Swiss luxury phone manufacturer Gresso has developed a new luxury phone that features six independent Swiss clockwork mechanisms - a device that would be better classified as a fancy timepiece than a high-powered feature phone.

The clocks are integrated into the back panel of the World Time collection phone and display the times in Tokyo, Moscow, Paris, London and New York ("the five main world business centers"). The extra clock-face can be adjusted to show the time in a user's selected location.

On the front of the phone, consumers will find a numeric keypad. Each key has been crafted from a single sapphire crystal and manually polished with a diamond tool for a "pleasant tactile sensation."

Additional features include titanium alloy casing, Italian leather detailing and two 97-carat sapphire crystals adorning the Roman figures on the back panel.

Gresso's Luxor World Time phones are not for those after a high-powered smartphone - the technical specs seem rudimentary in today's fast-paced high-tech market.

The screen resolution measures in at just 240 x 320 pixels, the 30 MB of internal memory can only be expanded up to 2GB with a microSD card and the camera won't be capturing much worth looking at with a resolution of 2MP.

If you are in the market for a smartphone with more bling than brains, Austrian jeweler Peter Aloisson is currently selling what is most likely the most expensive smartphone on the market - a 1.79 million euro Apple iPhone 3G with a rare 6.6 carat diamond home button, 138 brilliant cut diamonds and white, yellow and rose gold casing.

It makes the diamond-encrusted iPhone 4 made by British jeweler Stuart Hughes look like a bargain at just under 15,000 pounds (€17,000).

Consumers set on having six clocks in their pocket and particularly fussy about the look of their phone can modify the materials of the World Time phone (fancy a bit of pink crocodile leather?) using Gresso's personalization service.

The luxury phone sells for $6,000 and is available now.
