GUEST: My mother picked it up in-in probably the late '40s at an antique store.

APPRAISER: It’s called an annular clock and it's French.

And instead of a traditional clock with two hands, a minute hand and an hour hand telling the time, this enameled band spins with the arrow being the indicator in the front.

This is the Three Graces clock.

These are Zeus's daughters and they represent all the positive aspects of life in society.

They're a bronze figure that have been patinated with a chemical that makes them this black color.

It has these three tapered feet that are brass and they're really wonderfully done.

I love all these ormolu open fret bronze castings that are gilded just over the top.

You have this beaded border on this triangular marble base and you have these wonderful garlands.

It just presents itself really well.

You come to the top, you have the spear and then you have these wonderful ormolu mounts and then the putti at the top sitting on a cloud.

When do you think this clock was made?

GUEST: I think inside it says 1807.

APPRAISER: That has a serial number, 1807 on it.

GUEST: Oh.

(chuckles) APPRAISER: It's actually later than that.

It's, uh, it's a clock that was made circa 1890.

This top comes off, but as you know, it was pretty hard to take off.

And inside is a beautiful eight-day French movement.

It's also stamped on the top plate "J. Lefebvre Fils" which is sons, excuse my pronunciation of the French language.

It's the best I can do-- and it was made in Paris.

So this is a clock copied from the original that was produced by François Vion circa 1765-- but this is a later copy.

These were a very popular clock.

A lot of Parisians made the cases and a lot of French clock makers would put their movements inside of these cases.

And you can see the bottom half of the sphere has a little deterioration.

This is the original paint at the bottom.

And this has been highlighted at some time.

And it's also missing a torch, but honestly, really not a big deal at all.

In this as-is condition, in a retail setting, this clock would sell for around $15,000.

GUEST: Wow.

(chuckles) That's amazing to me.
