Where is the control panel on Apple Watches running watchOS 10!?

In Apple Watch, we were used to certain things. Like swiping up on the watch screen, to open the control center. In watchOS 10, this gesture is no more, and opening the control center will go in a different way. People who just updated to watchOS 10, can become a bit confused. How to open that control center?!

To open up the control center on an Apple Watch running watchOS 10, you must press the side button Once. To close the control center, please turn your wrist away or press the side button again.
