As I've mentioned before, this watch really needs to be viewed in person to be fully appreciated. Because the renders and photos don't show how different lighting affects the colors on both the front and back of the watch.
This video provides a glimpse. At 3:04 the video shows how the case-back sapphire color shifts between green and red. At about 5:43, one can see how the front dial's colors are also affected by the shifts in light. Which for me was even more dramatic when viewed in person, compared to this video.
