Tokyoflash Japan is infamous for its abstract watches that are almost impossible to read without a manual — just look at the Kisai Rogue Touch Pocket Watch as one example — but the company's latest offering seems uncharacteristically user-friendly, if not exactly conventional. The Kisai On Air Acetate features a monochrome LCD with a single clock hand that tells the hour by its position and the minute by the numbers it's made up of. (Spoiler alert: the time in the above image is 10.20.) The simple interface is driven by touch and looks very logically designed, with nice features like slide-to-unlock and the ability to set the time by rotating your finger in a circle. It's available now in navy blue or white for $159, but if you order before 9.30pm ET on Friday you get $20 off and free shipping.
