A/h = Vibrations per hr./Oscilations per hr.

Hello there,

I have two questions that I hope you might have the answer to.

1) I still don't quite understand the difference between vibrations and oscilations per hour in mechanical watches, if there is any at all. A friend of mine explained to me that one oscilation equals to two vibrations. If it's true, then why do some watchmakers write 28'800 oscilations per hour, for example, and others 28'800 vibrations per hour when describing their watch movements? According to my friend, 28'800 vibrations per hour only equals to 14'400 oscilations. Is this correct?
2) Is a 28'800 more accurate than, let' say a 21'600 vibrations per hour movement?

Thank you,

Common man
