Which Should You Buy?

Without mincing words, Watch 6 is the best choice, it’s the most sophisticated out of the three smartwatches. It features blood oxygen tracking which both Watch 3 and 5 lack, and it’s also powered by a more refined S6 chip. Both Watch 5 and 6 feature Family setup, noise hearing app, incidental fall detection, ECG, international emergency calling, compass, and always-on display, all of which Watch 3 lacks. Watch 5 and 6 are also available in three different materials compared to Watch 3 that is only available in aluminum.

So, Watch 5 is a cheaper alternative to Watch 6, while Watch 3 would pass as an entry choice if you’re really tight on budget. It’s a great smartwatch featuring lots of fitness features with music storage, loudspeaker and, microphone.
