the 2 watches aim at two very different wearing/enjoyment feelings.
I have a 5712 and would totally see myself having a 5711 as well. Thus I can even more understand the complementarity of both references.
A sportier and usefulness 5990, more spectacular, on one side and the elegance, beauty and discretion of the 5711 on the other.
I like the black dial as well and don't think I have preference for the blue one.
Enjoy them both and thank you for sharing the pictures!
Cheers, Mark
