Hey there PeterCatalin,
It sounds like you may have already enabled AssistiveTouch, but are unable navigate your watch using this feature. Perhaps motion pointer would help. Taking a look at Use AssistiveTouch on your Apple Watch,
"Navigate your Apple Watch with the motion pointer
Another way to use AssistiveTouch is with the motion pointer. The motion pointer appears as a circle icon on your Apple Watch screen, and you can control its movement by tilting your Apple Watch. You can activate the motion pointer by shaking your wrist or by using the action menu.
How to activate the motion pointer by shaking your wrist
- Tap Settings > Accessibility > AssistiveTouch > Motion Pointer > Dwell Control.
- Tap Shake to Start to turn the feature on.
- Raise your Apple Watch, then shake your wrist to make the motion pointer appear.
How to activate the motion pointer using the action menu
- Bring up the action menu using your hand gesture. The default gesture is a double clench.
- Move forward in the action menu using the default pinch gesture until Interaction is selected, then tap it by clenching your fist.
- Tap Motion Pointer.
When you move the motion pointer and the pointer hovers over an item, you can tap the item using a hand gesture. Or you can allow the motion pointer to select the item automatically after a specified interval. You can also set the motion pointer to bring up the action menu when it selects an item on your screen.
The motion pointer can help you swipe on your Apple Watch screen with hot edges. When you hover the motion pointer near an edge of your screen, a swipe is performed in that direction. You can customize these hot edges in Accessibility > AssistiveTouch > Motion Pointer."
Have a good one!
