Is selling a watch for another watch with a difference in price considered riba (usury or interest)?

Question:
May Allah reward you. He says: I have a used watch that I wanted to sell to a watch shop and exchange it for a new watch of a different type from that shop. The shop owner said to me: We will sell you one of these watches for three thousand riyals, and we will take your watch for one thousand riyals, and you will pay two thousand riyals. Is this sale riba?

Answer:
This is not riba, because the watch is not made of gold or silver. Riba is only in gold and silver. As for a watch made of something other than gold and silver for women, there is no harm in selling it for another watch with an increase or decrease.
