Kisai Keisan Black LED Watch

Keisan combines a raised convex bubble lens with optical technology precisely engineered to diffuse the advanced low energy Japanese LEDs, creating a bright, magnified lighting effect.

One of the most futuristic watches available from Tokyoflash Japan, Keisan is a streamlined design made from high grade aluminum which ensures a lightweight, comfortable feel on your wrist. Finished with a pristine polished alumite coating, it has a smooth, bright appearance, unlike any other material.

An animation has been programmed into the LED module so that once every minute for 12 minutes after the time is displayed, the LEDs light up and move in a sweeping formation from side to side. A stylish effect that brings the watch to life.

Keisan is available in black, with red or green LEDs and is a must have design for anyone interested in futuristic watches.
