As you prepare to delve deeper into the step-by-step process, you’ll discover the importance of proper tools, a steady hand, and a respectful attitude toward these miniature mechanical marvel

Removing the Movement from the Case

Once the back cover of the pocket watch is open, the next step is to carefully extract the movement, which is the intricate mechanism inside the watch. This process requires precision and a steady hand, as the movement is delicate and can be easily damaged.

Begin by locating the movement retaining screws or clamps. These small screws or levers secure the movement within the case and must be loosened or disengaged before the movement can be removed. Use a precision screwdriver suited for watchmaking to avoid stripping the screws.

After loosening the screws, gently lift the movement out of the case. It is advisable to use non-magnetic tweezers to prevent any magnetic interference with the watch components. Support the movement firmly but gently, avoiding pressure on the balance wheel or other fragile parts.

If the watch has a dust cover over the movement, carefully remove it by releasing any clips or screws holding it in place. Document each step with notes or photographs to assist with reassembly later.

Disassembling the Dial and Hands

With the movement free from the case, the next task is to remove the dial and hands. This step exposes the internal gear train and other components, allowing for further inspection or repair.

The hands are typically pressed onto the central pinion. Use a hand remover tool designed specifically for watches to avoid bending or damaging the hands. Apply even pressure and lift the hands straight off, starting with the seconds hand, then the minute and hour hands.

Once the hands are removed, detach the dial. The dial is commonly secured to the movement with small screws or dial feet that fit into slots on the movement plate. Loosen these screws or gently release the dial feet, taking care not to chip or scratch the dial surface.

Place the dial and hands in a safe, clean container to prevent loss or damage.

Systematic Removal of Internal Components

With the dial removed, the heart of the pocket watch is accessible. Disassembling the movement further requires methodical work, as many tiny parts and springs are under tension.

Start by removing the winding mechanism, which often includes the crown wheel and ratchet wheel. These components are usually secured with small screws.

Next, dismantle the gear train, which consists of the center wheel, third wheel, fourth wheel, and escape wheel. Each wheel should be carefully lifted out after loosening its corresponding bridge or cock screws.

The balance assembly, including the balance wheel and hairspring, must be handled with extreme care. Release the balance cock screw and gently lift the assembly, ensuring the hairspring is not bent or deformed.

Use a parts tray with compartments to organize screws and components systematically.
