Release Date: First half of 2013 (rumored) 

A number of big-name companies including Microsoft and Sony have attempted to crack the smart watch market, but none attained the success Apple did. And Apple didn't even release an actual watch. The sixth generation iPod Nano was the smallest ever iPad with a screen ever made by Apple. It had a 1.55-inch display and 24-hour battery life. And though it didn't have video playback, it became wildy popular when third-party companies dicovered it could double as a wrist watch. Thus another Apple accessory market was born.

Now that the seventh-gen iPod Nano has grown in size, rumors have sprouted up saying Apple is partnering with Intel—which is venturing the into the mobile processor market—to build a Bluetooth-enabled wrist watch that will pair with iOS devices. Chinese tech blog TGbus says the watch will come with a 1.5-inch OLED display and and may launch in the first half of 2013.
