Seiko Prospex SPB175

Prospex's ultra-popular Sumo line of dive watches has a very cool trio of new additions in these Ice Diver models. The colors of each, the SPB175, SPB177, and SPB179, are inspired by the variety of colors that you can find in icebergs (and yes, there are green icebergs). On top of their unique colors, they're also equipped with a waffle-textured dial and tough sapphire crystal.
