Batman/girl for me.
I don't find the Milgauss very interesting.
Then I.must admit that the BLNR is by far my fave Roli and one if my favourite watches all round.
It is also not very "formal," it is a thick steel tool watch with a steel bracelet, hardly the kind of watch to wear with black tie. It's natural territory is from smart casual to casual, it can be stuffed under a business suit if one must.
The BLNR covers more or less the same ground.
I wear it with a suit too - even though I really should know better.
The more I research, the less interesting Milgauss just becomes. Or is it just the photos that make it so boring?
