Jay Z is known for many things: talented rapper, husband of the beautiful and equally talented Beyoncé Knowles, clothing designer, record label guru, Rolex watch fan, and good citizen.

Today, September 11, 2009, in remembrance of the tragedy that struck our nation eight years ago, Jay Z is giving a charity concert, called “Answer the Call” at New York’s Madison Square Garden. Tickets are going for $50 and Jay Z has said that he will donate all proceeds to the New York Police and Fire Widows’ and Children’s Benefit Fund. The concert is expected to raise between $750,000 and $1 million dollars.

On a personal level, today is also an important day for the rapper as he is set to release his 11^th album, this one titled “The Blueprint 3.” Ironically, it was eight years ago today that Jay Z released his first “Blueprint” CD, when he nor anyone else would have any idea how tragic that day would turn out to be.

We can expect that during today’s concert Jay Z will rock his Rolex Masterpiece. Throughout his career, Jay Z has been a loyal fan of Rolex watches. He’s sported an all stainless steel Rolex Day Date, a Rolex Masterpiece and other styles over the years. When asked about the Rolex Masterpiece a few years ago in an interview with New York Magazine, Jay Z said the following: “It’s a Masterpiece Rolex,” Jay-Z said demurely, allowing an inspection of the diamond-studded watch twinkling on his wrist. “I was, like, the first one in the country with it. I try to stay on top of things. It’s a little hobby, know what I’m saying? I read the Robb Report, the duPont Registry, things like that. I tend not toward expensive — more toward exclusive.”

This point is made in a line from one if his new songs titled “30 Something” (he’s 39), that says “I don’t got the bright watch, I got the right watch.”

And that about sums it up. With a fortune estimated at who knows how much, a hundred million dollars maybe, Jay Z can afford to wear any watch of his liking. Like most celebrities, he chooses Rolex.
