How Do I Repair a Slow Running Mechanical Watch?
A slow-running mechanical watch is a common problem that can be frustrating to deal with. However, with the right tools and knowledge, you can easily repair the watch yourself.
Step 1: Check the Power Reserve
The first step is to check the power reserve of the watch. This is the amount of time the watch can run without being wound. If the power reserve is low, the watch will run slowly or stop altogether. To check the power reserve, simply wind the watch fully and then observe how long it runs.
Step 2: Clean the Mainspring
If the power reserve is adequate, the next step is to clean the mainspring. The mainspring is a coiled metal spring that provides the power to the watch. Over time, the mainspring can become dirty or clogged, which can cause the watch to run slowly. To clean the mainspring, remove the back of the watch and locate the mainspring. Use a cotton swab dipped in alcohol to clean the mainspring and any other visible dirt.
Step 3: Lubricate the Movement
Once the mainspring is clean, you need to lubricate the movement. The movement is the part of the watch that contains all the gears and springs. Lubrication is essential for keeping the movement running smoothly and preventing wear and tear. To lubricate the movement, use a small amount of watch oil on the gears and other moving parts.
Step 4: Regulate the Watch
The final step is to regulate the watch. This involves adjusting the speed of the watch so that it keeps accurate time. To regulate the watch, you will need a timing machine or a digital oscilloscope. Once you have these tools, follow the instructions in your watch manual to regulate the watch.
