Oscillating weight for automatic winding Remove central screw carefully; note direction of rotation
Bridges and Plates Structural parts holding gears and components Loosen screws evenly; avoid applying pressure to gears underneath
Gear Train Series of wheels transmitting power Remove gears gently with tweezers; avoid bending teeth
Escapement Regulates gear train movement Handle with extreme care; avoid touching pallet stones
Balance Wheel Oscillates to control timing Remove balance cock screws carefully; do not disturb hairspring

Organizing and Documenting Parts for Reassembly

As you disassemble the watch, maintaining an organized approach is critical. Use compartmentalized trays or labeled containers to separate screws and components according to their position and function. Documenting each step with notes or photographs can greatly assist during reassembly, especially for complex movements.

Consider the following best practices:

  • Use a parts diagram or schematic as a reference.
  • Label parts with sticky notes or small containers.
  • Photograph each stage before and after removal.
  • Handle components with tweezers or gloves to avoid contamination.
  • Maintain a clean workspace free from dust and moisture.

This meticulous organization reduces the risk of losing parts and ensures accurate reinstallation of the movement and case components.
