Swiss watchmaker Hublot has launched a new diamond-covered 18k white gold Big Bang tourbillon watch, which costs a whopping €2 million ($2.8 million).

The new Hublot Big Bang Watch set in 18 carat gold with a gold Big Bang tourbillion comes studded with as many as 142 carats worth of baguette diamonds, which covers the case, dial, and bracelet.

A total of 637 baguette diamonds along with one rose cut diamond on the crown dress up this masterpiece.

Serving as Official Timekeeper of the Tour Auto for the sixth year running, Audemars Piguet is launching a limited edition watch to commemorate the event.

With its distinctly retro touch, the 2011 Audemars Piguet Millenary Tour Auto Chronograph masterfully captures the vintage spirit of the Tour Auto race.

The new watch is available with a 47 mm case, fashioned from steel. Its back side is embossed with the Tour Auto logo.

Glashütte Original released a very nice and legible Perpetual Calendar in its flagship Senator collection.

The reference 100-02-25-05-04 features a red gold case which pairs nicely against the black-dial with white Arabic numerals.

The moon phase disc also fits onto the dial nicely and is adorned with silver stars and a radiant silver moon.

Harry Winston has unveiled at Baselworld 2011 the Opus Eleven, created in partnership with Denis Giguet (MCT).

Three overlapping cylinders on three levels are configured to deconstruct time – the main circle is the hour’s domain, flanked by two pavilions.

One sub-circle shows the minutes on a jumping disk for the tens and a running disk for the units; the other shows off the beat of the big titanium balance-wheel.

To mark the 2011 Baselworld Fair Hublot is presenting a world first, with a minute repeater watch featuring two “Cathedral” type gongs, a tourbillon and column wheel chronograph, with carbon fiber bridges, in a case made from carbon fiber.

This is a perfect illustration of “Fusion” between great watchmaking tradition and the technology of the future.
