Tokyoflash's latest Kisai watch is the Kisai Stencil, based on a concept design submitted by a math teacher named Heather Sable. It uses "negative space" to draw the numbers, a display that is cryptic at first but is easy to read at a glance once you've figured out the knack of it. — Read the rest

The TokyoFlash folks have a new crazy-ass watch out, the Broke, which tells time by displaying an animation of a shattered piece of stained glass. The bright screen must be pretty battery-intensive because they've added USB recharging, which is pretty nifty. — Read the rest

Tokyoflash, purveyors of fine eye-candy for your wrist, has hit another homerun with their latest LED watch, the Kisai Keisan, which uses long convex lenses to diffuse the LEDs underneath, producing a striking effect. And lest you fear that this watch is uncharacteristically simple to read, fear not: "Simply touch the button and digits will appear in four vertical lines. — Read the rest

TokyoFlash, my preferred vendor of crazy, addictive, nonsensical high-tech LED watches, has just launched the Kisai Tenmetsu, a super-thin OLED-based watch that flashes and transitions between three colors to display the time using a perverse and delightful system ("Red LEDs indicate 15 units, amber LEDs indicate 5 units and green LEDs indicate 1 unit, a combination of which present hours, minutes, months and date."). — Read the rest

TokyoFlash's new Nekura series watches are awfully handsome (even if they're disappointingly easy to read!) — I'm especially fond of this little puppy, known as the Tumbler. Wheels within wheels!

The Nekura series breathes fresh life into traditional time telling and is certain to be a fashion trend this season.

The masters of impractical high-tech wristware at TokyoFlash have pulled off another coup of LED wristwatch madness with the Infection watch, which uses seething colored LEDs to simulate a dancing Petri dish (and tell the time):

Twenty-seven multi-colored LEDs pulsate and move like cells across the curved face to present the time from beneath the attractive mirrored mineral crystal lens.

TokyoFlash has picked the winners in last month's giveaway of three Tibida watches to Boing Boing readers, and as a consolation prize, they're offering an 1100 yen ($11, 7 Euros or 5 British pounds) discount to readers who buy watches at the store from 6th March 2008 to 13th March 2008 — just use the coupon-code BOING when you check out. — Read the rest

TokyoFlash sent me one of their Tibida watches to play with in January. I've been buying TokyoFlash watches for years; they embody the perfect intersection of style, impracticality and blinky lights to tickle my nerdbuttons. The Tibida is no exception.

The face is a grid of circular white discs, each over a white LED. — Read the rest

The winners of TokyoFlash's impractical Japanese watch giveaway have been announced. Congrats to BB readers Dallas Cloud (Texas), Justin Russell (Washington) and Dylan!

TokyoFlash's Christian sez, "please also mention that as a thank you to all our customers we are running a Christmas giveaway. — Read the rest

New from TokyoFlash, purveyors of fine and impractical Japanese hipster novelty watches: the LED by Binary. It's a watch with a naked printed circuit board, on which are situated 10 LEDs, which glow to display the time in binary notation. ¥8900.00 — about $80. — Read the rest

New on the killer TokyoFlash watch site, the Pimp Watch — at $129, it's a little rich for my blood, but boy, that's some sweet watch action.

For many years, we've celebrated Tokyoflash's glorious and impractical contributions to horology: the company has set itself on a long path to imagine what a watch can be in an era where we all have unbelievably precise, self-setting timepieces in our pockets at all times, playfully experimenting with what a watchface can do while still telling the time (nominally, at least!).

Tokyoflash's Kisai Night Vision Wood LED Watch builds on their earlier work with beautiful, carved-wood bracelets, adding a wooden face backed with powerful LEDs whose glow can be seen through the smooth vegetable matter. It's a very futuristic look indeed. The watch charges with USB, and comes in sandal or maple, and it has a preprogrammed LED dance it does twice a day as a little show-offy gesture. — Read the rest

TokyoFlash's new Kisai Console Wood watch has a gorgeous sandalwood bracelet and a groovy LED-lit display that nestles directly in the sweet-spot between functional and ornamental. It comes with your choice of blue or green LEDs and red or dark sandalwood, and charges over USB. — Read the rest

TokyoFlash's new Kisai On Air watch uses an always-on touchscreen LCD to display the time; the "minute hand" points to the hour and displays the minutes. The watch has a bunch of fun animations and some limited customizability, too.

A multi-functional watch design, Kisai On Air features touch screen technology and displays the time and date.

TokyoFlash's new 3D Unlimited watch is a mirror-backed LCD watch with an EL backlight that displays time as faces on a cube. I'm inordinately fond of this kind of slightly impractical time-display, a kind of unapologetic use of time as ornament in a world where we all have network-synched clocks in our pockets. — Read the rest

This concept design for a Cheshire Cat pocket watch tells the time by the disappearing bits of the mad kitty.

The hours are affixed around the outside of the case in normal clockwise fashion. The cat himself is segmented into 5 minute intervals, the grin, appearing first, is 5 minutes, his head is the 10 minute mark, and each stripe is five minutes.
