A gold pocket watch that belonged to the Titanic’s wealthiest passenger has sold for almost $1.5 million, over seven times more than what it was predicted to sell.

The watch, which belonged to John Jacob Astor IV, had been estimated to sell for $189,000 at an auction over the weekend. However, the watch ended up selling for $1.485 million, far exceeding expectations, according to the Henry Aldridge and Son auction house.
