Interestingly, Series 6 also features the U1 chip or Ultra-Wideband support, introduced in iPhone 11- it enables precise location and improved spatial awareness. All three watches run the WatchOS 7; however, the Series 3 may soon lose out on support for updates.

Features

  • Series 6: Blood O2, ECG, Optical Heart, Always-On Altimeter, Louder Speaker, Noise Monitor, Fall Detection
  • Watch SE: Optical Heart Sensor, Always-On Altimeter, Louder Speaker, Noise Monitor, Fall Detection

The Apple Watch Series 6 comes with several new features, including a Blood oxygen sensor, Optical heart sensor, ECG, Noise monitor, Digital Crown with haptic feedback, GPS, Compass, Always-on altimeter, and a second-gen speaker and microphone.

The Watch SE has the same accelerometer, gyroscope, compass, GPS, and altimeter as the Series 6. It also carries over the same Optical heart sensor, Noise monitor, Digital Crown with haptics, Always-on altimeter, speakers, and microphone from the former. However, you won’t find the Blood O2 sensor and ECG.

Launched in 2017, the Watch Series 3 lacks several new features. It gets an Optical heart sensor, regular Digital Crown, GPS, and a standard Altimeter as opposed to an always-on Altimeter. The speakers on the other two are 50% louder than Series 3.

Series 3 also doesn’t feature fall detection, which could be a life savior in some cases. Plus, it no longer comes in GPS + Cellular version and hence won’t work with Family Setup.

Battery Life

All three smartwatches come with a built-in rechargeable lithium-ion batteries touted to last up to 18 hours on a single charge. You can charge them with Apple’s Magnetic Charging Cable.

Price

In India, the Apple Watch Series 6 stands as the most expensive of the trio at a starting price of ₹40,900 ($399 in the US) for the GPS variant. Whereas, the GPS + Cellular model costs upwards of ₹49,900 ($499 in the US).

The Apple Watch SE will set you back ₹29,900 ($279 in the US) for the GPS model and ₹33,900 ($329 in the US) for the GPS + Cellular variant. The dated Apple Watch Series 3, on the other hand, starts at just ₹20,900 ($199 in the US).

Like other Apple products, all three watches are costlier in India due to taxes. If you’re planning to buy any of the cellular variants from a different region, do check if it supports Indian bands. An Apple Watch purchased in the USA will not work with Indian cellular networks.

Should I Buy Apple Watch Series 6, Watch SE, or Series 3?

The Apple Watch Series 6 is the company’s most advanced smartwatch with a Blood Oxygen sensor, Always-on display, ECG, fall detection, and an always-on altimeter. The cheaper Watch SE offers the same large screen while skipping a few features like the always-on display, ECG, and Blood O2 sensor.

Apple Watch Series 3, on the other hand, gives you the core fitness and health features of an Apple Watch at an affordable price. However, in comparison with Watch SE, it lacks fall detection, gets a regular altimeter, lesser storage, and comes with dated hardware.

All-inclusive, if budget is not a constraint, you can straight up buy the new Series 6. However, if those extra features aren’t on your list, the Watch SE would be an ideal choice considering the lower price. Buying a Series 3 may save you even more cash, but then again, you’ll lose out on a lot of crucial features.
