A、A digital watch with the date and time. B、A digital watch with yellow gold plating. C、A mechanical watch with a leather strap.

W: Good afternoon. Can I help you?
M: Yes please. I’m looking for a watch to give my mother as a birthday gift.
W: Could I ask what the price range is in your mind?
M: Well, I don’t think I can afford an expensive watch from a famous maker, such as Rolex. I want to have a look at your watches on special. My friend told me they were worth the prices.
W: We are honored to hear that. Would you prefer a metal strap to a leather strap?
M: Oh, yes. Leather straps are for young people like myself. Metal straps look more classical. It’s therefore suitable for my mother, I think.
W: How about this one, a gold-plated strap?
M: Yes, it’s very nice, but I’d prefer a mechanical watch, one with hands, other than a digital watch.
W: How about this one? It comes with yellow gold plating, it has the date, it is mechanical and, of course, it has hands.
M: Oh, it’s very nice, especially the one with yellow gold plating. I think she would like a watch that shows the date and the time. This one would be just right for her. Is it possible to have something written on the back?
W: Of course, sir, but there will be a small additional cost. What would you like to write?
M: I think "To mum" and then the date beneath.
W: No problem, sir. It’ll be ready tomorrow. If you want us to deliver the watch, please put down your name and address.
M: Good, if you can help send it to my mother directly, it must be a big surprise. Let me give you the address.
