and other Apple products and services.
Apple Watch relies on a wirelessly connected
to perform many of its default functions such as calling and texting. However, Wi-Fi chips in all Apple Watch models allow the smartwatch to have limited connectivity features away from the phone anywhere a Wi-Fi network is available. Series 3 LTE Apple Watches are able to be used without needing to be consistently connected to an iPhone, though an iPhone is still required to set up the device. Most Apple Watches that are currently produced requir the Series 3 LTE model requires an
or later with iOS 11.
The Apple Watch was released on April 24, 2015 and quickly became the best-selling wearable device with 4.2 million sold in the second quarter of the 2015 fiscal year.
The second generation of Apple Watches were released in two tiers in September 2016: the Apple Watch Series 1 and , while the first generation was discontinued.
was released on September 22, 2017 alongside the discontinuation of the Apple Watch Series 2. Apple still produces the second-generation Series 1 Apple Watch as an entry-level device.
The goal of the Apple Watch was to enhance the uses of an iPhone while also providing the user with some additional new features.
was hired by Apple to make wearable technology for the wrist. He said: "People are carrying their phones with them and looking at the screen so much. People want that level of engagement. But how do we provide it in a way that's a little more human, a little more in the moment when you’re with somebody?" Apple's development process was held very much under wraps until a
article revealed how some internal design decisions were made.
Rumors surrounded an Apple-developed wearable device back as far as 2011, which conceptualized the device as a variation of the
that would curve around the user's wrist, and feature
integration. On February 10, 2013, both
reported that Apple was beginning to develop an -based smartwatch with a curved display. On February 12, 2013,
reported that Apple's smartwatch project was "beyond the experimentation phase in its development", and had a team of at least 100 designers working on the project. Further reports in March 2013 indicated that Apple planned to release the device by the end of the year.
In July 2013,
reported that Apple had begun hiring more employees to work on the smartwatch, and that it was targeting a possible retail release in late 2014.
In April 2014, Apple CEO
that the company was planning to launch new product categories that year, but did not reveal any specifics. In June 2014,
reported that production was expected to begin in July for a release in October.
On September 9, 2014, during a press event where the
was also presented, the new product was introduced by
as "the next chapter in Apple's story" with a video that focused on its design and the various combinations of bands and case styles that would be available to the consumers. After the reveal video, the auditorium was filled with prolonged applause and a standing ovation as Tim Cook reappeared onstage wearing an Apple Watch. Cook explained that Apple Watch was "a precise timepiece, a new intimate way to communicate from your wrist, and a comprehensive health and fitness device."
In comparison to other Apple products and competing smartwatches, marketing of Apple Watch focused more on advertis a 12-page advertising spread for Apple Watch in an issue of
focused primarily on the different combinations of body and band styles available, and downplayed the technological aspects of it. Apple later focused upon its health and fitness-oriented features, competing against dedicated , and with watchOS 3, expanded on them with fitness tracking for wheelchair users, social sharing in the Activity app, and a Breathe app to encourage mindfulness.
Pre-orders for the Apple Watch began on April 10, 2015, with the official release on April 24.
The device was not branded as "iWatch" (which would put it in line with its pre-existing product lines such as iPod, iPhone, and ) due to
conflicts in in the United States, the "iWatch" trademark is owned by OMG Electronics – who was
a device under the same name, and is owned in the
by Irish firm Probendi. In July 2015, Probendi sued Apple Inc. for , arguing that through
on the , it caused advertising for the Apple Watch to appear on search results pages when users searched for the trademarked term "iWatch".
Initially, the Apple Watch was not available at the . Beginning on April 10, 2015, customers could make appointments for demonstrations and fitting, but the device was not in-stock for walk-in purchases and had to be reserved and ordered online.
felt that this distribution model was designed to prevent Apple Store locations from having long line-ups due to the high demand. Selected Apple Watch models were available in limited quantities at luxury boutiques and authorized Apple resellers. On June 4, 2015, Apple announced that it did plan to stock Apple Watch models at its retail locations. On August 24, 2015,
announced that it would begin stocking Apple Watch at its retail stores by the end of September. Both
also announced plans to offer Apple Watch through its retail stores.
On September 9, 2015, Apple launched a new subset of Apple Watch in collaboration with . This collection, dubbed "Apple Watch Hermès," comes in a stainless steel body with crafted leather bands in distinctive styles from Hermès. The following year, Apple launched another subset of Apple Watches in collaboration with
dubbed "Apple Watch Nike+". Both subsets feature additional watch faces and bands exclusive to their branding, but otherwise function exactly like standard Apple Watches of their series.
Apple Watch went on sale in
on November 6, 2015. The device has also launched in Chile, the Philippines,
Indonesia, and South Africa.

The Apple Watch is available in multiple variants, distinguished by different combinations of casing and interchangeable bands. The watch is available in two sizes: 38 mm (1.5 in) and 42 mm (1.7 in). The design of the watch has not changed significantly since its release, so customizable bands and accessories are typically compatible with any Apple Watch of the associating size. The casing of the watch includes a mechanism to enable the straps to be interchangeable. For input, the watch includes a "digital ", which can be turned to scroll or zoom and pressed to return to the home screen, and a
that features
technology, which makes it pressure-sensitive and capable of distinguishing between a tap and a press. The watch also has a side button which can be used to display favorite contacts and access Apple Pay. Apple rates the device's battery for 18 hours of mixed usage. Apple Watch is charged by means of , using a cable similar to the
cable from Apple's
of laptops. If the watch's battery depletes to less than 10 percent, the user is alerted and offered to enable a "power reserve" mode, which allows the user to continue to read the time for an additional 72 hours. The watch then reverts to its original mode when recharged.
Apple did not explicitly market the first generation Apple Watch as being , stating that it can withstand splashes of water (such as rain and hand washing), but does not recommend submersion (). However, external testing by
and others revealed that Apple Watch can function when submerged in various conditions (such as swimming), although its touchscreen experiences "erratic" behavior when submerged.
Apple introduced a high level of water resistance with the release of the Apple Watch Series 2, and the device was explicitly advertised as being suitable for swimming and surfing.
The first-generation Apple Watch uses the single-core
. It does not have a built-in
chip, instead relying on a paired iPhone for location services. It uses a
called the "Taptic Engine" to provide
when an alert or a notification is received, and is used for other purposes by certain apps. The watch is equipped with a built-in , which uses both
and visible-light
and . All versions of the first-generation Apple Watch have 8  the operating system allows the user to store up to 2 GB of music and 75  of photos. When the Apple Watch is paired with an iPhone, all music on that iPhone is also available to be controlled and accessed from the Apple Watch.
The second generation has two tiers. The Series 1 has a variant of the
processor with GPS removed known as the . It has a lower starting price than first generation watches. The Series 2 has the dual-core
processor, water resistance to 50 meters, a display twice as bright, and a GPS receiver.
The third generation of the Apple Watch features a faster processor, the dual-core ,
vs 4.0 on older models, a built-in altimeter for measuring flights of stairs climbed, increased RAM size, and is available in a variant with
cellular connectivity. Siri is able to speak on Apple Watch Series 3 due to the increased processing speed of the Watch. The Series 3 Apple Watch is explicitly not compatible with
devices, requiring users to have an
or later for the GPS-only model, or an
or later for the cellular-enabled model.
Apple Watch runs , whose interface is based around a home screen with circular app icons. The OS can be navigated using the touchscreen or the crown on the side of the watch. During its debut, the first generation Apple Watch needed to be paired with an
or lat this version of iOS introduced the Apple Watch app, which is used to advertise Apple Watch, pairing with an iPhone, customize settings and loaded apps, and highlight compatible apps from the App Store.
The Apple Watch is capable of receiving notifications, messages, and phone calls via a paired iPhone. "Glances" allowed users to swipe between pages containing
dis however, this feature was replaced by a new Control Center. watchOS also supports
to send content from Apple Watch to an iOS or macOS device, and act as a
for an iPhone camera,
is also available for voice commands, and is capable of responding with voice prompts on the Series 3 watches. Apple Watch also supports , and enables its use with older iPhone models that do not contain
(NFC) support.
Apple Watch's default apps are designed to interact with their iOS counterparts, such as , Phone, Calendar, , , Music, , Reminders, Remote (which can control
and ), Stocks, and . Using the Activity and Workout apps, a user can track their physical activity and send data back to the iPhone for use in its Health app and other -enabled software. With watchOS 3, Reminders, Home, Find My Friends, Heart Rate, and Breathe were added to the many stock apps.
With the release of watchOS 4 and the Series 3 Apple Watch, iPhone 5 support was dropped, requiring users to use an
or later with iOS 11 to use watchOS 4. Apple Watches still running watchOS 3 or below remain compatible with the iPhone 5. Further, the upcoming watchOS 5 will not support the first Generation (prior to Series 1) Apple Watch.
watchOS 1.0.1 featured performance improvements and support for additional
and languages, and was released on May 29, 2015. At
2015, Tim Cook announced watchOS 2.0; described by
as a "significant revamp", it included a new
that allows more direct access to the device's hardware, new watch faces, the ability to reply to an e-mail, and other features. watchOS 2.0 was set to be released on September 16, 2015, but was delayed due to a bug fix taking
it was instead released on September 21, 2015.
watchOS 2.0 featured new features and more general improvements to Apple Watch. Following the software update, some users experienced issues with lag.
watchOS 3.0 was announced at WWDC 2016, with a priority on performance. Users are able to keep apps running in memory as well as receive background updates and refreshed information. Other updates include a new Dock invoked with the side button to replace the performance-laden Glances, an updated Control Center, and new reply options on Messages. Several new watch faces have also been added, including , along with the ability to switch watch faces from the lock screen simply by swiping. A new feature called SOS allows users to hold the dock button to make a call to the local emergency line and pull up the user's Medical ID. Another feature is Activity Sharing, which allows sharing of workouts with friends and even sending their heartbeats to one another. A new app called Breathe guides users through breathing exercises throughout the day, with visuals and haptic feedback. watchOS 3.0 was released to developers on June 13, 2016 and was made available to the public on September 13, 2016.
watchOS 3.1 was released to the public on October 24, and watchOS 3.2 was released near the end of March, 2017. Both updates added minor improvements and bug fixes.
watchOS 4.0 was announced at WWDC 2017 on June 5, 2017, and released to the public on September 19. watchOS 4 features a proactive Siri watch face, personalized activity coaching, and an entirely redesigned music app. It also introduces GymKit, a technology platform to connect workouts with cardio equipment.
watchOS 4.3 was released on 29 March 2018. It introduced support for Nightstand mode in portrait orientation. It brought back the ability for music playing on the iPhone to be controlled using the Music app on the Apple Watch and also enabled control of playback and volume on Apple’s HomePod. Other new features included a new charging animation and a new app loading animation. Activity data was added to the Siri watch face, and the battery complication more accurately reports battery life.
watchOS supports third- a
app runs in the background on the iPhone as an application extension while a set of native user interface resources are installed on Apple Watch.[] Thus, watchOS apps must be bundled within their respective iOS app, and are synced to the watch either manually, or automatically upon installation of the phone app.
Starting June 1, 2016, the only new watch apps allowed on the App Store will be those developed with the watchOS 2 (or later) SDK; no third-party languages or SDKs can be used to develop apps.

An Apple Store opens its doors on the first day of sales of the Apple Watch.
Following the announcement, initial impressions from technology and watch industry o the watch was praised by some for its "design, potential capabilities and eventual usefulness", while others offered criticism of these same aspects. Venture capitalist
said he "can't wait" to try it, and ' biographer
described it as "extremely cool" and an example of future technology that is "much more embedded into our lives". However, Evan Dashevsky of
said it offered nothing new in terms of functionality compared to the , except the customizable vibration notifications. In November 2014, Apple Watch was listed by Time as one of the 25 Best Inventions of 2014.
Initial reviews for the device have been generally positive with some caveats. Reviewers praised the watch's potential ability to integrate into everyday life and the overall design of the product, but noted issues of speed and price. Many reviewers described the watch as functional and convenient, while also noting failure to offer as much potential functionality as preceding smartphones. Farhad Manjoo of
mentioned the device's steep learning curve, stating it took him "three long, often confusing and frustrating days" to become accustomed to it. Some reviewers also compared it to competing products, such as
devices, and claimed "The Smartwatch Finally Makes Sense". Reviewers had mixed opinions on battery life though, with Geoffrey Fowler of
saying "the battery lives up to its all-day billing, but sometimes just barely," and others compared it to the , which "strolls through three days of moderate usage." Tim Bradshaw of the
used several applications over a period of days. He concluded that there is no "killer application" so far besides telling the time, which is the basic function of a wristwatch anyhow.
When using the Apple Watch, some users have reported issues using the heart monitoring feature due to permanent skin conditions including . The Watch uses photoplethysmography technology (PPG) which utilizes the green LED lights to measure heart rates. To gauge a user's heart rate, the watch flashes green light from the LEDs at the skin and records the amount of this light that is absorbed by the red pigment of the blood. However, under certain circumstances the skin may not allow for the light absorption to be read properly and thus provide inaccurate results.
Some users have complained that the logo and text on the back of the Apple Watch Sport model, primarily the space gray version, can be easily worn off.
The first generation Apple Watch Edition, where 18 k gold models retailed from US$10,000 to US$17,000, received a lukewarm reception as the Apple brand "hasn't established its value yet in gold" compared to similar-priced timepieces from
and .[] These Swiss luxury manufacturers were known for their "products' intricate craftsmanship [that] justifies that high price tag". An analyst suggested "What makes a high-end watch? It's the Swiss movements, the inner workings. That's why collectors buy them. This [Apple Watch Edition] has none of that. It's inserting a high-end case on a piece of electronics" which was not endlessly upgradable and would become obsolete in a couple years like other tech gadgets. In addition, Apple Retail Stores that carry the Apple Watch Edition would be "totally antithetical to their current retail model", according to the Jewelers' Security Alliance, since "You can't have people touching it. You can't have it out on counters. You have the same problems that retail jewelers have, in terms of distraction thefts, in terms of switching, in terms of grab and runs". The second-generation Apple Watch Edition is made of ceramic and sold for a much lower retail cost of US$1,249.
Financial analysts offered early sales estimates from a few million to as many as 34.7 million in the first year. 's
summarized the breadth of reactions, writing that "there is not enough information yet to determine how this product will fare when it finally reaches the market next year".
Owing to the inadequacy of materials, the Apple Watch's delivery was delayed from its initial pre-order release date of April 10, 2015. As a result, only 22 percent of the pre-ordered Apple Watches were dispatched in the United States during the weekend after the release date. It is estimated Apple received almost one million Apple Watch pre-orders in the United States during the initial six hours of the pre-order period on April 10, 2015, after which it sold out and further orders would start delivering in June. A report later on by an analyst stated that Apple Watch was already a $10 billion business during its first year.
Apple has not disclosed any sales figures of for the Apple Watch. An estimate by IDC states Apple shipped over 12 million units in 2015. In late 2016, a veteran of the Swiss watch industry said Apple sold about 20 million watches and had a market share of about 50 percent.
