As someone upgrading for the original apple watch, I am very comfortable with the new watch and new features. Sorry that my original watch had battery swelling issues but this was a worthy upgrade.
The stainless steel and screen are quick to scratch, so get a screen protector and rhino crash guard to protect the sterling silver. Admittedly will add some bulk, but u have just purchased a $600 plus watch. In terms of the watch itself, I love it. My favorite feature is being able 2 answer calls from my watch.
Apple Watch 6 is great, it know when you are washing your hands and turn the timer on, read your blood oxygen which is great also. This is my first watch with Apple and it wonderful
