Tokyoflash Japan’s Kisai Online watch uses an accelerometer to hide the time from others

If you’ve ever had a reason for keeping the time to yourself, the latest offering from Tokyoflash Japan should appeal — the Kisai Online watch uses an accelerometer to reveal the time to the wearer while others see nothing but a stream of vertical lines. While the digital time display is characteristically unconventional, looking a little like the code behind the Matrix, it follows the recent Kisai On Air Acetate in actually being pretty easy to read. That is, assuming you’re able to turn it to face you. The design is based on a concept originally submitted to Tokyoflash by Sam Jerichow, a fan from Germany. It’s selling online for $169, but there’s a $20 discount if you order it before 10:30pm ET on Friday night.
