Frequently asked questions about Longines watch servicing

　　During the routine maintenance of Longines watches, you are bound to encounter various issues. Below is a collection of common troubleshooting tips for Longines watch care compiled by Xiaoya for your reference.

　　Frequently asked questions about Longines watch maintenance

　　I. Factors affecting movement operation

　　1 The case back presses too tightly against the bridge or casing ring, affecting the wheel clearance. Examples include: missing sealing gasket, jewel screw protruding too much, a thin case back being dented or warped, or the case and casing ring being too tight so that forceful pressing distorts the bridge.

　　2 Mutual friction between the dial and hands, or friction involving internal movement components. Examples include: hands rubbing against each other; second hand rubbing against the crystal (watch glass); dial centre hole rubbing the hour tube or hour wheel; dial centre hole and hour wheel clearance being too small; uneven dial pressing against the minute-work wheel or other parts.

　　3 Friction between the casing ring and internal movement components. Examples include: casing ring rubbing against the barrel teeth or balance wheel.

　　II. Causes affecting winding and time-setting

　　1 The case back, once screwed down, presses against the winding stem or crown thread tube. Examples include: missing sealing gasket; after fitting a longer or medium replacement crown, a thicker thread tube extends into the case.

　　2 Following the replacement of the case or dial, the height alignment between the movement stem hole and the crown tube hole is incorrect.

　　3 The rotation of the case back causes the casing ring to jam the winding stem, preventing the stem from being pulled out into the time-setting position.

　　4 The friction from the rotating case back drives the internal movement, causing the winding stem to bind. For the last two faults, screwing down the case back and then turning it back slightly (by about 2-3 degrees) will resolve the issue.

　　III. Causes of changes in balance wheel behaviour

　　This occurs because the balance wheel rubs against the centre wheel pinion, bridge, or the outer curb of the regulator. These issues may arise if the balance upper and lower jewels are not fitted flat, the balance pivot tips are severely worn, or the balance pivot position is inaccurate after machining. Severe cases of this fault will cause the watch to stop; if the balance wheel itself is uneven, it will significantly reduce the amplitude, and a large mainspring torque can also cause frictional stopping. If the centre wheel pinion is not flat, it will affect the amplitude and cause periodic friction. In certain models, the barrel teeth are positioned close to the balance wheel, and issues such as barrel arbor hole wear can cause the barrel teeth to rub against the balance wheel. Sometimes balance screws loosen or washers are too large and thick, rubbing against surrounding bridges or components, or a thick pallet bridge screw rubs against the balance wheel; in such cases, friction or knocking sounds will be heard.
