New 'iPhone 6c' and second-gen Apple Watch set for March announcement

The first-gen Apple Watch, released earlier on this year, has certainly helped to bring the idea of wrist-worn tech to the forefront. It hasn't quite had the disruptive impact of the original iPhone or iPad, nor has it apparently affected the thriving market for fitness trackers. But it's an emerging product that Cupertino intends to proceed with, beginning with the second model in a few months' time. Per a new report, Apple will unveil the second-generation Apple Watch in March, and take the wraps off a 4-inch 'iPhone 6c' at the same event.
Apple has been working on a number of Watch-centric features, including a camera, wireless functionality, a tracker for sleep, and some new health sensors. Whether all of these enhancements will be ready to roll with the next version is not yet established. But if the upcoming device is to really grasp the smartwatch nettle, one suspects that a camera, at the very least, will need to be part of the bargain.
There's no word on the design characteristics of this elusive handset, although we did hear earlier this month that a metallic iPhone 6c could be ready for a February launch. A March unveiling alongside the next Apple Watch would make some degree of sense, although given that iPhones tend to arrive in the fall, it would be an uncharacteristic launch period for an Apple handset.
