The Apple Watch Series 8, which had been available since 2015, was unveiled in September 2022 and followed the Apple Watch Series 7, which had been open since 2015.
The Apple Watch Series 8 maintains its predecessors’ design language and feature set. The display, slim bezel, sapphire back, and Digital Crown with haptic feedback are all consistent between the 41mm and 45mm casings.
Apple has kept and expanded its current health tracking features, including monitoring of the heart rate, blood oxygen levels, ECG Readings, sleep patterns, falls, and loud noises. A woman’s temperature might be a helpful indicator of her overall health.
All Apple Watches with Cellular or GPS connectivity will have international roaming enabled by the fall.
Both aluminum and stainless steel are available for the Series 8 Apple Watch. Aluminum is available in Starlight, Midnight, Silver, and RED, while stainless steel comes in Silver, Graphite, and Gold. Apple’s approved bands from the past are compatible with the Series 8, as are the new hues.
Mechanical Watch Design
There are no noticeable cosmetic changes to the Series 8 Apple Watch. It was introduced in 2021 and is similar to its forebears in that it is a rounded square shape.
The Apple Watch may weigh anything from 32 to 51.5 grams, depending on the size and material of the casing, and its display has rounded corners. The Apple Watch Series 8 is the heaviest model since it is constructed of stainless steel.
All Apple Watch Series 8 versions include a black ceramic and crystal back that houses four LED clusters and four photodiodes for use with various health monitoring capabilities such as heart rate monitoring, blood oxygen monitoring, and electrocardiograms.
The Apple Watch has a digital crown for scrolling and navigating and a side button for accessing apps, making phone calls, and more.
The ECG app extensively uses the Digital Crown, which has an electrode that, in conjunction with the rear sensors and haptic feedback, gives a precise, mechanical sensation while navigating menus and adjusting other Apple Watch settings.
The look of the Digital Crown on your Apple Watch might be different from one model to the next. The Digital Crown on the LTE-capable eyes has a red ring to distinguish between watches that allow LTE data transfer and those that support GPS.
Fabrics and Designs
Apple’s latest wristwatch, the Series 8, comes in aluminum and stainless steel. Regarding Apple Watches, the aluminum models are an excellent choice for people on a tighter budget than the stainless steel models.
The metal comes in various colors: black, starlight blue, silver, and (PRODUCT)RED. Stainless steel comes in multiple colors, including gold, graphite, and space black.
Apple Watches made from the 7000 series of recyclable aluminum are slim, reasonably priced, and ideal for an active lifestyle. Stainless steel Apple Watches are bulkier, costlier, and designed for regular wear.
41mm
- Thirty-two grams of aluminum weight.
- 3 grams, or 42.3% of the total weight, is the mass of the stainless steel item.
45 mm
- Weight: 38.8 grams of aluminum
- Durable and lightweight (51.5 grams) stainless steel
Durability
Series 8 Apple Watch face crystals are strengthened like Series 7 devices. Aluminum Apple Watches use Ion-X glass, whereas steel and titanium versions use sapphire.
All Apple Watch Series 8 models are waterproof to 50 meters (WR50 requirements) and dustproof to IP6X standards, making them suitable for sandy or dry areas.
The speaker is the only source of water entry, designed to expel moisture through sound vibrations aggressively.
The Apple Watch is 50-meter water-resistant so you can swim with it.
It’s best for calm, shallow seas, not deep submersion or high-speed water sports like scuba diving or waterskiing. Apple Watch Ultra is ideal for these activities.
Since Apple’s warranty does not cover water damage, you mustn’t immerse your Apple Watch in liquid.
Influencing Elements on Health
A third-generation optical heart rate sensor, an electrical heart rate sensor that can record electrocardiograms, and LEDs and infrared light that can detect blood oxygen levels are all included in the Series 8 Apple Watch. The accelerometer and gyroscope inside the gadget allow for other critical health-related features, such as fall detection.
If the Apple Watch detects a low, high, or irregular heart rate, it can alert the user to potential health problems, including atrial fibrillation.
- Assessment of Blood Oxygenation Levels
Using sensors on its back, the Apple Watch Series 8 can track blood oxygen levels. Once oxygen saturation drops below 95% in a healthy person, prompt medical attention may be necessary.
- ECGs
With the Apple Watch’s Digital Crown and the electrodes on the back, it’s feasible to do a single-lead ECG. To diagnose a patient, a physician might assess the heart’s electrical activity using an electrocardiogram.
The Apple Watch is a single-lead electrocardiogram (ECG) device, requiring only two contact points to provide accurate readings. Apple Watch ECGs may only take 30 seconds to complete, no matter where you are, but a doctor-performed electrocardiogram with six to twelve leads will deliver more accurate findings.
- Tracking How People Sleep
Series 8 Apple Watch may measure sleep patterns while worn overnight. It monitors waking and sleep cycles and estimates light, deep, and REM sleep. You can learn how often and for how long you awaken during the night by maintaining a sleep journal.
Identification of Accidents
Apple Watch Series 8 devices may now detect a vehicle collision and send an emergency alert thanks to upgraded motion sensors and a sensor-fusion algorithm. Apple Watch will automatically dial 911 if the user does not reply within 10 seconds of an accident being detected. Additionally, it will send an emergency alert to the people you choose.
Checking the Temperature
One sensor scans the wearer’s wrist, and the other examines ambient air temperature. Apple Watch Series 8 may also help users track reproductive cycles by predicting ovulation timings.
Apple says its temperature sensor might help women better anticipate their periods.
Time Of Use For A Battery
Series 8 Apple Watches have an 18-hour “all-day” battery life, which may be improved to 36 hours with watchOS 9’s Low Power Mode.
Apple boasts its gadgets can last “all day” on a single charge using criteria like 90 checks, 90 alerts, 45 minutes of app engagement, and 60 minutes of Bluetooth exercise music. Apple estimates an LTE iPhone will have a connection for four hours and access for 14 hours. If you call or exercise while wearing an Apple Watch, the battery may deplete faster.
Connectivity
Series 8 Apple Watches come in GPS-only and GPS + Cellular models, both powered by Apple’s W3 CPU. Unlike the GPS-only models, the GPS + Cellular models can connect to LTE networks without needing an iPhone.
With LTE, Apple Watches may also connect to the internet without needing to be in the range of an iPhone or a preexisting Wi-Fi network. However, Apple Watches has included an LTE connection, beginning with the Series 3 model.
U1 Chip
Apple Watch Series 8 includes the U1 processor, an Ultra Wideband technology first seen in the iPhone 11 series. Apple says the U1 chip’s accurate short-range wireless makes previously impossible experiences feasible. Car Keys is one such app that may be used in place of a physical car key on an Apple Watch or iPhone.
Emergency Alert
Series 5 was the first to have a global Emergency SOS button due to an LTE connection. Emergency SOS may be used regardless of where you bought your Apple Watch or your cellular subscription.
Let’s imagine a user has fall detection activated on their Apple Watch, which detects that they’ve fallen and are unresponsive. It will trigger a worldwide distress signal. Holding the Apple Watch’s side button activates the SOS feature, informing local emergency services if you’re injured overseas.
The World Wide Web Protocol, Bluetooth, and the Global Positioning System
Apple Watch Series 8 supports Bluetooth 5.0 and Wi-Fi 802.11a/b/g/n (both 2.4 GHz and 5 GHz). Bluetooth 5.0 improves range, speed, broadcast message capacity, and compatibility over Bluetooth 4.2.
Series 8 devices, whether LTE or not, all have a GPS chip that allows the Apple Watch to determine its location without needing an iPhone. The Apple Watch Series 2 introduced this function.
