1, when the watch movement is refueled, the spring ring is injected with clock oil, generally injected three drops, the upper pull shaft of the needle system, the needle wheel shaft, the small steel wheel shaft sleeve, the cross-wheel shaft, the clutch wheel teeth and the vertical wheel helical teeth can be injected with clock oil, such as Rolex each part can be injected with two drops of the pen.

2, between the shaft and the bar box, the shaft and the upper and lower splints, the upper and lower shaft of the center wheel, the wheel, the second wheel, the escapement wheel, the small central shaft of the center wheel, the impact surface of the fork tile, the upper and lower drilling of the pendulum shaft, etc., should be filled with oil, and a drop can be injected with a fine oil pen. However, there are still some parts of the watch movement that do not need or even avoid contact with the part, the disk nail, escapement fork, fork eye, these parts can not be injected with oil, these parts will increase the resistance of the operation after oil injection, so that it is not sensitive, reducing the momentum.

3, to avoid contact with the oil part of the spring, spring and oil contact will produce adhesion effect, will affect the balance wheel rotation amplitude and vibration frequency. A small amount of silicone oil should be injected into the handle head. It is strictly prohibited to inject lubricating oil, which will cause deterioration of the waterproof liner and the handle head.
