The Series 6 is the more recent model, and it was launched in September 2020, while the Series 3 was launched in September 2017.

The Series 6 is also more expensive than the Series 3, with a starting price of $399, compared to $199 for the Series 3.

Another aspect to consider is the cost of the cellular connectivity, which is an added expense for the Series 6.

Environmental and Durability

In terms of materials, both the Series 6 and Series 3 use Ion-X strengthened glass on the display, which is more durable and scratch-resistant than regular glass.

Additional watch faces and bands

Both the Series 6 and Series 3 have a variety of watch faces and bands to choose from, but the Series 6 has more exclusive and limited edition options available.

Updates and Support

The Series 6 is a newer model and it has received more updates and features since its launch. It also supports the latest software update and has a longer support period compared to Series 3, which is still supported but it won’t receive any major updates. This means that if you’re looking for the latest features and capabilities, the Series 6 is the better option.

Comparison with other competitor smart watches

When comparing both the Apple Watch Series 6 and Series 3 with other smart watches available in the market, both stand out for their advanced fitness and health features, and strong integration with the iOS ecosystem. However, other smart watches like Samsung Galaxy Watch and Fitbit Versa do have similar features and functionality, but they might lack the level of integration and seamless experience that Apple watches provide. For example, the Samsung Galaxy Watch has a rotating bezel for navigation, which can be a useful feature for some users, but it lacks the haptic feedback and digital crown found on the Apple Watch. Additionally, Samsung’s smartwatch doesn’t have the same level of integration with iOS devices as the Apple Watch. Fitbit Versa also has similar fitness and health tracking features, but it lacks the cellular connectivity, ECG and SpO2 monitoring and the ability to make calls and send texts directly from the watch.

Noise alerts

Another important feature that differentiates the two models is the Noise alerts, which is exclusive to the Series 6. This feature uses the microphone on the watch to detect loud sounds and alerts you when the decibel level reaches a level that could be harmful to your hearing. It is a useful feature for people who work in loud environments or frequently attend loud events, as it can help prevent hearing damage.

Fall detection

Fall detection is another feature that differentiates the two models. The Series 6 has an advanced fall detection algorithm, which uses the watch’s sensors to detect when a fall has occurred, and then sends an alert to the user and their emergency contacts. The Series 3 has this feature too but it is not as advanced as the Series 6 and it doesn’t send an automatic alert to the emergency contact.

Sleep tracking

Sleep tracking is also another feature that differentiates the two models. The Series 6 has a more advanced sleep tracking feature, which uses the watch’s sensors to track and analyze your sleep patterns and provide personalized recommendations for improving your sleep. While the Series 3 has a basic sleep tracking feature, it doesn’t provide as much detailed information as the Series 6.

Conclusion

The Series 6 is the more recent and more advanced model, with a larger and more vivid display, more powerful hardware, more advanced sensors and additional features like blood oxygen monitoring, ECG, noise alerts, fall detection, advanced sleep tracking and more.

Additionally, if you’re looking for a device with a long battery life, the Series 3 with its 24 hours battery life compared to the 18 hours battery life of the Series 6, could be a better option.
