Apple launched their new Apple watch.

Apple watch is one of the best and complicated electronic devices  manufactured and released this year.Some of the important features of it are given below.The information was collected from Apple's official site.

Alarm.

 Set alarms and see how much time is remaining.

Moon Phase.

 See how much of the moon will be visible that night.

Timer.

 Set a timer right from your wrist. More than one, in fact.

Calendar.

 Get a quick look at what’s next on your schedule.

Stocks.

 Get real-time quotes for the stocks you follow most.

Weather.

 See the current temperature for anywhere in the world.

Activity.

 Monitor how active you are throughout the day.

Stopwatch.

 Start and stop anytime, directly from the watch face.

World Clock.

 Follow the time in different places around the globe.

Sunrise/Sunset.

 See when day turns into night, and vice versa.

Connect with friends.

Press the side button to access Friends, where you’ll see thumbnails of the people you like to stay in touch with most.
Tap to send a message, make a call or reach out in one of the new ways only Apple Watch makes possible.

Sketch.

Use your finger to draw something quickly.
Your friend on the other end can watch your drawing animate, then respond with a custom creation for you.

Tap.

Let friends or loved ones know you’re thinking of them with silent, gentle tap patterns they’ll feel on the wrist.
You can even customise taps for different people

Heartbeat.

When you press two fingers on the screen, the built-in heart rate sensor records and sends your heartbeat.
It’s a simple and intimate way to tell someone how you feel.

Mail is even easier to manage.

When email comes straight to your wrist, it’s more accessible and easy to manage quickly.
 You can read an email, flag it, mark it as read or unread, or delete it.

Connect with your iphone.

Apple Watch is designed for quick interactions, but sometimes you want to say more.
So we made it easy to transfer messages, calls and email from Apple Watch to iPhone,
 where you can pick up exactly where you left off. Or open it on your iPhone, where you can type a response.

Easier for call attending.

Use the built-in speaker and microphone for quick chats,
 or seamlessly transfer calls to your iPhone for longer conversations.
To mute an incoming call, just cover Apple Watch with your hand.

Send messages,emojis and voice messages.

The exciting rings.

The Activity app provides a simple visual snapshot of your daily activity, with three rings telling you everything you need to know.
The Move ring shows how many active calories you’ve burned.
The Exercise ring shows how many minutes of brisk activity you’ve completed.
And the Stand ring shows how often you’ve stood up to take a break from sitting. The goal?
Complete each ring every day.

Heart Rate Sensor.

 The custom heart rate sensor in Apple Watch detects your heart rate during workouts,
 which helps determine your intensity level, and improves the accuracy of your active calorie burn measurements.

Wi-Fi and GPS.

 Along with its accelerometer, Apple Watch uses Wi‑Fi and GPS on your iPhone to more accurately measure distance
 and speed during workouts you do outside — like walking, running and cycling.

Accelerometer.

 The Apple Watch accelerometer measures your total body movement and steps to calculate the calories you burn during the activities you do throughout the day.
 It measures all kinds of physical movement, from simply standing up to running to catch the bus to playing with your kids.

An entire computer architecture on a single chip.

Massive constraints have a way of inspiring interesting, creative solutions. A prime example is the custom-designed chip at the heart of Apple Watch.
 No traditional computer architecture could fit within such a confined space.
So we found a way to integrate many subsystems into one remarkably compact module, which is then completely encapsulated in resin to protect the electronics from the elements, impact and wear.
Configuring an entire computer system on a single chip is an industry first and represents a singular feat of engineering and miniaturisation.

Charge it overnight.

Wear it all day.
You’ll want to use Apple Watch all day long. So we gave it a battery that lasts up to 18 hours2 and made charging it at the end of the day utterly effortless.
 In fact, our goal was to make Apple Watch easy to charge in the dark.
 Without looking. While being only partially awake.
 We arrived at a solution that combines our MagSafe technology with inductive charging.
 It’s a completely sealed system free of exposed contacts.
And it’s very forgiving, requiring no precise alignment.
You simply hold the connector near the back of the watch, where magnets cause it to snap into place automatically
