I know what you’re thinking, “holy shit, we have a new president!” And also, “damnit Geekologie Writer, hit me the latest in time-telling devices”. Well you got it, son. The Kisai Keisan is the latest in Tokyoflash’s wrist flasherdashery. If you can add, you can tell what time it is on the Keisan.

Calculate the time with Keisan. Simply touch the button and digits will appear in four vertical lines. Add the digits in each vertical line to read the time. The date is displayed in the same way after the time. The time and date can be accelerated by pressing button A again. To find out more, take a look at the interactive manual to the right.

The Keisan is available for $255 in black with red or green LEDS, and silver with orange or yellow LEDs. But hurry — they’ll be gone in a Tokyoflash! ZOMG, I think I just reached a new level in L337 advertising: +30 selling, -20 dignity! I swear, I could sell fire to Satan — or cans of bitch to my ex-wife!

Hit the jump for a bunch more pictures of the flashery.
