Posh Swiss watch firm Ulysse Nardin has broken its silence about its upcoming motion-powered phone, releasing specifications for and pictures of the exclusive handset.

The Chairman: charged by kinetic energy

As previously reported, Chairman boasts a “kinetic rotor system” that pumps power through to a back-up battery each time you move the talker. The phone can be charged from the mains too.

Sadly, as with most Vertu-esque phones, Chairman’s other technical specifications aren’t much more than seaworthy - despite the ship's anchor iconography.

Nope, she's not included

It has a 2.8in touch-sensitive screen, a 5Mp camera and Wi-Fi capability – all three of which are good to have, but hardly groundbreaking, and come as standard on many free to £100 ($143/€106) phones available on the high street.

But, if you’re worried about security, then you’ll probably be impressed by the inclusion of a biometric reader. An integrated cigar cutter and lighter would have been cool too, but are absent.

The rotary motor sits in the Chairman's rear

Five Chairman models have been created, but aesthetics appear to be the only differences.

For example, the “Rose Gold & Blue” model has light blue body with gold coloured keys and rotary mechanism. But the “Steel & Blue” model, as the name suggests, swaps the gold for steel.

Five colour styles of Chairman are available, including the pictured "Stealth Black"

A formal launch date or price hasn’t been confirmed yet, but such details will probably only be given “upon application” anyway. ®
