Keystone Clock Oil BottleThis Keystone Clock Oil Bottle is a great mid grade oil for mechanical clock units. This bottle will last for a very long time unless clock repair is your full time job. Apply the smallest drop to anything that spins within something else. For example the pivot that spins in the outer clock plates.
It would be hard to "over oil" a clock, but it will create a mess down the road. So the idea of less is more is quite applicable. When using a small drop, it will be easy to see it going into the arbor. There should never be a pool of oil or oil dripping down the movement. This is a 2 oz glass bottle of oil.
