Wearing an iPod Nano watch might be the coolest touchscreen watch out there. That's until you need to wash your hands and such in water. If you don't plan on ruining your little iPod Nano with some water, you'll need to take a look at the Proof watch kit brining the world's first waterproof watch band to the iPod Nano. If that wasn't enough, the Proof also adds Bluetooth functionality to the Nano so you could wirelessly stream your music. Comprised out of a IP68 graded sealed, waterproof polyurethane casing coated with silicone for use in depth of up to 3m, and a thick strap made out of flexible silicone. The Proof allows for full control of your iPod Nano's touchscreen and side buttons.

The Proof comes with three side adapter to perform different tasks. The largest of them is the Bluetooth adapter adding a considerable amount of bulk to the side of your waterproof iWatch gadget, a non-waterproof adapter will let you use your headphones while a low-profiled adapter offers complete waterproof protection, can be used when you want to wear your iWatch as a daily watch. This might not be the most appealing watch band kit for the iPod Nano we've seen before, but at least it's the first waterproof and Bluetooth enabled one.

The Proof is available to pre-order without the Bluetooth adapter on Kickstarter for $49, and $99 with a Bluetooth adapter. Both are expected to retail for $79.5 and $129.95.
