The First 8 Things You Should Do With Your New Apple Watch - TmZ Blog

By default, your Apple Watch’s sound is turned on. At first, it’s fun to listen to all the unique chimes and tones that Apple put into its wearable. After a while, though, it might become irritating, especially if you do have a lot of notifications. If you’re someone who usually keeps their iPhone on silent, you might want to consider the same for the watch.

To mute your watch, just wake it up, swipe up from the bottom, then tap the alarm bell icon in Control Center. To simply lower the volume, go to Settings > Sounds & Haptics on the watch or in the Watch app, then use the volume icons to adjust accordingly.
