You might mistake Tokyoflash's Kisai Night Vision Wood watch for a carved bracelet with no other function than to look like a wood model of a watch. Push a button and hidden LEDs come to life, illuminating the face with the time.
The watch doesn't tell time in the usual way. A flashing dash around the outside of the face indicates the hour while the minute numbers are displayed inside. It's a pretty simple system once you get used to it. It also displays the date using the same system.
The original Kisai Night Vision was made mostly out of stainless steel and looks like a high-tech watch should. The wood version, however, is a minor stroke of genius. Rendering the watch in a natural material really highlights the strangeness of the hidden LEDs.
The Night Vision Wood is crafted from natural wood with a laminated face and is rechargeable via USB. It takes 3.5 hours to charge it up and it should last for a month on a full charge.
While the LEDs can be activated with the push of a button, the watch can also be set to show itself off every 15 minutes between the hours of 6 p.m. and midnight (when it's expected to be dark enough to really pop) with an animated light sequence.
The $149 watch (roughly £88, AU$159) is a limited-edition offering. Currently, only the maple models in both red and blue LEDs are still available, so you might want to hurry up if you absolutely have to have this stealthy little watch.
