Bizarre watch evaluates your thoughts and emotions

If you're habitually late, this watch is the perfect excuse. Invented in Japan, the Kisai Rorschach is a bizarre device that tells you the time while giving you a psychological evaluation.

Inventor Tokyoflash, famous for creating inscrutable watch faces, wanted to mimic the inkblot tests of Hermann Rorschach. The tests use a series of mysterious ink patterns to evaluate a patient's thoughts and emotions by their response as to what the patterns remind them of.

In a statement, the company claims the watch makes "reading the time simple".

Hours are shown in the top right, minutes in the bottom left, the rest of the screen is a reflection of these digits which creates the inkblot effect. The Kisai Rorschach uses e-paper display similar to that used on Amazon's Kindle range so its power consumption is minimal.

It has a battery life of two to three years and allows wearers to switch between black on white or vice-versa.

The watch also includes a power-saving sleep mode, which can be used between midnight and 7am. During this time it will display a different cryptic ink blot design on each day of the week.

In sleep mode, battery life can be extended to last up to three years and users can wake up the watch at any time by pressing a button.

But chances are, if you're running late, you don't need a RM594 (S$230) watch to tell you you're stressed.
