GUEST: I inherited it. I've never seen the inside of it before, and I wasn't even sure that they were real diamonds, so I don't know anything.
APPRAISER: The first thing you notice is, it's very beautiful.
GUEST: Beautiful.
APPRAISER: It has all this... pretty French enamel. That's probably where this enamel was put onto the case. Intertwined with the enamel, we do in fact have diamonds. They are what we call rose diamonds, and rose diamonds have a flat bottom, and they're faceted with just a few facets on top. Now, if we had a watch like this-- the diamonds, enamel-- it may be a $1,500 to $2,000 watch. But your watch is a little bit better. If we flip it over now... Beautiful white porcelain enamel dial, and we see that it's signed by Tiffany and Company. Tiffany and Company didn't make watches. They're the company that retailed them. Now we have a watch that's probably worth $3,000 to $4,000.
GUEST (laughing): Oh, God. Oh, dear.
APPRAISER: There was a company that started using Tiffany as one of their main retailers of their product in New York in 1854. If we turn the watch back over and we open up the case, it tells us it's made by Patek Philippe and Company, which is the finest maker of Swiss watches in the world. There may be some just as good, but there's none better. And there's also a serial number in here. If we look up the serial number, this watch was manufactured in 1890. So now we have the diamonds, the rose diamonds, the enamel. We have Tiffany and Company. Now we have Patek Philippe. You ready?
GUEST: Yes.
APPRAISER: $8,000 to $10,000 at auction.
GUEST: Oh, good grief-anelli. Oh, that's unreal.
APPRAISER: You have to start wearing it, somewhere.
GUEST: I'll wear it every time I watch the ANTIQUES ROADSHOW.
APPRAISER: (laughs)
