Whether you’re a first time Apple Watch owner or somebody that upgrades to the newest model every year, there are always things you can learn. Chief among them is learning what the various icons and symbols that appear on it actually mean.
Apple has developed a number of icons and symbols that are designed to alert you to something without having you unlock or touch your Apple Watch. And the good news is no matter which Apple Watch model you have — from the older Series 3 to the brand new Series 8 or Ultra — all of these icons are the same.
What does the Red Dot mean?

When you see the red dot notification icon, it simply means that you have received a notification and you haven’t read it yet. This notification could be a wide variety of things, everything from a text, a missed phone call, or notification from basically any app.
If you see the red dot notification icon, you can check what it is by simply swiping down from the top of the Apple Watch. When you then swipe away from this notification screen and back to your default watch face it’ll mark those notifications as seen and the red dot will disappear.
