In 2021, Apple introduced the Apple Watch Series 7, with a lot of features that people should not miss. This came one year after  Apple decided to release Apple Watch SE - a low-cost Apple Watch option for users.

Apple Watch shoppers have many choices from the premium $399 Apple Watch Series 7 to the midrange $279 Apple Watch SE and the small budget $199 Apple Watch Series 3. As these two products have a lot of key features which include design, durability, screen, and an optical heart sensor, it is quite difficult for you to choose which one is better.

1. Design

According to Apple, Apple Watch SE have a similar design to the  Apple Watch Series 6. While Apple Watch 7’s case features a new design with softer and more rounded edges. 

With the latest version, Apple has changed the size of casings - they are also physically larger, offering 41mm and 45mm models. Because of a 1mm increase over the SE’s 40mm and 44mm casing sizes, so the Apple Watch Series 7 models are also heavier than SE models.

In addition, The Apple Watch Series 7 comes in aluminum, stainless steel, or titanium, whereas the Apple Watch SE comes in only aluminum. Apple Watches made of stainless steel or titanium have sapphire crystal displays, whereas aluminum models have Ion-X strengthened glass.

In terms of colors, the ‌Apple Watch Series 7‌ is also available in a wider variety of colors including gold, green, red, blue, black, purple, and silver.

If you are a big fan of Space Gray, Silver, or Gold aluminum Apple Watch SE, you'll have to consider which color you'd prefer for the Apple Watch Series 7. While the different color options may not influence which of the two models you would purchase as your first Apple Watch or as an upgrade from an older model, they are still an important consideration.

If you prefer stainless steel or titanium finishes, the Apple Watch Series 7 is the only model that offers these options; however, if you are satisfied with a light-weight aluminum casing and basic Silver, Space Gray, or Gold finishes, the Apple Watch SE will suffice.

2. Durability

Some expert has shown that The Apple Watch Series 7 is more robust than the SE, with a more resistant front crystal. The new crystal component has a more durable geometry and is more than 50% thicker than the one used in the Apple Watch SE.

The ‌Apple Watch Series 7‌ is more durable than the SE, espousing a more crack-resistant front crystal. The new crystal component has a more robust geometry and is over 50 percent thicker than that of the ‌Apple Watch SE‌.

The Apple Watch Series 7 is also dust-resistant, it is suitable for the environments such as beaches or deserts. Furthermore, Series 7, like the SE, is still "swim-proof," with water resistance of up to 50 meters.

While the improved durability is unlikely to be the sole motivator for Series 7 purchases, it may be an important factor for users who frequently visit dusty or sandy environments, or who have previously cracked their watch.

3. Display

Both the Apple Watch SE and Apple Watch Series 7 have similar features but the most noticeable difference is the display size. The SR has 3.0mm thick borders while the Series 7 has borders that are only 1.7mm thick.

Because of larger casing sizes, The Series 7 features larger displays with nearly 20% more screen area than the SE. 

Apple Watch Series 7 models' larger displays allow them to show more content, and Apple has optimized watchOS 8 to take advantage of the extra space with larger menu titles and buttons in apps. 

With the larger displays, Apple Watch Series 7 can have a chance to show more content, and Apple has optimized watchOs 8 to take advantage of the extra space with larger menu titles and buttons in apps. In addition, both SE and Series 7 come with a Retina LTPO OLED display and the maximum brightness of both displays is the same at 1000 nits.

The Series 7 has an always-on display as well. This means that even if you lower your wrist, the display remains on, allowing you to see your watch face without having to raise your wrist properly. While the Apple Watch SE lacks an always-on display, so users have to raise their wrist or tap the display to see their watch face.

4. Other Features

S5 - S7 CHIP

The S7 chip in the Apple Watch Series 7 is based on the same CPU as the S6 chip in the Apple Watch Series 6. Because the chips are so similar, they share the same identifier.

Apple claims that the S7 chip outperforms the S5 chip in the Apple Watch SE by 20%, allowing apps to launch up to 20% faster while maintaining the same "all-day" 18-hour battery life.

While The Apple Watch SE are using the S5 dual-core processor from the Apple Watch Series 5. And The S5 is up to twice as quick as the Apple Watch Series 3.

The S7 chip, which represents a minor performance improvement, is not a compelling reason to select the Apple Watch Series 7. When it debuted in the Apple Watch Series 5, the S5 was already a capable chip, and the S7 simply offers a more refined chip.

U1 Ultra-Wideband Chip

The U1 Ultra Wideband chip is only available in the Apple Watch Series 7. According to Apple, the U1 on the Apple Watch will "enable short-range wireless location to support new experiences such as next-generation digital car keys and AirTag tracking."

The distance between two ultra-wideband devices can be precisely measured by calculating the time it takes for a radio wave to pass between the two devices, which is much more accurate than Bluetooth LE and Wi-Fi.

Health Monitoring

The Apple Watch Series 7 includes blood oxygen monitoring. This feature allows the user to understand their overall fitness and well-being. The proportions of oxygen saturation will show how well-oxygenated blood is delivered throughout the body.

On the back of the Apple Watch Series 6, there is a blood oxygen sensor with four clusters of green, red, and infrared LEDs. They use an advanced custom algorithm to determine blood oxygen saturation between 70 and 100 percent by measuring light reflected back from blood.


Both Apple Watch Series 7 products and Apple Watch SE have the same usage time, estimated at about 18 hours. Your device's battery life will also depend on a number of other factors such as display settings or whether or not you have GPS enabled.

Additionally, the Apple Watch Series 7‌ features 33% faster charging than the Series 6 due to the new charging architecture, which itself also charges faster than the SE. Apple Watch Series 7 can reach 80% in just 45 minutes of charging.

6. Conclusion

The Apple Watch Series 7 is an upgrade over the previous Series 6 model, with a larger display, increased durability, and faster charging. The Apple Watch Series 7 will be the model of choice for those who want the most out of their wearable, thanks to its larger casing, always-on display, advanced health monitoring features, and variety of colors and finishes. 

If you are especially interested in health tracking, a larger display, fast charging, or a specific casing and color combination, the Apple Watch Series 7 is the model for you.

However, Because of its competitive pricing and generous feature set, the Apple Watch SE will be the go-to model for many Apple Watch customers, and it may be the best choice for those new to Apple Watch or users upgrading from a Series 3 or older. Because it shares so many features with the Apple Watch Series 7, you should probably opt for the less expensive model unless you value features like the always-on display or advanced health monitoring and can justify the extra cost.
