Watch movements, also known as a watch caliber, is an engine that behaves as a powerhouse for the watch. In mechanical watches, this comprises all elements necessary for time-telling, including the power source and all gears. Over time, watch movements can experience wear and tear, thereby affecting the accuracy of the timepiece. Regular monitoring of the wear and tear in watch movements is essential to extend their lifespan and make them more reliable. This process involves several steps, from simple visual examination to more meticulous watch testing procedures.
VISUAL INSPECTION
A visual inspection is the first step in monitoring wear and tear in your watch movement. This includes inspection of the watch case, watch face, and watch hands.
-
Watch Case: Look for scratches, dents, and corrosion on the watch case. Minor scratches are normal and can be buffed out easily. However, deeper dents and corrosion might require professional attention.
-
Watch Face: The watch dial or face should be pristine and free from scratches or dust. Fading or discoloring of numbers or markers may indicate excessive exposure to the sun or moisture.
-
Watch Hands: The watch hands should be moving freely without sticking at any point. If the hands are dragging or skipping, this may be a sign of a deeper issue in the watch mechanism.
While visual inspection can help identify external wear and tear, it is essential to look deeper into the watch’s movement for more serious issues such as gem wear, gear wear, and main spring wear.
INTERNAL INSPECTION
Removing the Watch Caseback: To examine the internal components of the watch, you’ll need to open the caseback. This should be done cautiously to prevent scratching or damaging the watch. If you’re unsure, it’s recommended to have this done by a professional watchmaker.
Once the caseback is removed, careful examination of the internal components can begin.
-
Gear Wear: Gears in the watch movement are one of the primary components that experience wear and tear due to continual use. Observe the teeth on each gear under a magnifying glass or loupe. Look for signs of sharpness or unevenness that indicate wear.
-
Jewel Wear: In watch movements, jewels serve as bearings for gears to reduce friction. Excessive wear in these jewels can impact the accuracy of the watch. Using a loupe, look for cracks, scratches, or chips in the jewels.
-
Mainspring Wear: The mainspring is the driving force behind a mechanical watch. Any signs of misshape, rust, or breakage can greatly affect the overall timekeeping ability of your watch.
Performing systematic visual and internal inspections will help you monitor wear and tear in your watch movement. However, to precisely assess the watch’s timekeeping accuracy, you might need to conduct further specialized tests.
