How do I adjust the volume on my I watch?

I'm curious, how exactly does one go about adjusting the volume on their I watch? Is there a specific button or gesture that needs to be performed? And what if the device is not responding to my attempts to adjust the volume? Is there a troubleshooting process I can follow to resolve the issue? I'm eager to learn more about how to optimize my I watch experience and ensure that I can hear notifications and alerts clearly.
