Emperor made the case and imported the movement. You have not
provided enolugh information to know what's in there.
Call another local clocksmith and ask him his differnece on a
warrantied ovrhaul vs a new movement, if in fact they are available.
Please keep in mind that anything made after 1965 to present will
be of relatively middle of the road quality and last somewhere between
15 to 25 years even with routine maintence.
In other words, go with the cheapest option because the clock has no
antiquite value and your attachment for it gives it it's vlaue.
