Paul Alteri from Bob’s Watches, an online exchange for used Rolex watches, would like to introduce you to his two favorite Rolex models at the moment: the Rolex Daytona and the Rolex President.

In today’s world, the Rolex watch is a commodity that continues to grow in value on a variety of levels. The cost of new Rolex watches continues to rise by 5 to 7 percent each year, which in-turn increases the value of pre-owned Rolex watches. Two such models that have caught the eye of Rolex collectors around the world are the Rolex Daytona "Paul Newman" and Rolex President. They are without a doubt two of the hottest models on the pre-owned Rolex market for women, with their classic yet innovative styling. Because of their versatility and unforgettable designs, tennis players and fans have had a love-affair with both Rolex watches both on and off the court. Many women can now be seen wearing men’s watches like the Men’s Rolex Daytona in Rose gold as worn by tennis great Ana Ivanovic.

This spring Venus Williams relaunched her clothing line EleVen, that had suffered due to the bankruptcy of its initial exclusive retailer Steve & Barry's. The American is now making another step forward, taking her EleVen sportswear to New York Fashion Week.

Venus is still fresh off her Olympic women’s doubles golden success, but we know she is planning an unconventional show for September 12, while the exact location is yet to be determined.

I'm not sure of the exact location because I just got back from the Olympics. I'm still getting updated. Who am I? Where am I? Why?

Five years ago Venus received an associate degree in Fashion Design from the Art Institute of Fort Lauderdale.

Today, Venus advanced to the quarterfinals of the Western & Southern Open, beating seventh seed Sara Errani 6-3 6-0 in the third round. Seed No.3 Samantha Stosur is awaiting Venus in the quarterfinals.

Have a look at our yearly overviews of Venus' EleVen designs in 2011, 2010, 2009 and 2008. Note that in 2012 Venus has given up the infamous lace, fringe and awkward designs, directing the path of her brand towards more elegant and toned-down style.

Venus and Serena Williams both won their Tuesday's matches at the Western and Southern Open – Venus battling past the London Olympic singles semifinalist Maria Kirilenko 6-3 6-7(5) 6-2 in the first round and Serena, gold medalist in singles, beating Eleni Daniilidou 6-3 6-4 in the second. In the post-match interview, Venus revealed that her goal is to qualify for the Rio de Janeiro Olympics in 2016 and she would play even if crippled, while Serena, winner of 44 titles, couldn't believe that the Cincinnati title is not in her résumé.

At present, Venus is dealing much better with her Sjögren's syndrome and the 32-year-old is nowhere near ending her career:

I'm very excited about Rio. That will probably be my last one. By that time I'll be creeping up in age. That would be an awesome career. I figure I'm going to spend more time retired than pro, so while I'm here I'm going to go for it. If I'm on one leg and I get to Rio, that's great, too. That's my whole goal: continue to work on my health and stay as healthy as possble – if that happens, I believe I can get to Rio.

At the 2012 Summer Olympics, Venus won women's doubles gold with Serena.

Here's how the younger sister got lost in the numbers:

I've won this tournament. I have. When it wasn't this big. But it counts. I did win this tournament, didn't I?

Maybe I didn't. I can't keep up. I don't think I did. Okay, whoops. Yeah, I didn't win this tournament. I thought I did. I really thought I did.

So many titles, who wouldn't lose track! (photos courtesy of Moo's Tennis Blog)

Maria Sharapova is not defending her Cincinnati title this week, missing her second straight tournament after the Olympic silver, due to a stomach virus. However, you know the Russian always has her hands full and during the time off the tennis courts she is launching her line of candy called Sugarpova.

On her Facebook page, Sharapova gave us a glimpse of how the sweets will look and invited everyone to join her on August 20th at Henri Bendel on 5th Avenue. For those not in New York, Sharapova ensured a live stream on her official website.

Have to love those Facebook comments! One commentator hopes that the candy will make Sharapova stronger and more cheerful.

Maria next time crush those Williams sisters with your game, I hate their winning against you. Eat some chocolate and be lively, you look too cold, like your country Russia, cheer up.

Petra Kvitova’s breakthrough 2011 season included six titles, while this year had seen a drought, without even a WTA final or Top 10 wins, up until now. In the final of the $2,168,400 Rogers Cup, Kvitova edged Li Na 7-5 2-6 6-3, while earlier in the tournament she recorded wins over world No.10 Marion Bartoli in the third round and world No.8 Caroline Wozniacki in the semis.

The first set of the final lasted more than an hour and Kvitova needed five set points to win it, while in the second set seed No.10 Li went on a roll, winning 16 points in a row for a 4-0 lead and soon after 6-2. After the mid-match slump, the fifth-seeded Kvitova steadily went through the third set, and one break of Li’s serve ensured her advantage.

Kvitova now has eight titles to her name: Hobart (2009), WTA Championships, Linz, Wimbledon, Madrid, Paris, Brisbane (2011) and Montreal (2012). Li has fallen to 0-3 in finals this season, while her all-time record is 5-8. They have both climbed in the rankings: Kvitova from No.6 to No.5, and Li from No.11 to No.9.
