Taiwanese publication DigiTimes reports that Apple’s iWatch has reached the “engineering verification test” stage, which is one step below the “device verification test” stage, which is one step below production.

Based on the progress, the report claims the iWatch will be available only in 2015.

DigiTimes reports:

The sources pointed out that a product will need to first pass the PVT stage before entering to mass production, and between the EVT and PVT stages, Apple could still be change its design. [..]

[..] Currently, the upstream supply chain is mainly waiting for Apple to place component orders; however, Apple has not yet given a firm schedule for the production.

The report claims that Apple is unlikely to unveil the iWatch at the media event on September 9th, alongside iPhone 6, which contradicts reports from Re/code and Bloomberg, who have claimed Apple will unveil its wearable device next Tuesday. Re/code has also stated that while Apple is planning to unveil the iWatch next week, it may not go on sale until next year.

The highly-anticipated iWatch could feature a 1.3-inch and 1.5-inch display made out of sapphire crystal glass, and come with several sensors to track health and fitness related metrics. It is also likely to make use of iOS 8’s HealthKit health and fitness platform, and HomeKit to control connected devices.
