Watch out for those dating apps!

A man’s pricey watch was stolen by a date he met on OKCupid, cops said Thursday.

The 58-year-old Manhattan man dined with the mystery woman at the Scalinatella restaurant in Midtown on July 31 — before the couple headed back to his Upper East Side apartment, according to authorities.

After a quick nightcap at the man’s pad, the woman asked him for $20, grabbed his $10,000 vintage Audemars Piguet watch and took off, cops said.

The man — who said his date spoke Croatian — never saw the woman or the timepiece again.

The suspect, described as tall with dark hair and a slim build, could be seen on surveillance video from the eatery. Police released the images of the watch thief on Thursday.

The theft was the latest case of a mystery date taking off with expensive jewelry and cash.

Criminal vixens, who troll dating apps and trendy clubs, have zoned in on pricey watches and fancy jewelry when choosing which mark to rob blind.

In 2017, a Russian masseuse pleaded guilty to drugging and robbing two men she had met on dating sites.

Viktoriya Nasyrova, using the alias Rachel Bergman, stole two rings, one necklace, a money clip totaling over $50,000, and a Rolex from the men.

Another woman stalked her prey at the popular nightclub 1 Oak in August of 2017.

After accompanying a man back to his Manhattan apartment, she waited for him to fall asleep before leaving with his $50,000 Rolex Presidential watch and $20,000 gold Cuban link chain.

In 2015, New York Knick Derrick Williams was robbed of $750,000 in jewelry at his Tribeca apartment by two women using false names.

Williams met the two gals at a Meatpacking District club on Dec. 19, 2015, and took them back to his place to party.

That’s where they found — and made off with — a Louis Vuitton jewelry case holding three-quarters of a million dollars’ worth of bling.
