When exploring the outdoors, knowing what direction you're headed is generally more important than keeping elapsed time — which is why the Seiko Prospex SRPH15 swaps the traditional timing bezel for a compass. Designed to provide a rough indication of direction, the bezel is a metallic green to match the green sunray dial. The latter has a small timing ring around the edge and LumiBrite hands and markers, as well as a small date window at 4:30. Powered by an automatic movement, it has a sapphire crystal for superior scratch resistance, a screwdown crown and caseback, the latter etched with ground to air emergency codes, and sits on a matching stainless bracelet.
