For me the worst part of current CGMs isn't the needle or the very thin piece of plastic it leaves behind with the probe. Rather, it's the effect on the skin under the patch and the residual adhesive. So from that perspective a watch would be cool.

Indeed though, advancements in (affordable) closed loop tech matter more than where the CGM is worn.

Can you say more about the plastic left behind? Polyurethane coating on the cannula?

Been using a dexcom g7 for a few weeks as a test. Pulling the sensor off can be painful, and leaves behind adhesive residue when I do it. And there's also a bit of inflammation in the area since it sticks a small probe into you, which sits there for 10 days.

Oil slick is a skin safe tar remover and searching for that using a pummice stone was reccomended on reddit.

I mean the probe itself, which appears to be wire encased in plastic. When I said "left behind" I just meant that the probe is placed below the skin as intended, not that anything remains after the sensor is removed. This is the part that would be considered "invasive."
