Tell time with an aviation-style light show

Inspired by an aviation theme, the Kisai Blade watch features a turbine-style lens with digital tube LEDs that seem to rotate like a propeller.

The watch has two time settings. In Turning Mode, the blades spin and three blades light up in turn to indicate the hours and minutes. In Flashing Mode, one blade lights up to indicate the hour, and another flashes to indicate a five minute interval. Four LED dots by the 12 o’clock blade indicate up to four additional minutes to show the exact time.

To keep things fun, there’s also an animation mode where the LED blades light up and rotate “like a jet engine” at 15-minute intervals between 6 p.m. and midnight.

Priced at US$169, the black, silver or gold sandblasted stainless steel case comes with a choice of blue, green or red LEDs. The battery is rechargeable via USB.
