Ultra-luxury Swiss watchmaking house Audemars Piguet has launched two new stunning watch and necklace sets.

There are two sets of matching 18K white gold and diamond watches and necklaces for women, the Coup de Theatre and Carnet de Bal. Both watches use the AP calibre 2046 movement with manual winding (18 jewels) that beats at a frequency of 21 600 vph and provides 42 hours power reserve.

The “Carnet de Bal” series (above) was inspired by flower arrangements, creating a glittering floral spray of diamonds along the wrist and around the neck. The 18-carat white gold timepiece includes 481 gems of varying cuts totaling 59.53 carats. The matching necklace has 1,039 round, brilliant, marquise, pear, and baguette-cut diamonds.

Swissbit - a Flash memory company - and Victorinox - the maker of Swiss Army knives - have teamed up and joined forces with Bonfort- the popular penknife company – to create their Prestige line of USB drives.

The exquisite, limited edition executive present memory sticks come in white or yellow gold and are finished with over 600 brilliant-cut diamonds and finished to the highest level of quality. The USB key can be switched out if you decide to upgrade to a higher capacity drive.

Swissbit’s Prestige Swiss Army USB keys start at around €980 ($1,450), which we imagine will be for a silver version. Expect that price to climb considerably for the gold units and the diamond-encrusted ones.

Bonfort also offers an engraving service, in case you want your Prestige to be just that bit more exclusive ^_^
