The iWatch wait may be almost over.

According to a Friday report by Japanese business newspaper Nikkei, Apple's first wearable tech device, which has yet to be officially announced, may be coming in October and will run iOS 8, the new mobile operating system announced at the World Wide Developers Conference last week.

Sources tell Nikkei that Apple has finalized the specs and is moving into production.

The report says that the iWatch will utilize a touchscreen OLED and could come in three different sizes, 1.3-inch, 1.5-inch and 1.7-inch. The device will sport lots of health-related sensors that will help wearers keep track of things like calorie intake, blood glucose and oxygen levels and even track their sleep.

Apple appears confident of the new product, said the report.

According to a parts manufacturer, [Apple] plans monthly commercial output of about 3 million to 5 million units, which exceeds the total global sales of watch-like devices last year.

However, a separate report from Cantor Fitzgerald analyst Brian White came out Thursday stating that the iWatch could see a September launch alongside the iPhone 6, which has also not been officially announced. Apple released its last three iPhones on the third Friday in September but waited until October or November to release updated iPad models.

With the theme around wearable technology at Computex this year, our research has uncovered more data points as it relates to Apple’s “iWatch.” Our meeting with a tech supply chain company highlighted that initial production of certain “iWatch” components is scheduled to begin later this month and there are plans for a sharp acceleration into fall.

Apple is heavily focused on health and fitness currently, releasing HealthKit, a software developers kit for the upcoming iOS 8 app Health. The app serves as a centralized place for a user's health-and-fitness sensor data.

While the iPhone 6 and iWatch have not been announced, Apple CEO Tim Cook has repeatedly hinted at a “new product category” at recent industry events.
