Disassembling the Watch

Before beginning repairs, carefully disassemble the watch to access the internal components. Use a clean, well-lit workspace and appropriate tools such as a case opener, screwdrivers, tweezers, and a loupe. Start by removing the watch back, which may be a snap-off, screw-down, or held by screws. Exercise caution to avoid scratching or damaging the case.

Once the back is removed, gently extract the movement from the case. Note the position of the crown and stem as you remove them, since these parts are delicate and essential for time-setting functions. Keep all screws and small parts organized, preferably in a parts tray or labeled containers, to avoid losing any components.

When removing the dial and hands, use hand levers designed for watchmaking. Carefully lift the hands off the dial without bending or scratching them. The dial itself is often secured by small screws or clips; loosen these and lift the dial gently.

Cleaning and Inspecting Components

After disassembly, each component should be thoroughly cleaned and inspected. Dust, dirt, and old lubricants can impair the watch’s function. Use specialized cleaning solutions and ultrasonic cleaners for metal parts, but avoid immersing delicate parts such as the balance wheel or hairspring in liquid.

Inspection involves checking for wear, damage, or corrosion. Look for:

  • Worn teeth on gears or pinions
  • Broken or bent hairspring
  • Cracked or chipped jewels
  • Rust or discoloration on metal parts
  • Loose or missing screws

Replace any damaged components with genuine or compatible parts. Magnification tools are essential for detecting fine defects that could affect accuracy.

Lubrication Techniques

Proper lubrication minimizes friction and wear, ensuring smooth operation. Use watchmaker’s oils and greases sparingly, applying them only to designated points such as pivots, escape wheels, and gear teeth.

Key points for effective lubrication:

  • Use the correct grade of oil depending on the component (light oils for fast-moving parts, heavier grease for slower or high-load areas).
  • Avoid over-oiling, which can attract dust and cause gumming.
  • Apply oil with an oiler tool or fine brush, targeting the jewel holes and contact surfaces precisely.
  • Regularly clean the oiler tip to prevent contamination.

Below is a table summarizing common lubrication points and recommended oils:

Reassembling the Watch

Careful reassembly is crucial for restoring the watch’s function. Follow the reverse order of disassembly, ensuring each part is correctly seated and aligned. Use tweezers to position tiny components and avoid touching surfaces with bare fingers to prevent oil contamination.

When reinstalling the dial and hands, make sure the hands do not interfere with each other or the dial. Check that the crown and stem engage smoothly with the movement’s setting mechanism. After placing the movement back into the case, secure the case back firmly to maintain water resistance if applicable.

Testing and Calibration

Once reassembled, test the watch for accuracy and functionality. Wind the watch fully and observe the movement for smooth operation. Use a timing machine to measure rate, amplitude, and beat error. Adjust the regulator or balance wheel screws to correct timing deviations.

Other tests include:

  • Checking date and time-setting mechanisms
  • Assessing power reserve duration
  • Ensuring the watch starts and stops correctly if it has a chronograph function
  • Verifying water resistance with appropriate equipment if the watch is rated for it

Proper calibration may require multiple adjustments and retesting to achieve optimal performance.

Common Issues and Troubleshooting

Even with careful repair, some problems may persist or arise. Address these common issues as follows:

  • Watch stops intermittently: Check for dirt or dried lubricant in the gear train; clean and relubricate as needed.
  • Hands sticking or misaligned: Ensure hands are pressed correctly onto their posts and are not bent or rubbing against the dial or each other.
  • Crown difficult to turn or pull out: Inspect the winding stem and crown tube for damage or dirt; lubricate or replace parts if necessary.
  • Inaccurate timekeeping: Reassess the balance wheel and hairspring for damage or magnetization; demagnetize and regulate as required.

By methodically addressing these issues, you can restore the watch to reliable operation.

Understanding the Components of a Watch

Before initiating any repair work, it is essential to have a clear understanding of the basic components that make up a watch. Most watches consist of the following parts:

  • Case: The outer shell that houses the watch movement and protects it from dust and moisture.
  • Crystal: The transparent cover over the dial, often made of glass, acrylic, or sapphire.
  • Dial: The face of the watch that displays the time, usually with hour markers and hands.
  • Hands: The indicators for hours, minutes, and seconds that move over the dial.
