While most wearables pair with your smartphone, the Neptune Duo goes the opposite route: all the computing power is contained in the smartwatch — known as the Neptune Hub — which pairs with a dummy 5-inch display called the Neptune Pocket.
The Hub is full Android Lollipop smartphone, featuring a curved non-flexible display, quad-core processor and 64GB of storage. There are also a speaker and microphone, plus 4G, Wi-Fi, GPS, Bluetooth 4.0 and NFC for easy pairing with accessories. Conveniently, the Pocket screen doubles as a battery juice pack for the Hub, recharging it when it needs more power. With a combined capacity of 3,800 mAh, the Neptune Duo can last a few days of normal usage on a single charge. Pre-order the device here.
