Are you referring to Atmos clocks?

OP might mean Hairspring?

Ah, silly me.

It's just that I serviced an Atmos last year and the movement is so delicate and is designed to run without oil and is powered by atmospheric pressure and temperature. The reason I had to service it was someone had oiled it and it stopped.

Hello if it is a hairspring you mean, then this should have no oil on it at all, only in the pivots and then only a tiny amount, if you take a photo of the offending piece this always helps to decipher whats going on.
