Clock watch

Jay-Z and Ralph Lauren have both found time to drop by the ClockTower Building at 1 Main St. and check out Brooklyn’s ultimate trophy apartment.

That’s where developer David Walentas, the man behind the DUMBO neighborhood, has enlisted Prudential Douglas Elliman broker Raphael De Niro’s help to sell his $25 million triplex penthouse. The 7,000-square-foot apartment boasts bird’s-eye views, through four giant clocks with glass faces, of the Statue of Liberty and the Empire State Building — a good fit for Jay-Z and his “Empire State of Mind.”

The four-bedroom, 3½-bath condo also includes a glass elevator and a staircase made of stainless steel, glass and oak. The residence takes up the 16th through 19th floors and includes a 400-square-foot “crow’s nest” roof deck.

The apartment’s clocks are the subject of an art installation by Vera Lutter that will be shown in a Larry Gagosian gallery, and the condo was featured in Spike Lee’s “Bamboozled.”

Close quarters

You might remember Glenn Close’s bunny-boiler character in “Fatal Attraction” residing in a gritty yet glamorous Meatpacking District pad that was stupendously ahead of its time. But in real life, Close has been living in the exclusive Beresford building at 211 Central Park West. And now she’s putting her two-bedroom, two-bathroom co-op there on the market for $11.8 million.

Rock Hudson once owned the 19th-floor residence. Current neighbors include Jerry Seinfeld, John McEnroe and Vikram Pandit. Close’s co-op has a private elevator landing, views of Central Park over the Delacorte Theater and south past the Museum of Natural History. The apartment features a fireplace, two terraces and a maid’s room. Corcoran Group broker Robby Browne has the listing.

Close also has a pad at 140 Charles St. and homes in Bedford and Palm Beach, Fla.

The buyout

Being a billionaire comes with some unusual privileges — like keeping a mansion around to stay in while your bigger mansion is being fixed up.

Blackstone Group CEO Steven Schwarzman has just sold his East Hampton home for $6.25 million. He put it on the market last August for $7.2 million. The buyers are power couple Thomas Gallagher and Alice Jarcho-Gallagher. Built in 1987, the four-bedroom home sits on 2.1 acres and comes with a tennis court, pool and pool house.

Schwarzman bought the 3,200-square-foot home for $2.3 million in 1996 and later stayed there while the Water Mill estate he bought for $34 million in 2005 was being renovated.
