For some reason, Toyko-based USB accessory maker Thanko is selling a wide range of “spy gadgets”, with a button camera and an HD video pen as the latest additions to the line-up. Today Thanko gives us a wrist watch [JP], which may look rather unassuming from the outside but actually sports a micro spy camera.

The so-called Video Camera Analog Watch is the updated version of a spy watch that Thanko started selling in late 2008. This new model has 4GB of internal memory, which is enough to store two to three hours of video in 640×480 resolution and at 30fps.

If you have a Windows machine (XP, Vista and 7 are supported), you can transfer the material via USB as AVI files to your computer. The micro camera is placed between 1 and 2 o’clock on the dial.

The watch (weight: 115g) is already available in Thanko’s Japanese online store and costs $85. If you’re interested in getting one but live outside Japan, I suggest to contact import/export specialist (and Thanko partner) Geek Stuff 4 U.
