And in this guide, we’ll state the differences between the Apple Watch Series 8 Stainless Steel and Aluminium models to help you make a more informed decision.

Stainless steel or Aluminum – Which Model is Better?

Apple Watch Series 8 Aluminum vs Stainless Steel

In fewer words, the stainless steel model is better than the aluminum model because it’s more durable and has a more commanding appearance. The aluminum model is also very durable and it’s a more popular choice.

If you really want the cellular model and have the budget for it, the Stainless steel model is a better choice.
However, the aluminum model is cheaper, yet very durable. Moreover, it’s even cheaper when you opt for the GPS model. I have never used the stainless steel model, the aluminum model has always been my choice and so far, I have no regrets.

In summary, it’s a matter of your budget.

The Apple Watch 8 looks exactly like the Watch 7 and it comes with a few additional features which include a more powerful 256-g accelerometer that can detect when a car crashes and a temperature sensor that can monitor nightly skin temperature variation and ovulation for women. Beyond this, Watch 8 and 7 are typically the same.

WatchOS 9 is the current operating system for the recently released Apple Watches and it also supports Apple Watch 4, 5, 6, 7 and Watch SE. It brings a decent amount of interesting features which include the ability to track sleep stages, a new medication app, custom workouts, more watch faces, and a revamped compass app. You can read more on how to update your Apple Watch to WatchOS 9 and all the new features it offers.

Introducing Apple Watch 8

The Apple Watch Series 8 is a very durable and stylishly designed smartwatch. It comes in stainless steel or aluminum build paired with silicone bands that can be swapped. It spots a 1000nit bright LTPO OLED display that’s easy to read under any light condition.

The Watch 8 is available in two sizes; 41mm and 45mm and each of these sizes is available in Cellular and GPS models. The Cellular model is a standalone smartwatch that can make and receive calls without connecting to your iPhone.

Under the hood, is the S8 64-bit dual-core chip that delivers a super-fast performance plus and it has a sophisticated user interface that’s very easy to use. Navigation is via the touch-sensitive screen, digital crown, and physical button.

The Watch 8 packs a 32GB storage capacity that lets you add music to the watch. It also has a speaker, microphone and NFC chip that enables Apple Pay.

Like the Watch 7, the Watch 8 is a comprehensive health tracker that can monitor all of your daily activities. It will track your steps, sleep, stress, blood oxygen, respiratory rate during sleep, heart rate, ECG and it features loads of workout modes.

Battery life hasn’t changed as the Watch 8 can last just up to 18hrs. Though, the low-power mode can help you get a little longer battery life.
