A watch by Swiss luxury brand Patek Philippe has sold for over $ 31 million, the highest price ever paid for a watch at auction.
It is the only version of the timepiece ever produced in stainless steel, and the alarm sign is marked with a special inscription, "the only one."
The watch has a reversible case in black and pink gold, 18 carat solid gold plate and is fastened with a ribbon made of black, hand sewn alligator leather.
It also includes all the features one would expect from a luxurious timepiece: gold Breguet numbers, a hand-guilloched hobnail center, a one-year display and a plethora of sub-dials.

Its sale on Saturday to a mystery buyer for 31 million Swiss francs, or $ 31.1 million, promotes it to a very exclusive club.
Saturday's sale also broke the previous record for the most expensive wristwatch, set in 2017 by a Rolex Daytona owned by the late American actor Paul Newman.
A total of 50 lots were auctioned off in Saturday's sale, collecting 38.6 million Swiss francs ($ 38.8 million) for Duchenne muscular dystrophy, a genetic disorder that causes progressive muscle degeneration.
