Product 2: Apple Watch SE 3

Product 2: Apple Watch SE 3
No score yet

4.2

Charging is reasonably convenient thanks to the USB-C cable setup, even if it still relies on a proprietary watch connection.

1.0

ECG functionality is absent on the SE 3, and several reviews frame that missing feature as one of the main reasons to consider a more expensive model.

fit
Product 1: Polar Grit X2 Pro
3.1

Fit is more polarizing on smaller wrists because the 48 mm case size makes the watch wear noticeably large.
