The Apple Watch 4's key feature is really its design - we say that because while the extra health benefits are something that are worthy and really make this an attractive device for those in need of them, the pool of people this is relevant to is smaller than just those looking for a new watch. That is for shielding and grounding purposes. If you get a spare you can of course replace it. But be careful not to damage the display cables. Siri’s skills are also built into its own watch face.
