Have you ever wonder why can't you just use one type of general-purpose oil for the entire watch movement?

Why can't you just use one type of general-purpose oil...
Different parts of the movement experience different forces. High-speed, low-torque parts (like the balance pivots) require very thin, light oil so they don't drag. Low-speed, high-torque parts (like the mainspring barrel arbor) require heavy oil or grease to withstand the heavy friction.
