The One Mic star is known for his love of high-end timepieces and now he is going into business with private watch dealer Steven Brown to launch, a website offering limited sales of one classic watch a day.

The store will feature both new and used items from top brands like Rolex, Cartier and Breitling, among others.

Sharing the news on on Saturday (20Jun15), he wrote, "I'm excited to announce my new watch site @ownlyone will be launching very soon! Ownly One is the destination for high-end watch sales."

Nas has also opened up further about the new venture on, revealing the partnership with Brown seemed like a natural step for him.

He tells the publication, "I feel like I'm a walking commercial, and when I wear a watch, the world sees it. I can't tell you how many times people bought certain watches I would wear and would tell me about it: 'Yo, I got this 'cause I saw you with it'. And I'm drawn to the history of watches and the business of watches, automatically."

To mark the upcoming launch of the business, Nas and Brown are giving fans the chance to win a vintage Rolex simply by signing up to their e-mail newsletter.

He adds of their choice of prize, "A Rolex, that's a watch many people may want in life but never, ever get and I just felt like, 'What's better than to bless somebody with a vintage Rolex?' It's classy to me." is Nas' latest endeavour - he recently announced a partnership with bosses at New York City restaurant chain Sweet Chick to help expand the chicken and waffle company's presence across the U.S.
