All you need to know about Apple Watch Series 4



While waiting for your order to appear or thinking about an upgrade, AppleInsider takes you through all the new features packed in Apple Watch Series 4.

Of all Apple's major announcements in September, "Collect Round "event, Apple Watch was without doubt the most exciting. Series 4 marks the first physical redesign of Apple Watch since it was first released.

Many Updates – Inside and Outside

  Apple Watch Series 4 Display

The biggest feature is the new, almost edge-to-edge display that gives more than 30 percent more useful real estate. Series 4 also has an updated cover that has more subtle rounded corners that fit the screen, and even manage to be a bit thinner.

If you have many bands, do not worry, all existing watches will still fit. The 38mm bands match the new 40mm size, and the older 42mm bands match 44mm.

To go with the bigger screen, Apple has revised many of the user interfaces, including updating existing look faces and including new ones. Developers may include new aspects of complications, such as to accommodate the rounded corners or larger space on the updated Infograph Modular watch face.

  Apple Watch Series 4 Digital Crown

Apple Signature Digital Crown now has a whole new mechanism of haptic feedback given when rotated, giving even greater precision. It's both 30 percent less than the last generation, while you spend 21 percent more parts.

Within the updated Digital Crown is a sensor that is also present on the back of the clock. By touching both of these electronic sensors simultaneously, the circuit completes and enables a new function – an ECG. The screen will count you down and give you the results of ECG and any possible abnormalities it detects.

  Apple Watch Series 4 ECG Heart Rate

ECG is just one of a few new cardiovascular monitoring features. Series 4 can also detect low heart rate as well as AFib. Unfortunately, some of these new features will not be available on launch, and will instead appear in a future software update.

Inside is a new second generation accelerometer with twice as dynamic range, with sampling eight times more often and capable of measuring up to 32G. Thanks to that, Apple Watch Series 4 can now detect cases. In particular, it can detect falls, ties and trips.

If a drop is detected, an alert will appear on Apple Watch. If you are ok, the notification may be rejected. Otherwise, you can notify emergency services with the clock's SOS function.

In a situation where you may not respond, Apple Watch will alert emergency services and send your position to your contingency conflict if it does not detect any movement within 60 seconds.

Other improvements include 50 percent speakers, new and rearranged microphones, a seriously fast 64-bit S4 processor, better mobile reception and Bluetooth 5.
