The face of the watch will measure about 2.5 inches diagonally, according to Reuters, which cited a person familiar with the unannounced product. That face is expected to protrude slightly from the band and create an arch shape.
The display of the watch is expected to be a touchscreen supplied by LG Display, and Taiwan-based Quanta Computer Inc. is said to be planning to start production of the device in July.
The source also claimed that the device will include a heart rate monitor from Heptagon that will track the wearer's pulse. That aligns with rumors from over a year ago that said the device is expected to focus on biometrics for health and fitness feedback.
The so-called "iWtach" also expected to feature wireless charging -- something The New York Times also claimed earlier this year.
Apple is said to be planning a media event for this October where it's expected to introduce the company's "first wearable device," which is widely believed to be a wrist-worn connected device. The "iWatch" is believed to tap into the new HealthKit tools for developers that Apple will include in the forthcoming iOS 8 mobile operating system, which is currently available in beta for testing.
Other recent reports have suggested the device will sport a flexible OLED touchscreen. Such technology could allow Apple to introduce unique designs not possible with traditional LCD panels.
