It does change the shade of blue depending on the sunlight.
That looks great! Do you happen to know how much it weighs on the bracelet? Tried one on at an AD and it was feather light but the 9k price was steep especially considering the new ceramic 300m is less.
I think the other fantastic thing about titanium is how fast the watch adapts to the surface temperature of your skin (another reason Ti is used in dental implants). Pair that with it's very light weight it makes wearing a Ti watch of almost any size seem to disappear when it's fitted correctly. I barely notice this 45mm Ti PO when it's on my wrist. And the addition of the Ti micro adjustable clasp has made it even more comfortable!
