Neat-o watch manufacturer Tokyoflash has unveiled an awesome new concept watch which uses an e-ink screen to create a wraparound inverse display.

As seen over on the company’s blog, the e-Paper Timing watch uses a curved e-ink screen to “show the time digitally in the negative space.”

The company has even seen fit to include Bluetooth functionality, making the watch vibrate and display a message on incoming calls or messages received by the paired handset.

Sadly, it’s only a concept at the moment – which is a shame, because it’s the first of Toykopop’s peculiar designs of wristwear that I could actually see myself spending three figures on.
