The original Apple Watch from 2015.

The Apple Watch, which started as a tech/fashion accessory and evolved into a health and fitness devices, is the world’s most popular smartwatch. It can handle a wide variety of the iPhone’s most popular functions — alerts, phone calls, playing music, etc. — and also track a user’s heart rate, sleep patterns and other health-related metrics.

It is an “incredibly accurate timepiece, an intimate and immediate communication device and a groundbreaking health and fitness companion,” Apple said at the product’s launch.

Here’s a guide to the Apple Watch and its uses.

Apple Watch unveiling and key features

Apple CEO Tim Cook unveiled the original Apple Watch on September 9, 2014, calling it “the most personal device we’ve ever created.” But then the company made anxious consumers wait seven months for the first Apple Watch’s launch on April 24, 2015. With fancy showcases and a $17,000 gold model (called Apple Watch Edition), Apple focused on fashion.

From the very beginning, Apple Watch straps came in a wide variety of colors and were constructed from an array of materials. Plus, they were easily interchangeable, so someone could, for instance, wear a comfortable silicone Apple Watch band during a sweaty gym session, then switch to something much more luxurious for a dinner date.

Additionally, users can customize watch faces, manage notifications and install apps tailored to their preferences, using Apple’s Watch app on the iPhone.

Like the iPhone, the Apple Watch utilizes a touchscreen for most interactions. Apple Watch owners also can use Siri voice commands.

Digital Crown and Taptic Engine

The Apple Watch also introduced several innovative features that set it apart from traditional timepieces. The Digital Crown, a small knob on the side of the watch that doubles as a push button, lets users scroll, zoom and interact with the interface without obstructing the display. The Taptic Engine provides subtle haptic feedback, notifying users of incoming notifications or providing prompts during workouts.

When the Apple Watch was released on April 24, 2015, it was met with both excitement and skepticism. Critics questioned its utility and wondered if it would become a niche gadget. However, consumers quickly embraced its sleek design, customizable interface, and array of features.

Apple Watch is fully integrated with other Apple devices, particularly the iPhone (which is required to use the smartwatch). Apple Watch can, for instance, be used to unlock a Mac. This seamless integration with the Apple ecosystem helped solidify the device’s place in the market. It quickly became the bestselling smartwatch in the world.

watchOS: The Apple Watch operating system

Just as the iPhone runs on iOS, the Apple Watch runs on watchOS. Apple upgrades the operating system every year, adding features exclusive to new devices as well some for older models. New versions of watchOS typically add new Apple Watch faces as well.

watchOS 1 powered the original Apple Watch. It included nearly two dozen stock apps, including Activity, Alarm, Calendar, Camera Remote, Mail, Maps, Messages, Music, Passbook (which will become Wallet in later versions), Phone, Photos, Remote, Settings, Siri, Stocks, Stopwatch, Timer, Weather, Workout and World Clock.

Key additions over the years include:

  • Home App, Scribble, Emergency SOS and the Breath app (watchOS 3).
  • Redesigned Music and Workout apps (watchOS 4).
  • Podcasts app and Walk-Talkie (watchOS 5).
  • Cycle Tracking, Noise, Calculator and Voice Memos apps, plus a new App Store for Apple Watch apps (watchOS 6).
  • Blood Oxygen app for Apple Watch Series 6 models, Activity app renamed to Fitness, plus new Memoji app and automatic handwashing detection (watchOS 7).
  • Crash Detection and Ovulation apps for Apple Watch Series 8 models (watchOS 9).
  • Double tap gesture for Apple Watch Series 9 and Apple Watch Ultra 2 (watchOS 10).

Apple Watch models

Apple Watch (1st generation)

Released on April 24, 2015, the original Apple Watch came in three models: the entry-level Apple Watch Sport with an aluminum body, the “regular” Apple Watch with a stainless steel casing and the Apple Watch Edition with a gold body, which cost $10,000-plus. All came with a built-in heart rate sensor powered by infrared and visible-light LEDs and photodiodes.

Apple’s first wearable introduced the Digital Crown and the Taptic Engine for subtle taps on the wearer’s wrist. It ran apps and allowed notifications, and offered health- and fitness-tracking capabilities. It allowed customization through Apple Watch faces and a variety of Apple Watch bands. However, the underpowered single-core S1 chip in the first-gen Apple Watch led to laggy performance.

Sizes: 38mm and 42mm

Apple Watch Series 1 and Series 2

Both released on September 16, 2016, these second-gen Apple Watch models benefited from upgraded processors that improved performance. The Series 1 ran on the Apple S1P, a variant of the dual-core Apple S2 chip with the processor’s GPS capability removed. It also added water resistance for swimming.

Apple Watch Series 2 ran on the Apple S2 with GPS enabled for for tracking outdoor workouts. It came with a brighter display and water resistance up to 50 meters. An Apple Watch Series 2 Edition model came with a white ceramic case.

Sizes: 38mm and 42mm

Apple Watch Series 3

Unveiled on September 22, 2017, Apple Watch Series 3 ran on a dual-core Apple S3 chip and came with an altimeter for tracking elevation. A variant with LTE cellular connectivity via an innovative eSIM allowed calls and streaming of Apple Music tracks and podcasts.

Sizes: 38mm and 42mm

Apple Watch Series 4

Announced on September 21, 2018, Apple Watch Series 4 brought the smartwatch’s first big redesign. Thinner bezels meant a bigger display, and the overall design was streamlined. The display was also much brighter than previous models. A new sensor worked with the ECG app to enable electrocardiograms. (Apple received clearance from the U.S. Food and Drug Administration for the watch’s ECG feature.)

With Apple’s S4 chip, a 64-bit dual-core processor, Series 4 also gained a performance boost. The smartwatch’s improved accelerometer and gyroscope boosted fitness tracking. And a new fall-detection feature could automatically call emergency features if the wearer suffered a fall.

Sizes: 40mm and 44mm

Apple Watch Series 5

Unveiled on September 10, 2019, during Apple’s “By Innovation Only” event, the Apple Watch Series 5 was the first model to feature an always-on Retina display. Clever animations allowed apps to “activate” when the watch was lifted, conserving battery power when the watch was lowered. A more energy-efficient Apple S5 chip brought better performance. And a built-in compass appealed to the outdoors crowd. Apple also added an International Emergency Calling feature for cellular models.

Apple Watch Series 5 Edition models arrived in three case options: ceramic and two titanium finishes (natural and space black).

Apple Watch Series 6

Released on September 15, 2020, during Apple’s “Time Flies” event, the Apple Watch Series 6 added a new sensor capable of monitoring the wearer’s blood oxygen saturation (SpO2). Coming at the peak of the COVID-19 pandemic, it was a perfect health-related feature.

The Apple S6 chip brought increased performance, while the Apple U1 chip enabled support for ultra-wideband technology for short-range communication with other compatible devices. The always-on display was 2.5 times brighter than the one in Series 5. Apple Watch Series 6 also added an always-on altimeter, 5 GHz Wi-Fi support and faster charging.

Sizes: 40mm and 44mm

Apple Watch SE

A budget model also released on September 18, 2020, the first-gen Apple Watch SE ran on the Series 5’s S5 chip. It lacked key features such as an always-on display, ECG and blood oxygen sensors, and support for ultra-wideband and 5 GHz Wi-Fi.

Sizes: 40mm and 44mm

Apple Watch Series 7

Released on October 15, 2021, Apple Watch Series 7 boasted a larger, more durable display with even thinner bezels. It added faster charging, slightly longer battery life and anIP6X dust-resistance rating.

Sizes: 41mm and 45mm

Apple Watch Series 8

Announced at Apple’s Far Out event on September 7, 2022, Apple Watch Series 8 added a new temperature sensor to power women’s health features like cycle tracking and ovulation estimates. It runs on a faster Apple SP8 chip and also adds more precise accelerometers, and a new Crash Detection feature that can call authorities after a car or motorcycle accident.

Sizes: 41mm and 45mm

Apple Watch Ultra

Also announced at the Far Out event, Apple Watch Ultra is a beefier model aimed at endurance athletes. A larger titanium case (49mm) with a flat front crystal makes it look more like a rugged sports watch. A brighter display proves better for outdoor activities.

A new Action button, which can trigger a specified app or function with a single touch, makes it easier to use in certain situations (like when wearing ski gloves or underwater). Integrated multi-band GPS, a water temperature sensor and a built-in siren also appeal to outdoor adventurers.

Size: 49mm

Apple Watch SE (second generation)

The final of three smartwatches unveiled at the Far Out event, the second-gen Apple Watch SE also runs on the SP8 chip and offers Crash Detection thanks to advanced accelerometers. However, the updated budget model does not feature an always-on display, a temperature sensor or ECG capabilities.

Sizes: 40mm and 44mm

Apple Watch Series 9

Announced at Apple’s “Wonderlust” event on September 12, 2023, the Apple Watch Series 9 runs on a more-efficient Apple S9 chip with a faster GPU and Neural Engine that enable on-device Siri. The main addition is a new “double tap” gesture: When the wearer taps a thumb and forefinger together, it’s as if they tapped the watch’s touchscreen. Series 9 also added a second-generation UWB chip for increased range and precision.

Sizes: 41mm and 45mm

Apple Watch Ultra 2

Also unveiled at the Wonderlust event, the Apple Watch Ultra 2 packs an even brighter display (up to 3,000 nits) as well as the new S9 chip for on-device Siri. The design remains the same, as do many of the rugged watch’s capabilities.

Size: 49mm

Let’s roll up our sleeves and take a closer look at what’s in store for Apple Watch.

A tiny new silicon micro-speaker could transform future wearables — like Apple Watch and other smartwatches — by dramatically reducing thickness while improving audio quality, xMEMS Labs said Tuesday. It unveiled Sycamore-W, an ultra-thin micro speaker engineered for wrist-worn devices. It could make more room in devices as new features like AI interactions become more prevalent.

“Sycamore-W redefines audio for smart watches, combining compact design with robust performance to meet the demands of next-generation wearables,” said Mike Housholder, xMEMS VP of Marketing and Business Development. “As the wrist becomes a key interface for ears-free, hands-free AI interactions, Sycamore-W empowers manufacturers to deliver premium audio in smaller, lighter more durable devices.”

The Apple Watch Translate app can help you quickly speak in a different language while you’re abroad, right from your wrist. Translate between 20 different languages by speaking out loud, play translations out of your Apple Watch speaker and build a list of favorite phrases you can play instantly.

Apple Translate doesn’t support as many languages as the more popular Google Translate — but Google doesn’t have an app for the Apple Watch. The fastest and most convenient way to speak another language from your wrist is with Apple’s app.

May 2: Today in Apple history: First Apple watch is a freebie for upgraders May 2, 1995: Apple enters the wearables space with its first watch. However, the first Apple watch is a timepiece with no fitness-tracking tech, no on-screen notifications and a whole lot of 1990s styling.

The device comes two decades before wearables actually will become a thing. A regular wristwatch, the freebie gadget is available via a special mail-in offer to Mac OS upgraders.

You can manually add a workout to Apple Fitness+ if you need to log some exercise while you weren’t wearing your Apple Watch. Maybe your watch ran out of battery at the start of your run, or maybe you simply forgot to turn it on. By adding a missing workout, you can give yourself credit for the exercise you did.

This power could be used for evil as well as good. You could, hypothetically, say you ran a three-hour marathon every day last week. But you would only be fooling yourself.

For the 10th anniversary of its launch, we compiled over a decade of Apple Watch history into a quick timeline. Starting with the original three collections — including models in solid 18 karat gold — all the way to today’s far more advanced (and sensible) Apple Watch Series 10 and Ultra 2.

The Apple Watch was the first major product introduction of Tim Cook’s reign as Apple CEO. There was immense pressure on Apple to prove that it could still innovate without Steve Jobs. While the Apple Watch wasn’t as flashy as the iPhone and iPad, it’s grown into an incredible business rife with breakthrough technology, in one of the most physically constrained form factors yet.

Closing your three Apple Watch Activity rings can become such an obsession that it’s easy to forget why you’re doing it. But what does it really mean to close an Apple Watch ring? The Stand ring seems obvious. We all know we shouldn’t sit around on our asses all day. But how about the Move and Exercise rings, which sound so similar?

Actually, no. The Apple Watch’s Move and Exercise rings are very different, and understanding that difference is massively important if you want to achieve your fitness goals.

In a harrowing incident off the coast of Australia, an experienced swimmer’s routine morning body surfing session turned potentially deadly after riptides took him out to sea.

Update: Apple Australia’s YouTube channel posted a new video Thursday, below, dramatizing Shearman’s rescue. It recreates his desperate SOS call, his struggles amid huge swells and the dramatic relief when the rescue helicopter appears overhead. The video only lasts a minute, but by the end, with music swelling, it might bring you to tears.

Apple and the National Hockey League forged a partnership that puts Apple Watch at the center of game officiating, according to reports Friday. The collaboration introduced a custom-built NHL Watch Comms app designed specifically to assist on-ice officials during games, and it will see its first outdoor use Saturday.

“We wanted to make sure that the officials had really good awareness and were able to keep their eyes on play,” explains Andres de Corral, vice president of digital services at Presidio, the technology firm that developed the app. “So by enabling haptic responses, we were able to provide non-visual cues to the officials.”

You won’t lose this remote

You can use your iPhone (or even your Apple Watch!) as a remote for your Apple TV. It’s a convenient feature when you’ve lost the remote in the couch cushions. (You can use your iPhone to help find it as well.)

Even if your remote’s not gone missing, sometimes it’s sitting on the table way over there and you don’t want to interrupt a show by asking for someone to pass it to you. Or maybe, someone is intentionally hogging the remote and you want to pause the video yourself. Either way, it’s really easy to do from an iPhone or an Apple Watch.
