The Apple Watch Series 7 is the wristwatch from the business, and it costs $399. It has a larger Retina display that is constantly on, a more rounded design with a larger case, improved durability, and faster charging. The Watch Series 7 is the most recent Apple Watch in the company’s lineup, having been released in September 2021. It’s still early in the process of being released. Apple launches new Apple Watch models every September, and there’s no reason to think that a new Apple Watch Series 8 won’t be released this year.
Apple Watch Series 8 models are expected to arrive in less than a year, with a number of enhancements and improvements. This implies that the Apple Watch Series 7 is still an excellent investment, but some customers may opt to wait until the Apple Watch Series 8 is released.
While the Apple Watch Series 7 is Apple’s most feature-rich, high-end wristwatch, for those who prefer capabilities like blood oxygen monitoring, ECG, an always-on display, and more premium finishes, the Apple Watch SE is a more inexpensive option. The Apple Watch SE, which starts at $279, has many of the same capabilities as the Apple Watch, such as an optical heart rate sensor and fall detection, but at a reduced price that strikes a mix between usefulness and cost.
If pricing is your primary issue and you do not want advanced health functions, the $199 Apple Watch Series 3 may be a better fit than the $399 Apple Watch Series 7. It includes many of the Apple Watch’s basic capabilities. Because it is an older model, the Apple Watch Series 3 has various drawbacks, including a smaller display, an older chipset, and the absence of a compass, fall detection, ECG, and blood oxygen monitoring.
Design
The Apple Watch Series 7 maintains the rounded, square form of prior generations, but now comes in two casing sizes: 41mm and 45mm, to accommodate different preferences and wrist sizes. The Apple Watch Series 7 features a redesigned appearance with softer, more rounded edges. Despite the fact that the casings have grown in size, they still work with bands from prior generations.
The stainless steel Apple Watch models are the heaviest, weighing 32 kilos to 51.5 grams depending on size and casing material. This represents a modest weight gain over the previous generation. Series 7 is the same thickness as Series 6 at 10.7mm.
All Apple Watch Series 7 versions include a black ceramic and crystal back with four LED clusters and four photodiodes for health-monitoring functions like heart rate tracking, blood oxygen monitoring, and ECGs.
The Apple Watch contains a Digital Crown for scrolling and navigation on the side, as well as a Side Button for bringing up frequently used apps, activating emergency services, confirming Apple Pay purchases, and more.
The Digital Crown includes haptic feedback that provides a precise, mechanical sensation while scrolling through menus and operating other aspects of the Apple Watch, and it’s especially important for the ECG app because it contains a built-in electrode that works in tandem with the rear sensors.
The appearance of the Digital Crown varies based on the Apple Watch model you purchase. The red ring around the Digital Crown on LTE models indicates that they have LTE capability, whereas the red ring is absent on GPS-only models.
Materials and Colors
The Apple Watch Series 7 comes in three different materials: aluminum, stainless steel, and titanium. Aluminum Apple Watches are the least expensive, while titanium Apple Watches are the most expensive.
This year, Apple released four new aluminum colors: Midnight, Starlight, Green, and Blue. These are in addition to the (PRODUCT)RED shade from Series 6. The stainless steel Apple Watch models come in three colors: Silver, Gold, and Graphite, with a dark grey tint. Titanium versions come in two colors: natural (grey silver) and Space Black.
The aluminum Apple Watch variants are built from 100 percent recycled 7000 series aluminum, are lightweight and affordable and are designed for an active lifestyle, whereas the stainless steel Apple Watch models are heavier, more expensive, and are designed for everyday wear rather than exercise.
The titanium Apple Watch models have the same durability as the stainless steel ones and have a brushed appearance, but they are lighter and stain-resistant. Titanium variants have a darker, more matte surface than stainless steel models.
The sapphire crystal displays on the stainless steel and titanium variants are more scratch-resistant than the Ion-X glass on the aluminum models. The aluminum variants come with and without LTE, however, the stainless steel and titanium models are LTE-only, with no cheaper GPS models available.
The titanium variants are lighter than the stainless steel models, which are the heaviest of the Apple Watch models, and all of the Series 7 models are up to 10% heavier than the Series 6 models in terms of weight.
Durability
The Apple Watch Series 7 has a new front crystal component that is tougher and has a more robust shape. It’s more than 50% thicker and more resistant to cracking than prior models.
Ion-X glass protects the display on aluminum Apple Watch models, while sapphire crystal glass. It protects the display on stainless steel and titanium Apple Watch models. Because sapphire crystal glass is a stronger material than Ion-X glass, it offers better scratch resistance. As a result, sapphire crystal models are more resistant to scratching and everyday use.
The Series 7 is also dust-resistant to IP6X, making it ideal for use in harsh locations like the beach or the desert.
The device still has WR50 water resistance, which means it can be submerged in water up to 50 meters deep thanks to seals and adhesives. The only port of entry is the speaker, which requires air to make sound and has been designed to expel water through sound vibrations after being exposed to moisture.
The Apple Watch can be worn when swimming in the ocean or in a pool because it is water-resistant to 50 meters. It’s only good for shallow-water activities; it won’t work for scuba diving, waterskiing, showering, or any other activity that requires high-velocity water or deep submersion.
Water damage is not covered by Apple’s Apple Watch warranty, so use caution when exposing the device to water.
Display that is always on
The displays on the Apple Watch Series 7 are bigger, with about 20% more screen space. The boundaries have been reduced to just 1.7mm, which is 40% smaller than the borders on Apple Watch Series 6. The new display is curved so that it bends slightly over the glass’s top edges.
The Apple Watch Series 7 has an OLED ultra low power temperature poly-silicon and oxide display (LTPO). To enable Always-On functionality, which allows the watch to face, complications. And other information to be continuously visible with the screen not going black when the Apple Watch is not in use. Just like the Apple Watch Series 5 and Series 6.
When the wrist is down, the display dims to save battery life, but critical aspects like the watch hands stay illuminated at all times. Touching the watch face or elevating the wrist returns the display to full brightness, and Apple has tuned watch faces for the feature to save battery waste. The display’s refresh rate drops from 60Hz to as low as 1Hz while the Apple Watch is not in use.
Indoors, the Always-On Retina display is up to 70% brighter than the Apple Watch Series 6 display. Allowing you to see the watch’s face without having to raise your wrist. Alternatively, the display can be activated while the wearer’s wrist is down
Chip S7
The Apple Watch Series 7’s dual-core S7 System in Package (SiP) is built on the Apple Watch Series 6’s S6 processor and offers similar performance. Apple did not mention any speed bumps, and it’s expected to have the same processing power as the S6 CPU from the prior generation.
Health Benefits
The Apple Watch Series 7 has the same health-tracking features as the Apple Watch Series 6. A second-generation optical heart rate sensor calculates metrics including calorie burn. Resting heart rate, and an abnormally high heart rate. While an electrical heart rate sensor can be used to take electrocardiograms. And blood oxygen monitoring is enabled by LEDs and infrared light. Other key health-related capabilities, such as fall detection, are enabled by a built-in accelerometer and gyroscope.
The Apple Watch can detect a low heart rate, a high heart rate, and irregular heart rate. As well as monitor for health issues such as atrial fibrillation and provide warnings when abnormalities are discovered.
Monitoring of Blood Oxygen
The blood oxygen monitoring capability offered in the Apple Watch Series 7 is enabled. Via the sensors on the rear of the Apple Watch. When blood oxygen saturation falls below 95 to 100 percent in a healthy person. It can indicate a serious health problem that requires quick attention.
Photodiodes measure the quantity of light reflected back from the green, and red. And infrared LEDs that shine light onto the blood vessels in the wrist. The color of the blood is then calculated by Apple’s algorithms. Which indicates how much oxygen is present.
The Apple Watch determines blood oxygen levels by looking at bright red blood, which is fully oxygenated. Vs darker blood, which contains less oxygen. The Series 7 can monitor blood oxygen levels between 70 and 100 percent, much like the Series 6.
ECGs
The Apple Watch’s backside electrodes and the Digital Crown work together to allow users to capture single-lead electrocardiograms, just like the Apple Watch Series 4. A doctor can use an ECG to diagnose health problems by measuring the electrical activity of the heart.
Holding a finger on the Apple Watch’s Digital Crown captures an ECG, which can detect a sinus rhythm (normal). An aberrant result, or an ambiguous result that should be communicated with a doctor. At heart rates of more than 100 beats per minute, the ECG can diagnose atrial fibrillation.
Charging and Battery
The Apple Watch Series 7 has an “all-day” battery life of 18 hours on a single charge. The 45mm Apple Watch Series 7 has a 1.189Wh (309 mAh) battery within, according to early teardowns. The 1.17Wh battery in the 44mm Series 6 is up 1.6 percent. The 41mm Apple Watch Series 7’s 1.094Wh battery has increased by 6.8%. From the previous-generation 40mm device’s a 1.024Wh battery.
Because of Apple’s Magnetic Fast Charger USB-C Cable and a new charging architecture. The Apple Watch Series 6 can now charge 33% faster than the previous model. Thanks to a power adapter rated at 18W or above. A single eight-minute charge can provide up to eight hours of sleep tracking. Customers will need to supply a 20W or higher power adapter to get rapid charging with the Apple Watch Series 7. It comes with a Magnetic Rapid Charger USB-C Cable. Fast chargers from third parties are now available as well.
Apple uses 90-time checks and 90 notifications to compute “all-day” battery life. 45 minutes of app activity followed by a 60-minute workout while listening to music through Bluetooth. For LTE versions, Apple expects a four-hour LTE connection and a 14-hour iPhone connection. In certain situations, such as during calls or workouts, the Apple Watch will drain faster.
What is the future of the Apple Watch?
The Apple Watch Series 8 may include additional health capabilities such as temperature tracking. For fertility, sleep apnea diagnosis, and improved activity tracking. But don’t expect any major new health sensors. It could possibly have Apple’s new flat-edged design, which was first rumored for the Series 7. As well as a car collision detection technology that would alert emergency services if you were involved in an accident.
Apple is working on a “rugged” version for sports, hikers. And others who use the Apple Watch in more harsh environments and want a more robust gadget. As well as a new Apple Watch SE.
