A blond femme fatale charged with stealing pricey watches from a string of wealthy men was sentenced ​Tuesday to five years’ probation for targeting a restaurateur.

Alexandra Martinez, 21, dodged jail time as part of the sweetheart deal she struck with prosecutors in September.

She pleaded guilty to third-degree grand larceny in Manhattan Supreme Court in exchange for probation and was ordered to pay $9,000 in restitution to numerous victims.

In the Manhattan case, the curvy grifter only had to admit guilt to swiping L&W Oyster Co. restauranteur Jared Siemens’ Rolex July 11, 2015.

The high-end seafood restaurant on Fifth Avenue counts Jason Weiner — the brother of disgraced ex-Rep. Anthony Weiner — as one of its owners.

Siemens took the temptress back to his Kips Bay luxury high-rise after meeting her at a bar earlier that night, he told cops.

As he freshened up in the bathroom at about 4 a.m., Martinez snatched his Rolex from a counter and dashed out the door.

In August 2016, she allegedly ripped off several watches, jewelry and electronics from JPMorgan exec Michael Briese. After taking her back to his $1.8 million condo, he made the fateful error of nodding off, court papers allege.

She was also sentenced to five years’ probation in Brooklyn last month for pulling the same scam on a slew of moneyed men.

Vincent Theurer Jr., whose dad is CEO of Approved Oil and Ron “Prince Ron’’ Zoldan, whose dad owns the country’s largest pyrotechnics retailer, fell for the vixens’ wiles, according to court papers.

Her defense lawyer, Marianne Bertuna, declined to comment.
