The Apple Watch Series 3 models looked identical to the Apple Watch models before them (original, Series 1, and Series 2), were available in the same sizes (38 mm and 42 mm), but were more powerful. The Series 3 had a faster processor, GPS, a barometric altimeter, and Siri support. This Apple Watch Series 3 is a Space Gray, 42 mm model.
The Series 3 Apple watch was the first to offer cellular service as an option, although this model is the GPS-only version. Apple described the Series 3 Watch in a press release:
“The third-generation Apple Watch is an amazing health and fitness companion with intelligent coaching features, water resistance 50 meters and a new barometric altimeter that measures relative elevation. Apple Watch Series 3 comes in two models, one with GPS and cellular, and one with GPS, both featuring a 70 percent faster dual-core processor and new wireless chip.”
This Apple Watch had a 312×390 OLED screen with Ion-X glass and a 7000 series anodized aluminum housing. Apple estimated the battery life at “up to 18 hours.”
The Apple Watch Series 3 used Apple’s S3 processor, “which allows for quicker app launch times and smoother graphics, and, for the first time, enables Siri to speak using the built-in speaker.” It also included a new W2 wireless chip that made Wi-Fi 85% faster and Bluetooth and Wi-Fi 50% more power efficient. The watch shipped with watchOS 4.
The Apple Watch SE Generation 2 was released along side of the Apple Watch Series 8 on September 7, 2022, and was described by Apple: “The redesigned Apple Watch SE delivers the core Apple Watch experience at a new starting price.” Apple positioned the SE Generation 2 as:
“…a great way for users to start their Apple Watch journey, use with Family Setup, or gift to their loved ones. Powerful upgrades include the S8 SiP advanced dual-core processor, the same processor that is in Apple Watch Series 8 and Apple Watch Ultra, making it 20 percent faster than the previous generation, along with Crash Detection and international roaming.”
Notably, the Apple Watch SE Generation 2 used a back case made of a nylon composite material that made the Watch lighter, but arguably decreased the durability offered by the ceramic backs of the other models. While the Series 8 case sizes of the time increased to 45 mm and 41 mm, the Apple Watch SE Generation 2 remained at 44 mm and 40 mm.
While the Series 8 used an Always-on Retina display, the SE Generation 2 retained a Retina display that showed only when you looked at your wrist. Although the SE Generation 2 lacked the ability to run the ECG app, it had many of the same features of the Series 8 and even used the same S8 processor. The Vitals app on the SE Generation 2 included heart rate, respiratory rate, and sleep duration, but lacked wrist temperature and blood oxygen sensors. The SE Generation 2 included Emergency SOS, international emergency calling, fall detection, crash detection, water resistance up to 50 m, Siri, Find My, and the same 18-hour battery life ast the Series 8.
The Apple Watch SE Generation 2 (GPS) was available only in Aluminum and in three colors, Midnight, Starlight, and Silver. The 44 mm size measured 44 mm x 38 mm x 10.7 mm and weighed 32.9 g; while the 40 mm size measured 40 mm x 34 mm x 10.7 mm and weighed 26.4 g. The screen sizes were 368 x 448 pixels (977 square mm display area) for the 44 mm option and 324 x 394 pixels (759 square mm display area) for the 40 mm option.
This Apple Watch SE Generation 2 example is a silver GPS model and shipped with a Winter Blue Sport Band.
Although the Apple Watch Series 10 was the most significant update to the Apple Watch to date, the design changes were not radical, and the new features were more aptly described as evolutionary—not revolutionary. That being said, the Series 10 was arguably the most elegant Apple Watch design so far. Apple described the Series 10 in a press release:
“The world’s bestselling watch is thinner than ever, featuring the biggest, most advanced display yet; sleep apnea notifications; faster charging; and water depth and temperature sensing.”
The most striking features of the Series 10 included the display and its relative thinness. The display was 46 mm (with a 42 mm option also available), and was reported to be up to 40% brighter when viewed at an angle. Compared to the Series 9, the size was just 1 mm larger, but notably, the larger Series 10 model was just 3 mm smaller than the Apple Watch Ultra (49 mm), and the smaller option at 42 mm was the same size as the larger option of the original Apple Watch (Series 0). At the same time, the 46 mm Series 10 had a larger screen—416 x 496 pixels, 1220 square mm display area—than the 49 mm Apple Watch Ultra 2—410 x 502 pixels, 1185 square mm display area. The Series 9, by contrast was 396 x 484 pixels with a 1143 square mm display area.
The thinness of the Series 10 was noticeable, even though it was only 1 mm thinner overall. The 45 mm Series 9 was 10.7 mm thick, while the 46 mm Series 10 is 9.7 mm; however, the Series 10 rounded-rectangle case was thinner with thickness of the round sensor accounting for the measurement. The Apple Watch Series 10 was also 2.3 grams lighter than the Series 9 (46 mm aluminum GPS model).
Regarding finishes, the Series 10 dropped the Stainless Steel option and replaced it with a lighter Titanium option in three colors: slate, gold, and natural titanium. The Aluminum models included the classic silver color, brought back a rose gold option, and introduced a new “Jet Black Aluminum” option that matched the previous glossy sheen of the black stainless steel models at a nearly $400 lower cost and reduced weight.
The Series 10 added some water features similar to the Apple Watch Ultra line, including a water temperature sensor; a depth gauge and app; and support for the Oceanic+ app for snorkeling.
The Series 10 added two new audio-related features. First, the new media playback feature added an enhanced speaker so users could listen to music and podcasts directly through the speaker on the Watch. Second, a new microphone added voice isolation for using the speakerphone and voice recording features.
Finally, I would like to note that the first generation (sometimes called the Series 0) of the Apple Watch was released nearly 10 years before the Series 10 (April 24, 2015), and the Series 10 will likely be the “current” available model at the 10-year mark. Thus, the Series 10 can represent 10-year anniversary of the product line. Since Apple offers an easy way to compare their different Watch models, here are some highlights to show how far the Apple Watch has come in nearly 10 years:
Size—Original: 42 mm and 38 mm; Series 10: 46 mm and 42 mm (the smallest available option now matches the size of the largest original Apple Watch)
Screen brightness—Original: 450 nits; Series 10: 2000 nits (Series 10 is over 300% brighter than the original Apple Watch)
Heart health notifications—Original: High/low heart rate notifications; Series 10: High/low heart rate notifications, ECG, Low cardio fitness notifications
Water resistance—Original: Splash resistant; Series 10: Water resistant to 50 m, depth gauge to 6 m, water temperature sensor
Battery—Original: Up to 18 hours; Series 10: Up to 36 hours in low-power mode (twice the battery life)
Finishes—Original: Aluminum, Stainless Steel, 18K Gold; Series 10: Aluminum, Titanium (the $10,000 and $12,000 Edition models were dropped after the original “Series 0” Watch)
Weight—Original: 42 mm 30 g; Series 10: 46 mm 36.4 g (Series 10 is 21% heavier)
Thickness—Original: 42 mm 10.5 mm; Series 10: 46 mm 9.7 mm (Series 10 is 8% thinner)
Screen size—Original: 42 mm 312 x 390 pixels, 740 square mm; Series 10: 46 mm 416 x 496 pixels, 1220 square mm (the Series 10 screen is 65% larger)
Number features—Original: 13 features; Series 10: 36 features (although this metric is subjective, many of the features listed by Apple include multiple points)
The iPhone 14 Pro was announced on September 7, 2022; began pre-orders on Friday, September 9, 2022; and was available beginning Friday, September 16, 2022. Apple’s website led with the following description of the iPhone 14 Pro:
“A magical new way to interact with iPhone. Groundbreaking safety features designed to save lives. An innovative 48MP camera for mind-blowing detail. All powered by the ultimate smartphone chip.”
The primary new technologies used in the iPhone 14 Pro included: “Always-On display, the first-ever 48MP camera on iPhone, Crash Detection, Emergency SOS via satellite, and an innovative new way to receive notifications and activities with the Dynamic Island.”
The four colors available at release were deep purple, silver, gold, and space black. The iPhone 14 Pro had a 6.1-inch “Super Retina XDR display with ProMotion” with an Always-On display (for the first time on an iPhone) that used a 1Hz refresh rate with power-efficient technologies. In practice, the Always-On display faded to a dim/dark version of the Wallpaper and allowed the time and up to four widgets to show (a widget above the time and up to 3 below the time). Other “Live Activities” showed in the bottom two-thirds of the Lock screen, including alerts and play/pause options for media.
The iPhone 14 Pro also delivered “the highest outdoor peak brightness in a smartphone: up to 2000 nits, which is twice as bright as iPhone 13 Pro.”
The Dynamic Island was also introduced in the iPhone 14 Pro. The design of this iPhone removed the “notch” that had been used since the iPhone X and moved the functions slightly lower into a pill shape. Apple described the Dynamic Island system as one “that blends the line between hardware and software, adapting in real time to show important alerts, notifications, and activities. With the introduction of the Dynamic Island, the TrueDepth camera has been redesigned to take up less of the display area.”
Apple continued, “Without impeding content on the screen, the Dynamic Island maintains an active state to allow users easier access to controls with a simple tap-and-hold. Ongoing background activities like Maps, Music, or a timer remain visible and interactive, and third-party apps in iOS 16 that provide information like sports scores and ride-sharing with Live Activities can take advantage of the Dynamic Island.”
The iPhone 14 Pro camera system added a 2x camera (in addition to the 0.5x, 1x, and 3x options on the iPhone 13 Pro). The iPhone 14 Pro also offered a new “48MP Main camera with a quad-pixel sensor that adapts to the photo being captured, and features second-generation sensor-shift optical image stabilization.”
Other new camera features included a front TrueDepth camera with an ƒ/1.9 aperture for better low-light photos and video, adaptive True Tone flash with an array of nine LEDs, and Action mode for “incredibly smooth-looking video that adjusts to significant shakes, motion, and vibrations, even when video is being captured.”
All iPhone 14 models added Crash Detection that used a variety of built-in sensors (dual-core accelerometer, gyroscope, barometer, GPS, and microphone) to “detect a severe car crash and automatically dial emergency services when a user is unconscious or unable to reach their iPhone.” Additionally, Emergency SOS via satellite was added, “which combines custom components…to allow antennas to connect directly to a satellite, enabling messaging with emergency services when outside of cellular or Wi-Fi coverage.”
The iPhone 14 Pro models are powered by the A16 Bionic chip that includes two high-performance cores and four high-efficiency cores, an accelerated 5-core GPU with 50% more memory bandwidth, and a new 16-core Neural Engine capable of nearly 17 trillion operations per second.
Many of the new features of the iPhone 14 Pro were enabled by iOS 16, released along with the entire iPhone 14 line.
The Apple Watch Series 5 looked similar to the Series 4, but had an “Always-On” Retina display “that never sleeps,” a faster processor, and more storage. The GPS model required an iPhone tether to use the phone features (higher-end models had built-in wireless cellular). This watch added international emergency calling that allowed calling “emergency services directly from Apple Watch in over 150 countries, even without iPhone nearby.”
Like all previous Apple Watch models, the Apple Watch Series 5 uses a Digital Crown and a touch display. The screen is OLED at 368×448 with haptic feedback and a Force Touch display. New health and fitness features with Series 5 included Cycle Tracking, the Noise app and Activity Trends.
Previous Apple Watch models used screens that went black to conserve power. The Always-On screen in the Series 5 was made possible by the OLED display and other hardware and software. According to Apple:
“Each watch face has been carefully optimized for the new display and to preserve battery life, the screen intelligently dims when a user’s wrist is down and returns to full brightness with a raise or a tap. Several advanced technologies work together to deliver this new feature, including the industry’s only low-temperature polysilicon and oxide display (LTPO), ultra-low power display driver, efficient power management integrated circuit and new ambient light sensor.”
Three different aluminum options were available: Space Gray with Black Sport Band (this model), Silver with White Sport Band, and Gold with Pink Sand Sport Band. Many other combinations were available by customizing the watch online. The Series 5 introduced the “Apple Watch Studio,” both on the Apple website and on the Apple Store app. The Apple Watch Studio allowed the opportunity for buyers to select a “preferred case and band combination to create a look that is uniquely their own.”
New materials were also offered with the Series 5, including natural titanium and space black titanium. Aluminum cases in silver, gold, and space gray were offered in “100 percent recycled 7000 series aluminum.” Stainless steel cases were unchanged and were offered in gold, silver, and space black.
The Black Unity Apple Watch was Apple’s first “limited-edition Apple Watch Series 6” and was described as being part of a collection including the watch, the Black Unity Sport Band, and a Unity watch face.
Apple described the Black Unity Watch: “Inspired by the colors of the Pan‑African flag, the Black Unity Collection celebrates a symbol that unites people across the African Diaspora. Apple supports organizations dedicated to advancing racial equity and justice.”
The Apple Watch Series 6 was nearly identical to the Series 5 models, but the Series 6 added some new internal features: faster chip, a new Blood Oxygen sensor (SpO2), and an altimeter that was always on. Like all previous Apple Watch models, the Apple Watch Series 6 uses a Digital Crown and a touch display. The screen is OLED at 368×448.
On Apple’s product page dedicated to the Black Unity Apple Watch, detailed information was provided about the design and symbolism behind the watch:
“Designed by Black creatives and allies throughout Apple to celebrate and acknowledge Black history and culture, the Black Unity Sport Band is inspired by the colors of the Pan-African flag and pays homage to the rich tradition and craft of quilt-making. Three individual pieces of colored fluoroelastomer are assembled by hand and compression-molded as one. Complemented by the dynamic Unity watch face, which displays an ever-changing pattern of irregular shapes as Apple Watch moves, these colors are brought together in a unique tapestry. The innovative pin-and-tuck closure is laser-etched with ‘Truth. Power. Solidarity.'”
Like Apple’s (PRODUCT)RED efforts to provide charitable donations in support of HIV/AIDS and COVID-19, Apple took this opportunity to show support for organizations dedicated to advancing racial equity and justice:
Black Lives Matter Support Fund via the Tides Foundation—The Black Lives Matter movement fuels campaigns for justice, combats and counters acts of violence, and creates space for Black imagination and innovation.
European Network Against Racism (ENAR)—ENAR, a pan-European anti-racism network, is the voice of the anti-racist movement in Europe.
International Institute on Race, Equality and Human Rights—The institute works to protect the human rights of marginalized and vulnerable people who suffer from discrimination.
Leadership Conference Education Fund—The Leadership Conference Education Fund promotes and protects civil and human rights and builds public education campaigns that empower and mobilize advocates around the United States.
NAACP Legal Defense and Educational Fund, Inc. (LDF)—LDF seeks structural changes to expand democracy, eliminate disparities, and achieve racial justice to fulfill the promise of equality for all Americans.
Souls Grown Deep—The partnership is dedicated to promoting the work of African American artists and supporting their communities by fostering economic empowerment, racial and social justice, and educational advancement.
The Apple Watch Series 6 was nearly identical to the Series 5 models, but the Series 6 added some new internal features: faster chip, a new Blood Oxygen sensor (SpO2), and an altimeter that was always on. Externally, the Apple Watch Series 6 was available in colors including blue aluminum and (PRODUCT)RED aluminum, in addition to aluminum in space gray, gold, and silver; stainless steel in graphite, silver, and gold; and titanium and titanium space black.
This 44mm Apple Watch Series 6 is an aluminum (PRODUCT)RED model that shipped with a (PRODUCT)RED Sport Loop. This model has GPS capability, but it lacks the cellular capability of higher-end options.
Like all previous Apple Watch models, the Apple Watch Series 6 uses a Digital Crown and a touch display. The screen is OLED at 368×448.
When purchased online at the Apple Store, the aluminum Apple Watch Series 6 models were available in four additional color combinations: Blue Apple Watch with Deep Navy Sport Band; Gold Apple Watch with Pink Sand Sport Band; Silver Apple Watch with White Sport Band; and Space Gray Apple Watch with Black Sport Band.
Along with the Apple Watch Series 6, two new band designs were released including the Apple Solo Loop, a soft and stretchable “liquid silicone” loop band with no mechanical closure; and an Apple Braided Solo Loop, a loop band made from stretchable, silicone-infused thread with no mechanical closure. Both the new loops were sold in sizes.
The Apple Watch Series 2 models were called “the ultimate device for a healthy life” and added “incredible fitness and health capabilities including a water resistance 50 meter rating for swimming, and built-in GPS so users can now run without an iPhone.” The announcement for the Apple Watch Series 2 was made on September 7, 2016, approximately one year after the announcement of the original Apple Watch.
Apple Watch Series 2 models included a dual core processor, water resistance to 50 meters, and built-in GPS. This Apple Watch Series 2 model is a the Nike+ version in the 42 mm size and featured a 312×390 display with an anodized aluminum case.
The Apple Watch Series 2 Nike+ configurations had a custom Nike+ fluroelastomer band with compression-molded perforations—also known as holes—that reduced weight and improved ventilation. The Nike+ models included custom Nike-branded watch faces. There originally were four Apple Watch Nike+ configurations:
silver aluminum case with silver/volt (neon yellow) Nike sport band
silver aluminum case with silver/white Nike sport band
space gray aluminum case with black/volt (neon yellow) Nike sport band
space gray aluminum case with black/cool gray Nike sport band
This Apple Watch was purchased with the silver/volt band. In this photo, the band has been replaced with a midnight blue leather loop.
The Apple Watch Series 4 was the first major redesign of the Apple Watch family and added several important functions, including health-related features. The display was over 30% larger and filled the entire screen with curved corners, it added more advanced input capabilities, more powerful processing, and more advanced sensors. This model also included GPS and cellular service for use in the United States and Canada.
Like all cellular-capable Apple Watch Series 4 models, this watch could connect to the Internet without an iPhone and send and receive phone calls with an activated cellular service. It was controlled with a Digital Crown with haptic feedback and Force Touch.
This Apple Watch Series 4 model is 44 mm (previous Apple Watch models were 38 mm and 42 mm) with a 368×448 OLED screen. This stainless steel case model used a sapphire crystal to cover the display. All Series 4 models used a ceramic and sapphire crystal back to connect to the wireless charger.
The Apple Watch Series 4 shipped with “revolutionary health capabilities, including a new accelerometer and gyroscope, which are able to detect hard falls, and an electrical heart rate sensor that can take an electrocardiogram (ECG) using the new ECG app.” When announced on September 12, 2018, the ECG feature was not available until it was released on December 6, 2018, through an iOS update.
The ECG feature on Apple Watch Series 4 marked “the first direct-to-consumer product that enables customers to take an electrocardiogram right from their wrist, capturing heart rhythm in a moment when they experience symptoms like a rapid or skipped heart beat and helping to provide critical data to physicians. The irregular rhythm notification feature on Apple Watch can now also occasionally check heart rhythms in the background and send a notification if an irregular heart rhythm that appears to be atrial fibrillation (AFib) is identified.”
In addition, a new accelerometer and gyroscope could detect falls and automatically call 911.
There were 12 different options for this particular Apple Watch Series 4 model:
silver aluminum case with white Sport Band
silver aluminum case with seashell (gray) Sport Loop
gold aluminum case with Pink Sand Sport Band
gold aluminum case with Pink Sand Sport Loop
space gray aluminum case with black Sport Band
space gray aluminum case with black Sport Loop
silver stainless steel case with white Sport Band (this Apple Watch)
silver stainless steel case with silver Milanese loop
space black stainless steel case with black Sport Band
space black stainless steel case with black Milanese loop
The Apple Watch Series 3 models had a faster processor and added GPS, a barometric altimeter, and Siri support. This Apple Watch Series 3 is a Nike+ 42 mm model that included GPS and cellular capabilities in United States/Canada, allowing it to send and receive phone calls and access the Internet without an iPhone. This was the first Apple Watch series with this capability. The cellular Apple Watch Series 3 models added a red dot to the Digital Crown.
This Apple Watch had a 312×390 OLED screen and included exclusive Nike watch faces, a built-in Nike+ Run Club app, and audio guided runs featuring the voice of a Nike+ Run Club coach.
Four different options were available for this specific Apple Watch Series 3 Nike+ cellular model:
silver aluminum case with Pure Platinum/Black Nike Sport Band
space gray aluminum case with Anthracite/Black Nike Sport Band
silver aluminum case with Bright Crimson/Black Nike Sport Band
space gray aluminum case with a Black/Pure Platinum Nike Sport Loop
This Watch is the silver aluminum case with Bright Crimson/Black Nike Sport Band.
