In fact according to Chinese website Commercial Times (via 9to5Mac), they have suggested that Quanta is expected to kick off the trial production of the Apple Watch 2 this month. While we can’t say with certainty when the wearable will be launched, a trial production this month does seem to indicate that a launch by June would certainly be possible.
Apple is expected to hold an event in the earlier part of the year which is usually reserved for their Mac computers, so perhaps we could learn more about the device then. No word on what we can expect from the Apple Watch 2, but some wishlists have indicated that better battery life would be nice.
We have also heard the reports that Apple has been ramping up hires in the health sector that could be going towards adding more health features to the Apple Watch, so perhaps new fitness or health-related sensors could be a nice touch as well. In any case until we hear from Apple officially, take it with a grain of salt for now.
