Need advice - GMT watch

[bofon13]

Hello!

I have a green sub, the "hulk" and i am very satisfied of this watch! Beautiful! The best watch there is, and i like all about it, but, after having a lot of other watches i still dont find the perfect GMT watch that could give me what the Hulk gives me when thinking about divers. So, the questions is, EXCEPT the rolex (GMT and Explorer) what would you chose as a GMT (dual time watch) that could be a nice pair with the Sub?

What i would like the GMT to be:
- steel bracelet
- reasonable wr (100+)
- inhouse movement
- reliable (to last me a life time) - i will buy it when i will relocate to another continent and i would like a watch that shows the time at my country of origin. I will leave it to my children.
- price range - around 10-15.000

What i had in the past war the reverso JLC - squadra hometime (loved it but 50m wr... too low) and i had an Ebel BTR GMT - not bad, but... not enough salt and pepper :)

PS - writting this i cant find a better one than the Rolex GMT ceramic. Need your advice about someting different.

Thank you! :)
