Seiko's Spectrum e-ink watches around your wrist, now's your chance. If you're willing to pay a pretty penny for it, that is. Seiko, which originally put a price of about $2,000 on the watch, has now decided to offer it up on eBay as part of a charity auction for British charity Help a London Child. The auction is expected to start on March 19th and run through March 25th. Seiko is only making 500 of these, so if you want one, get ready to start bidding.
