GUEST: It's a Tiffany carriage clock.

We've had it for about 25 years.

It's in its original case, and it has, I think, most of its original tools with it as well.

We purchased it out of a abandoned storage unit.

When we purchased the clock, we were told that the storage unit belonged to a woman from Uruguay who had had a ill-fated romance with an American diplomat.

APPRAISER: Uh-huh.

GUEST: And so, the unit had been abandoned, and, uh, we believed a lot of her belongings to be inside.

APPRAISER: So, what you brought in today is a very special example of a carriage clock retailed by the Tiffany clock company.

Made in France for them to retail sometime around circa 1890.

Could've been sold in Europe in a Tiffany location.

Uh, but Tiffany, of course, is world-renowned for being anchored in New York City.

The fact that the case is six-sided makes it a very unusual example; most of them were four-sided.

GUEST: Mm-hmm.

APPRAISER: So, having the additional two sides probably put it on the scale of a special order.

In the front, you have the retailer's name, Tiffany & Company, and then you have this porcelain panel with the four puttis and the garlands.

You have these side porcelain panels representing the four seasons.

When we look at the back, we have the three hammers, one being for the alarm, the other two being for the strike sequence.

We also have two gongs, and down on the bottom left hand corner is the alarm.

Very unusual to have that in that location.

Most of the time, the alarms are indicated from the front.

And if we tip it upside down here, we can see the lever that indicates that it's a "grande sonnerie" mechanism, and that means that it is a complication, that it does more than just strike the hour, it actually strikes the hour and quarter-hour and will do that on demand, and it does that by depressing this button here at the top.

You can see remnants of the original gilt wash, so this is a brass case originally fire-gilt.

We conservatively estimate this clock to have a retail value of $7,500.

GUEST: Wow, wow, I didn't ex-- I didn't expect that.

I was thinking, "Okay, maybe $3,000."

Okay, that's fantastic.

APPRAISER: Very few carriage clocks achieve that level of, uh, monetary value.
