The rumored 4-inch iPhone 6c could also be launched at the same event.
Come March 2016, Apple could be ready to make the Apple Watch 2 official, according to the folks over at 9to5Mac. The site’s sources say the second-generation watch will possibly start shipping in April, a month before the original Apple Watch went on sale. The Apple Watch 2 is expected to feature improvements to camera, wireless connectivity, sleep tracking and health sensor technology, though some of these things may or may not make it into the second Watch.
The Cupertino giant could also launch the rumored 4-inch iPhone 6c alongside the smartwatch, though this is a rumor that might or might not turn out to be accurate. Ever since Apple shifted to a 4.7-inch screen for its base iPhone model, we have heard countless rumors of the company planning on bringing back a 4-inch iPhone. But the iPhone 6 and iPhone 6S have seen great success since their announcement, so it seems unlikely Apple would waste resources on a third iPhone with a screen that would be considered rather puny in this day and age.
