San Francisco-based Boombotix has posted a Kickstarter page to raise funding for a new accessory for the sixth-generation iPod nano. Dubbed “The Proof,” the accessory is a watch kit for the device, made from polyurethane, coated with a thick silicone wrapping. It aims to provide IP68 waterproof coverage down to three meters by plugging all ports and allowing access to the nano’s screen via an ultra thin polycarbonate lens, and using one of three adapters, the first of which blocks access to allow for use as a watch with no audio access, and the second of which offers Bluetooth audio streaming support. A third adapter will be supplied to allow for access to the headphone jack, although it will not offer waterproof protection. Boombotix is now accepting pledges towards its funding goal of $17,000, with pledges $49 and up including the watch kit with the fully sealed adapter and headphone adapter; pledges eligible for delivery of the full kit, including the Bluetooth transmitter, begin at $99.
