Maintaining a high-quality watch requires more than just wearing it. Over time, dust, moisture, and normal wear can affect its performance. While some owners prefer to send their timepiece to a specialist, understanding the basic service routine empowers you to handle minor issues and extend the life of your investment. Below is a practical overview of the typical repair process for collectible watches.

Step 1: Opening the Case

The initial stage of any service involves removing the case back or bezel. This step demands precision and the right instruments. Using a case knife, a rubber ball, or a dedicated opener prevents scratches on the metal. Always work on a soft surface and note the orientation of each component. A careful approach here sets the tone for the entire repair.

Step 2: Cleaning the Internal Parts

Once the movement is exposed, every visible element must be cleaned. Accumulated dirt or old lubricant can hinder accuracy. Use a soft brush and a specialized cleaning solution designed for watch parts. Avoid aggressive solvents like acetone, as they can damage delicate pivots and jewel bearings. Rinse each part thoroughly and let them dry completely before reassembly.

Step 3: Replacing Worn Components

In many cases, you will discover a broken mainspring, a bent balance staff, or a loose screw. These parts are often available from watch supply shops or online marketplaces. When purchasing replacements, verify the exact reference number and quality. Genuine parts from the original manufacturer are ideal, but high-grade aftermarket options can also work well. Always choose a reputable vendor to avoid subpar materials.

Step 4: Lubricating the Movement

Proper lubrication reduces friction and prevents premature wear. Apply a small amount of high-quality watch oil to the key friction points: the balance wheel, the pallet fork, and the gear train jewels. Over-oiling is a common error that attracts dust and can stop the movement. Use a precision oiler and follow the manufacturer's recommendations for oil viscosity and quantity.

Step 5: Reassembling and Testing

The final step is putting everything back together in the reverse order of disassembly. Ensure each screw is tightened to the correct torque, and the hands align properly. After reassembly, wind the watch and check the timekeeping over 24 hours. If the watch gains or loses more than a few seconds per day, you may need to adjust the regulation lever. If you feel unsure, do not hesitate to consult a professional watchmaker.

While these steps cover the basics, complex repairs like replacing a chronograph module or fixing a date complication should be left to an expert. Attempting such work without experience can cause irreversible damage. Remember to store your watch in a dry, cool place and have it serviced every two to three years to maintain its performance.
