Precision Needle Pen Clock Oiler that contains quality semi-synthetic general purpose oil. The applicator makes it easy to reach pivot holes as well as other spots. The long needle enables you to get into the hardest to reach areas in the middle of the movement.
Once the pen is empty, simply unscrew the top and fill it back up for non-stop easy use. Stop the onset of corrosion by putting the smallest drop wherever one thing rubs another in the movement. If it slides, grease it. If it spins, oil it.
