How do you use this "clock" if it has no contacts? Is it supposed to be part of a machine with some sort of exciter and detector?

It looks like a Rb gas filled cell removed from a Rb frequency standard. Interesting thingy to put on your shelf but of no practical use.

You mean they don't roll around at exact revolution?

It probably won't if your shelf is leveled
