The trouble with buying a watch on the high street is that you might end up meeting someone with the same watch.

TechnoMarine aim to stop this with this limited edition diving watch.

Teaming up with world record breaking Italian free-diver Umberto Pelizzari the company has created just 80 watches that come with an 18kt solid rose gold case and a certificate signed by Umberto Pelizzari.

What else do you get for your £10,250? Hour, minute, second, day and date functions, oh - and water resistance to 20atm/200m/660ft.
