TokyoFlash’s watches aren’t known for their subtlety, but, despite taking cues from the aviation world, its latest design looks a bit more grounded than previous offerings. The Kisai Blade sports a custom-made turbine-style lens, and uses tube LEDs that rotate, like an airplane propeller, to tell time. The LEDs operate in three different modes, “Turning” uses a constant cycle to light up hours and minutes, while “Animation” turns your wrist into a rave with a constantly spinning diodes. In case you’re wondering how it displays the finer minutes, “Flashing” mode slowly flashes the minute hand at the standard five minute intervals, and four dots indicate minutes one through four. The timepiece uses a USB-rechargeable battery that can go a month between charges and is available with red, blue and green LEDs, and gold, silver and black bands; there’s a leather band option, too. If the Blade strikes your fancy, you have the next 48 hours to snatch one up for the launch price of $139, or if you miss the sale window, $159.
