Apple Watch should connect automatically to any network I was previously connected with on my iPhone.
At my university I need to register devices for network access by providing them with a MAC address. There are no further logins required and the network is open.
I connected to this network with my iPhone and it works. Then I registered another device using the MAC address from settings -> General -> About -> MAC Address.
However, the Apple Watch just doesn't connect.
How can this be debugged?
Have you tried to "hard reset" the Apple Watch?
Tap on Reset.
Tap on Erase All Content and Settings.
Tap on Continue to confirm the reset.
Bluetooth can only connect to 1 device of a type at a time.
For example, you can only connect to 1 pair of headphones (AirPods) or 1 mouse at a time. You can connect to multiple devices (AirPods and a mouse) at the same time because these are different devices.
You didn't provide enough info on the devices you can't connect to, the errors you received (if any), or the troubleshooting steps you've already taken, for me to assist you with the "double connection" in your question. Please see Help and then edit your question to include all relevant info.

Unfortunately watchOS 3.x can't connect to a Wi-Fi secured by WPA2-Enterprise.
I have experienced the same behavior in the past with watchOS 2.x as well.
This assumes:
With iOS you can enter your credentials. They will get saved and can be transferred to watchOS. The certificate, however, cannot be provided from iOS to watchOS.
Let Apple Know
Contact Apple and let them know. Apple cares about user's feedback. Use Apple's feedback form for Apple Watch.
Updated answer
divB has pointed out that the network uses a MAC address filter instead of the WPA2-Enterprise security protocol
Please make sure to provide your Apple Watch's MAC address to your university as well as your iPhone's MAC address.
You can find it on your iPhone:
Watch.app > General > About > Wi-Fi Address
