Rubber strap is super comfortable, though I worry constantly about the coated clasp. The numbers and triangle in the bezel are bright, the green ripple effect is not very bright and doesn't last long. Here's a photo with no forcing of the lume. I was outside half an hour ago and this is the natural lume effect in the dark.
Tough to say whether I would recommend this or the titanium. Both very cool. This one wears smaller than 40mm, just because it's black. But then the titanium also wears smaller than 40mm... compared to my 40mm Calibre 5 green dial.
