Purveyor of weird watches, Tokyoflash, has blended the old with the new in its latest creation, the Kisai Round Trip Pocket Watch. Designed to attach to a key chain, belt loop or even on a chain in your top pocket like a traditional pocket watch, the Round Trip continues Tokyoflash’s history of releasing timepieces that make telling the time a puzzle to be decoded.

Instead of its usual, (that is to say, unusual), wrist watches, the Kisai Round Trip Pocket Watch displays the time using rings of flashing LEDs – not unlike its Kisai line stablemate the “Broke” we looked at last week. The inner ring of orange LEDs display the hour, while the outer ring of blue LEDs designate the minutes in three minute chunks. An additional two green LEDs located on the bottom of the outer ring are used for single minutes. The line of green LEDs emanating from the center appear to be just for show.

At first glance the watch face might seem indecipherable but the orange and blue LEDs are positioned relative to the hours on a traditional clock face. Tokyoflash says users will be able to tell the time at a glance but it will definitely take some getting used to. So much so that for the first few days, by the time you’ve figured out the time there’s every chance it will have changed.

To conserve the watch’s battery users need to press a button to illuminate the LEDs, with the relvant chunks flashing to indicate the current time. The Round Trip is also USB rechargeable so it can be plugged into your computer with the provided cable to top up the battery. A full charge takes 3.5 hours and will last around one month. The LEDs can also be set to animate once every 15 minutes between 18:00 and 24:00.

The Kisai Round Trip Pocket Watch is housed in a stainless steel case and comes with a key ring. It is water resistant to 3ATM (30 meters), comes with a one year warranty and is available from Tokyoflash for US$73.
