First Generation Apple Watch Specs and Hardware

The First-Generation Apple Watch
Apple Inc.

Introduced: Sept. 9, 2014
Available: April 24, 2015
Discontinued: n/a

The first-generation Apple Watch marks a major expansion of Apple's product line. While previous devices had largely extended Apple's core strength in computing—after all, the iPhone is essentially a pocket-sized computer, and the iPad is roughly a smaller, portable laptop—the Apple Watch represents the first time Apple has brought computing and the Internet to a non-digital, non-office-focused device.

Some of the major features of the Apple Watch includes its support for Healthkit, Apple's health-data platform that allows compatible apps to collect user data and share it with healthcare providers. The Apple Watch monitors health data at a level of detail previously unavailable in a single consumer device—including heart rate, fitness activity, and much more—thanks to a series of sensors built into the device.

Apple isn't the first company to introduce a smartwatch; earlier competitors had been released on the Android platform (such as the Samsung Galaxy Gear) and from startups like Pebble. This strategy is consistent with Apple's approach to the MP3 player and smartphone markets: don't introduce the first product; wait to learn what will make the product great and introduce the best option.

In order for the Apple Watch to work completely, it must be used with an iPhone. The watch uses the GPS, Bluetooth, and Wi-Fi features built into the iPhone to provide those services.

Some features of the Watch can work without a phone, but it's not completely clear what those are at this point.

The Watch requires iOS 8.2 and higher, which comes with an Apple Watch app used to configure the Watch and install apps.

    In the announcement, Apple CEO Tim Cook referenced many other features of the Watch, including control of in-home devices (perhaps via HomeKit), control of cars via apps, and much more.

    These features will depend on third-party app developers and hardware makers to release products that support them.

    User Interface

    • Touchscreen—The Apple Watch sports an iPhone-style touchscreen for interacting with some onscreen content.
    • Digital Crown—The side button on the phone is used to control aspects of the user interface such as zooming, scrolling through lists, and returning to the home screen. It is the major user interface control on the Watch.
