I have a Big Bang Unico Titanium Blue Ceramic 42mm, ref 441.NL.5171.RX. I want to pickup another strap but can’t decide which one. The stock one is black and blue lined rubber. I’ll most likely buy it online via the eboutique. I am thinking about the black and grey beige black camouflage structured rubber. Fun Strap! Or perhaps the blue or dark blue soft touch (grained calfskin). Thoughts? Other ideas?
