I think the blue dial works better with the stark, black strap than the white dial in a similar 5119. I tried on a 5119 YG, but to me. the black strap was just too overpowering. The strap was also a little thinner, non-padded.
I do like, however, the 5120. Ultra thin and automatic. Very simple, classic design.
If you see it in the metal and like it, go for it! Nice, dressy watch.
