Reports: Apple's iWatch Coming This October

Apple will be launching its much-rumored iWatch this October, according to multiple reports out today, and the company is so confident in the device that it’s reportedly looking to produce three to five million units per month.

Apple’s shares took a small dip after the company’s WWDC keynote last Monday, in part because investors had hoped for bigger hints about what could be the company’s next blockbuster device. Instead Apple announced new software platforms that allowed its devices to talk more easily to one another when in close proximity — a feature it called Continuity — along with an app that aggregates biometric data, called HealthKit.

Both features appeared to set the scene for a wearable device, and expectations are high after Apple's Eddy Cue recently said that later in 2014, "we’ve got the best product pipeline that I’ve seen in my 25 years at Apple.”  Apple will reportedly hold a special event in October in which it reveals a wearable device that works with its HealthKit service.

Other companies in the wearable tech space believe that Apple will set a high standard with its first foray into wearables, particularly in its ability to crack the design and fashion problem that besets the current, plastic-black-band generation of fitness trackers.

Apple could for example, create mens and women’s styles for its iWatch. It might also allow users to customize the device with straps of different styles, says Ben Isaacson, founder of Connected Designs, a company that's working on women's jewelry that syncs with smartphones.

Nikkei also reports that Apple will integrate a curved OLED screen into its iWatch. OLED technology can be thinner, brighter and more power efficient than other display technologies, according to Darice Liu of OLED-tech and materials company  Universal Display Corporation. It could also be "a major factor in helping manufacturers go from early curved displays to fully flexible electronics," she added.

Apple's first wearable  device will show messages sent by smartphones as well as health-related data, according to Nikkei. Among the health data that the watch will reportedly collect: calorie consumption, sleep data, blood oxygen levels and blood glucose levels.

That last data point - blood glucose levels - could be a big win for Apple if true. Such sensors would essentially make it easier to track what a person is ingesting without relying wholly on what the wearer manually logs on their smartphone.

“Glucose tracking is the Holy Grail for wearables,” says one industry source from a large tech company also working on a wearable device. The problem is that no wearable device maker has figured out how to measure glucose non-invasively. “Nobody has cracked it yet.”
