Apple Watch.

Apple Watch introduces the Digital Crown.

It’s a versatile tool that answers the fundamental challenge of how to magnify content on a small display.

With the Digital Crown, you can scroll, zoom, and navigate Apple Watch without covering the display.

The Digital Crown lets you navigate Apple Watch fluidly and precisely.

Magnify content, scroll through lists and messages, and make selections. All without obstructing the screen.

Apple Watch has a flexible Retina display. 

It's laminated to a single crystal of sapphire, the hardest transparent material after diamond.

Infrared and visible-light LEDs, along with photo sensors, detect your pulse rate. 

Working with other technologies in Apple Watch, these help provide a comprehensive picture of your daily activity.

Apple Watch is as much about self-expression as it is utility.

There are a range of watch faces and millions of ways to personalize them.

Crafted from the finest materials. 

Apple Watch is built from custom alloys of stainless steel, aluminum, and 18-karat gold. With bands as thoughtfully designed as the watch itself.

The Home screen looks familiar, but it’s a new experience designed for the Apple Watch display.

Most Apple Watch faces are extremely customizable.

You can change colors, choose design elements, and add functionality.

Receive and send messages in amazing ways — from your wrist. 

Send preset phrases, smart responses based on your conversation, audio messages, your location — even interactive emojis.

You’ll know this town like the back of your hand.

With Maps, Apple Watch can show your current location, turn-by-turn directions, and how long it will take to get to your destination.

With Apple Watch, you can share something as personal as the beating of your heart.

Press two fingers on the screen to capture and send your heartbeat.

Kevin Lynch introduces WatchKit.

It gives developers all the tools they need to extend their apps to Apple Watch.

Apple Watch comes with two apps that give a complete picture of your health and fitness.

The Activity app monitors movement throughout the day. The Workout app tracks dedicated workouts.

Apple Watch measures three aspects of movement.

The Activity app shows three rings: one for Move, one for Exercise, and one for Stand.

The Workout app shows real-time stats such as calories, time, distance, and pace for your workouts.

Set goals, chart your progress, and earn awards as you track specific workouts, such as running, walking, and cycling.

The Apple Watch will be available ‘early 2015′ for $349
