Suunto 7 not pairing with iPhone 12

How do I check that Bluetooth is enabled on my watch? I’m in a phase of selecting language and accepting terms of contract and pairing using Wear OS is not working. So I don’t have any normal view (settings, etc.) If I press power button for a few seconds, I get settings view, but there is no Bluetooth, only Wi-Fi. And pairing issue is preventing me opening Suunto app as well, is not connected.

All of these worked well when trying other iPhone12, so the problem is on my phone.

Could I some how restore (icloud) backup in iPhone from time, when all the apps worked?

This is my iPhone12 Wear OS error log, when trying to establish connection to my Suunto 7 watch, could you tell, whether it helps locating the error or what to do to repair it?

Problem solved. There was some settings wrong in existing setup in my iPhone12 and when I restored backup from iCloud, it didn’t work. But when I didn’t restore it and went for blanco factory settings, installed all the apps again including Iwear OS and Suunto app, it starting to work again and paired with the Suunto 7 watch.
