It’s a bit difficult to bring a commondown to water. If you want to do this, a waterproof spy watch is necessary, for instance, the following integrated HD spy camera.
The new spy camera analog watch is manufactured by Thanko. The spy watch measures 100 x 47 x 23mm, weights 86g, and seems to has a fine appearance. A HD video camera has been integrated into the watch to record videos with a resolution of 640 x 480 or take photos with 1600 x 1200 resolution. Of course, the most important feature is, that the watch conforms to IPX8 waterproof standard. This means you can use the spy watch in more environments even under water beyond 1 meter. Apart from that, the watch comes with a 4GB flash memory, unfortunately only supports USB 1.1 standard.
The Thanko HD video camera spy watch is priced at about $171 USD. If you’re interested, jump to GeekStuff4U for more details, or check the following video recorded by the watch.
