Q & As

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Technology at its finest A watch with a built in GPS! Why has no one thought of it before? Wherever you are in the world, it will adjust ot the correct time - exquisite. I saw this at Salon QP in London in November and not only did its looks blow me away but the functionality and the price are hard to beat too. It really is a must-have if you travel regularly; even if you don't, it will still be a thing of beauty on your wrist. 03 December 2012
