As more and more of us (millionaire non-astronauts) are traveling into space, we need a means of telling time. Apparently, the zero-gravity environment in space is enough to render earthly timepieces, obsolete. Watch-maker, Seiko, has answered our challenge by producing the Spring Drive Spacewalk watch. Richard Garriott, the sixth private-citizen space explorer, will wear the watch on the outside of his spacesuit (it's called MARKETING). You can get one of the remaining 97 watches for $25,000 USD.
