Celsius X VI II LeDix Furtif

We’ll admit, it doesn’t exactly roll off the tongue. But as it’s made from 700 mechanical parts bonded in a carbon fibre case, we think it deserves a name with some gravitas. Part phone, part timepiece, a tourbillon throbs beneath its sapphire crystal breast-plate.

It’s not just for show, though: by answering your phone you actually add three hours to the standby battery life. No fewer than 35 engineers work on each unit – and there are only going to be 24 made. At £190k a pop, it’s probably worth taking out insurance on this one.

The LeDIx Furtif has a patented mechanical hinge, which harnesses the kinetic energy generated by the user

There are 700 parts in LeDix Furtif, including 330 in the watch movement section alone
