Digital Crown button
Seasoned watch owners are familiar with the small rotary dial on a watch’s right side (left-handed people may flip the watch around so it’s on the left side), which is used to either wind it up (for the old-school ones anyway) or set the time. Apple Watch has one too. Called the Digital Crown button — shown in Figure 1-10 — this dial can be pressed, tapped, or turned forward or backward, with each change resulting in a different action. See Chapter 3 for more on what the Digital Crown button can do.
FIGURE 1-10: If worn on the left wrist, the side button is on the right-hand side of the watch case. The Digital Crown button is the ridged dial.
Side button
Along the side of the watch is a long button, called “side button” (how imaginative!), as shown in Figure 1-10. From the Home screen and in any app, press this button to pull up your Dock (more on this later). Press and hold the side button to use SOS; double-click to use Apple Pay; or press and hold to turn your Apple Watch on or off.
Back sensors/charger
On the back of Apple Watch, as shown in Figure 1-11, are multiple sensors to monitor your heart rate, blood-oxygen level, and more. In fact, the addition of the blood-oxygen monitoring in Apple Watch Series 6 has changed the back crystal underneath the watch; now it’s made up of four LED clusters and four photodiodes. See Chapter 2 for more on the sensors and the charger.
FIGURE 1-11: The sensors on the back of Apple Watch can, among other things, calculate your heart rate and measure your blood-oxygen percentage.
Watch band
Every wristwatch has a band to keep the screen snug on your wrist. You chose a specific band when you bought Apple Watch — whether a leather strap, a link bracelet, a classic buckle, a silicone band, or other materials and styles — but you can change bands later if you desire. Apple introduced a slew of new bands in the fall of 2020, too. It’s all about selection and customization.
Using Apple Watch’s Touchscreen
Just like you can interface with a smartphone, tablet, and laptop in different ways — based on the task at hand — Apple Watch gives you three ways to use the small screen on your wrist:
Tap: Tapping with one finger on Apple Watch performs the same function as you’d expect on a smartphone: It selects whatever you’re tapping, such as an icon to launch an app, a song to play a track, a link to a website, a photo to enlarge, or virtual buttons, such as on a calculator. On the Home screen, you tap and slide your finger around to move the icon bubbles. A tap is like a left-mouse click on a computer.
Press: Apple Watch knows the difference between a quick tap and a longer press — usually when you need to open some additional menus. Think of it as a kind of right-mouse click. For example, tapping a song plays the track, but pressing and holding it opens a set of options: Shuffle, Repeat, Source, and AirPlay. The technology that senses the difference between a tap and a press is called Force Touch.
Swipe: Many of the areas of Apple Watch — like Dock — and most of the apps you can access let you swipe left and right or up and down to navigate between different screens. For example, in Workout mode, you can see time elapsed as well as heart rate info, but swipe to the side to pull up music that you can pause and play. Swipe one more time and you’ll see some options, including the ability to lock your watch so you don’t accidentally tap the screen during rigorous exercise, to pause your counter, and so on.
Understanding Apple Watch’s Wireless Functions and Internal Sensors
Oh, Apple Watch, you cleverly hide so much of your magic under your skin.
Apple uses an integrated computer inside the Apple Watch, described as a “System in Package” — or “SiP,” for short — that includes the main processor (the main engine that drives the watch’s performance), along with memory, storage, support processors for wireless connectivity, sensors, and input/output (I/O) tech. Yes, it’s a lot of geek speak, which you don’t need to know about to use it.
Fun fact: Apple Watch Series 6’s dual-core processor is based on the same A13 Bionic chip in iPhone 11. Cool! Apple says it’s upgraded S6 SiP runs up to 20 percent faster than the previous generation, while maintaining the same all-day 18-hour battery life.
Apple Watch indeed houses a good number of wireless radios beneath its surface, including Bluetooth, Wi-Fi, GPS, NFC, and more. To better understand what they do, consider the following sections.
Bluetooth 5.0
Bluetooth makes a local wireless connection between two or more devices. Just as your wireless headset is paired with your smartphone so you can make hands-free calls, Apple Watch wirelessly communicates with a nearby iPhone. This lets you see texts on your watch, receive phone calls, control your music on your phone, and more. Bluetooth 5.0 works with devices up to 800 feet away (about 240 meters), which is significantly farther than earlier versions. If you have an Apple Watch that supports cellular connectivity and pay for the service, you can perform many of these features — calls, texts, and accessing online music — without a nearby iPhone.
