Nubeo is a company known for jellyfish-shaped watches. In collaboration with the basketball star Kobe Bryant, this luxury watch brand creates a limited-edition line.

Composed by high-tech sport watches, the collection’s prices start at about $21,000 and topout at $285,000. The Black Mamba series, in honor of Mr. Bryant’s nickname, will be launched at Baselworld 2009, in Basel, Switzerland, and will go on sale this fall.

Ivan Castro, the jewelry designer who co-founded Nubeo in 2004, is a huge basketball fan and reached out to Mr. Bryant’s agent and marketing manager.

Another luxury watch signed by Elton John, to fight against Aids, will be presented by Chopard at the Baselworld 2009.

The new Chopard watch features a white or pink gold jeweled dial, jeweled bezel and a cocodrile leather bracelet, available in three different colours: pink, brown or black. It also has a quartz chronograph movement.

A portion of sales will be donated to Elton John Aids Foundation.

With Baselworld 2009 not far off, Swiss watchmaker Concord has revealed tantalizing images of an avant garde new timepiece, the C1 Quantum Gravity.

511 components come together in unison to create what has to be one of the most incredibly complex watches ever built.

An aerial bi-axial tourbillon mechanism. A vertical power reserve. Individualist seconds. A stripped-down dial and spectacular volumes: the latest specimen from the C Lab Series defies all theories !

The big news for Maitres du Temps at Baselworld this year will be their new Chapter Two watch, but the beautiful Chapter One watch should not be overlooked.

To help emphasize that point, Maitres du Temps is releasing a new limited edition, featuring a jet-black dial and rollers set in a high-contrast white gold case.

Whereas the standard Chapter One watch comes in blues and gold, “the Black version is a monochromatic delight.”
