Why do mechanical watches need servicing and oiling?

　　Why do mechanical watches need servicing and oiling? Many friends who are not familiar with watches may not know what watch oiling means, nor what purpose it serves. To answer your questions, Xiaoya will explain the reasons for oiling a mechanical watch below.

　　Reasons for oiling a mechanical watch

　　A mechanical watch is driven by a mainspring that powers many interlocking gears to run. Because metal parts are in contact and wear against each other over long periods, and to ensure the stable operation of the gear bearings, lubricating oil must be used. However, over time, the lubricating oil will dry up and deteriorate, and even oil sludge can cause damage to the metal parts of the movement.

　　During the use of a watch, the lubricating oil applied to the parts will gradually evaporate and dry up over time; the mutual friction of the gears will produce fine metal debris, increasing rotational resistance; dust, fibres, etc., will continuously penetrate through the gaps in the case, becoming movement grime. Therefore, after a certain period of use, the watch movement parts need to be disassembled, cleaned, and re-lubricated.

　　Potential issues before movement oiling

　　1. The lubricating oil on the movement parts has dried up or become sticky. This increases the resistance to the operation of the movement parts, causing the movement to keep inaccurate time;

　　2. Too much lubricating oil in the movement will cause the oil to overflow, contaminating the movement parts, especially the escapement regulating mechanism and the balance wheel, thereby affecting the timekeeping of the movement;

　　3. Foreign objects in the movement, such as dust particles, metal debris, fibres, fingerprints, and sweat stains, which can affect the lifespan and timekeeping stability of the movement;

　　4. Rust spots on the movement. Moisture or water vapour previously corroding the watch will cause rust spots and metal fatigue on metal parts. If not cleaned in time, it will become increasingly serious, posing a fatal threat to the metal parts of the movement.

　　How often does a mechanical watch need oiling?

　　For standard watches, 3-5 years is acceptable. Whether it should be 3 years or 5 years can be determined as follows: within 3 years, leave it alone; at the 3-year mark, pay attention to the daily rate variance. It is best to record the daily variance continuously for a week, calculate the average, and log it down. For example, if it gains an average of 12 seconds per day, once the variance shifts to gaining an average of about 7 seconds per day—meaning it has slowed down by an average of 5 seconds—it is time to send it for cleaning and oiling.
