Moet & Chandon will be the official champagne of the US Open, the largest sporting competition in the world.

The sponsorship includes an on-site suite at the US Open, which is held in the Queens borough of New York.

The Moët & Chandon luxury suite will not only serve as a celebration station for attending guests, but host an auction to benefit the corresponding charitable effort titled “Cheers for the Champions.”

French luxury house Louis Vuitton has released a unique Tambour Diver Chronograph for Only Watch 2011 charity.

It was designed in collaboration with a young boy afflicted with Duchenne muscular dystrophy named Paul Pettavino.

The sporty timepiece is made of black gold, which is white gold that’s been given the old PVD treatment. ‘Only Watch 2011′ is engraved in the back.

The winning bidder for a private lunch with billionaire Warren Buffett has set a new record for the cost of dining with the investor, after pledging $2,626,411 for the meal.

The winning bid at the annual charity auction broke the record set last year by a little more than $100.

The opening bid started at $25,000. When the charity lunch began in 2000, this was the price of the winning bid!

Bottega Veneta have launched a special keyring for Japan and in particular to help the people struck by the earthquake and tsunami in March 2011.

It will be on sale in Bottega Veneta boutiques and on bottegaveneta.com, at a retail price of $210 USD. All proceeds will be donated to the Japanese Red Cross.

MB&F returns to the Only Watch charity auction in 2011 with another emotionally charged piece – this time in collaboration with Chinese artist Huang Hankang.

HM4 Only Watch features a solid gold panda bear riding on top of the HM4 jet, which he controls with reins made of twisted gossamer filaments made of gold.

The panda was hand-carved and then cast in 18k white gold using the “lost wax” technique.

The brothers behind Canadian fashion label Dsquared2 have unveiled a fashion project of a rather different kind, dressing up a Mini Cooper S in aid of charity.

The twins’ model has been “armed for adventures of all kinds,” with a large front guard, rally-style headlamps and a spare tire mounted to the tailgate.
