The silver 18 mm band version of the Moto 360 will cost $299.99, which is the same price as the older dark or silver 23 mm metal bands. However, if you want your smartwatch to have a "champagne gold" 18 mm band, you will have to pay $30 extra as its price goes up to $329.99. Would you pay more to get a slim gold band for your Moto 360?
