GUEST: It's my, uh, wife's grandparents' clock purchased by her grandfather.

My, uh, wife remembers it always being in the house, uh, growing up.

I know it's J.E.

Caldwell.

I don't know if he was the manufacturer or if he was more of a, uh, importer and reseller.

APPRAISER: Yeah.

Well, he was actually a retailer.

And his retail shop in Philadelphia became the biggest in the city.

They became very well-known for selling clocks of the highest grade.

So the case form is called a bracket clock.

It's a form that was made for... a couple of centuries.

This is the Victorian example, meaning that it was probably made about 1880 or so.

It represents the best of its category in terms of having a very solidly built, robust mechanism with fusee compensation.

It has a, a... a number of features which are displayed here on the dial.

Here you have a shut-off for the strike portion of the clock.

You can turn this clock silent so it just ticks, or you can turn it on and it'll do the quarter-hour striking as well as the hour striking.

And then the center dial here, actually is for rating the clock.

So, uh, temperature is a variant that.. affects clocks greatly.

Warm rooms, they slow down.

Cold rooms, they speed up.

Instead of having to turn this clock around and actually adjust the pendulum, you can do some fine adjusting from the front of the dial.

APPRAISER: The case is mahogany, the finest wood.

And you can see that it is wonderfully adorned with, uh, all kinds of brass appointments, full Corinthian capitals on the... fluted columns, chased feet with roses, applied swags, other flowers and florals.

And here you have this classical theme just below the dome.

Five finials with floral tops.

It's just absolutely over-the-top in terms of quality.

And the tune selection helps us date the clock.

One of the tunes is Westminster, and of course, Big Ben was installed in 1859.

(clock tone playing) And that sound of the quarter hour striking became synonymous with clocks of this period.

And this clock has that, so we know that it had to have been made after that.

So it was top of the market.

Just an absolute fabulous piece.

GUEST: That's great.

APPRAISER: In its current state, in a retail setting, this probably has a value of somewhere to $3,000 to $4,000.

GUEST: Hm.

APPRAISER: Once it's serviced, this clock should easily make somewhere in the $6,500, $7,000 price range.

GUEST: Oh, that's great.
