** Facing issue for watch unreachable, I have tried for real device as well simulator**

When examining a Watch Connectivity issue, I typically start with checking if the issue occurs in the following Apple sample, which demonstrates how to use Watch Connectivity:

Transferring data with Watch Connectivity.

If it does, I'd suggest that you file a feedback report with your steps that reproduce the issue, and share your report ID here. From there, we can check if it is something on the app side or on the system side.
