Removing the Case Back and Accessing the Movement

Once the watch strap or bracelet has been removed, the next step is to open the case back. There are several types of case backs, each requiring a specific approach to avoid damage.

  • Snap-off case back: These have a small lip or notch for a case knife to pry open the back gently.
  • Screw-down case back: These require a case back wrench or a dedicated tool with adjustable pins to unscrew the back.
  • Screw-secured case back: Tiny screws secure these backs, which can be removed using an appropriately sized screwdriver.

When working with screw-down or screw-secured backs, ensure the tool fits precisely to prevent slipping or scratching. Work on a clean, flat surface with good lighting to facilitate careful handling.

After opening the case back, you will typically see a dust cover or protective ring. This must be removed carefully to expose the watch movement. Use plastic tweezers or a wooden stick to avoid touching the movement with your fingers, which could introduce oils or dirt.

Removing the Crown and Stem

The crown and stem assembly is critical for setting the time and winding the watch. Removing it properly is essential to prevent damage to the movement.

Most movements have a small release mechanism to detach the stem:

  • Locate the stem release lever or button near the stem tube inside the movement.
  • Using a fine, non-magnetic screwdriver or pegwood, gently press the release while carefully pulling the crown and stem outwards.
  • Avoid forcing the stem out; if resistance is felt, double-check the release point.

If the release mechanism is not apparent, consult the movement’s technical manual or a reliable database to identify the correct procedure.

Disassembling the Movement Components

Disassembling the movement requires precision and patience. Follow these general guidelines:

  • Work systematically, removing components in the order they appear.
  • Use a movement holder to secure the movement firmly but gently.
  • Use a magnifying loupe to inspect screws and components closely.
  • Store small parts in labeled containers or a parts tray with compartments to avoid mixing.

Typical movement components to remove include:

  • Balance wheel and balance cock
  • Pallet fork and bridge
  • Gear train wheels (center wheel, third wheel, fourth wheel, escape wheel)
  • Mainspring barrel and barrel bridge

Handle each part delicately, especially the balance wheel and hairspring, as they are very sensitive to deformation.
