Which Should You Buy: Apple Watch Series 3 Or Apple Watch Series 5?


Smartwatches are great for anyone regardless of their fitness interest. Not only do they track exercise, but they can store music, keep your organized, and so much more. One of the leaders in smartwatches is Apple with its highly rated Apple Watch. Now offered in the latest Series 5, you may wonder which model is right for you. Apple has recently marked the Series 3 Apple Watch down, making it a fantastic option for those looking for a capable and reliable first smartwatch. As Apple no longer sells the Series 4, taking advantage of the cost savings of the 3 may be a great option for what you’re looking for. So, what are the main differences between Series 3 and 5? In truth, there aren’t many! We’ll take a look at the operating systems, display, sensors, battery life, and cost of Series 3 and Series 5 Apple Watches.

Operating Systems

With the Series 3 watch, it will likely have watchOS 5 installed. However, with watchOS 6 available, it can be installed on the 3. So, you can run the latest operating system on a 3 without the cost of a 5 watch.

Watch Display

The Series 5 has a slightly larger screen that occupies more of the watch face than the 3. The watch face sizes for the 5 watch are 40mm and 44mm, whereas the Series 3 sizes are 38mm and 42mm. For a thinner profile, the 5 is just 10.7mm thick. One of the most obvious differences that sways buyers towards the Series 5 Apple Watch is the always-on display. Instead of shaking your wrist or tapping the watch to wake the screen, you can enjoy information like the time, fitness goals, heart rate, and other stats by simply looking down. The new Low-Temperature Polycrystalline Oxid OLED makes this possible without draining the watch’s 18-hour battery life. The Series 3 watch is mostly black and motionless when not in use.

Useful Sensors

With the Series 3 and 5, you get the benefit of the optical heart sensor, NFC, GPS, altimeter, speaker, Wi-Fi capability, LTE coverage, and a wireless chip. Plus, each can handle water up to 50 meters. However, the heart sensor of the 5 watch has the ability to take an electrocardiogram to identify irregular heart rhythms. It also has fall detection, which is a great perk for older users like grandparents. The 5 will provide the option to call emergency services from the watch, which could truly save a life. Alongside the GPS, the Series 5 Apple Watch also boasts a compass.

Battery Life

No difference here. Each of these Apple Watch models boasts an 18-hour battery life.

Overall Cost

The cost of the Series 3 versus the 5 is one of the biggest differentiators. With its enhanced features, the Series 5 Apple Watch runs around $400, whereas the Series 3 will cost you about $200.
