Both models are engineered from high grade brushed 904L stainless steel, a highly-corrosion resistant and harder to machine type of steel only used by a handful of watchmakers. The watches feature single piece curved dials, domed antireflective flush-fit sapphire crystals and large easy-to-use crowns. The unique design architecture makes them as distinctive as they are legible. Both watches mark the first time AERA used Globolight© on its indexes and markers. Combined with hand-filled Super-LumiNova, this creates a uniquely bright and longer-lasting afterglow, offering exceptional visibility in low lighting conditions and an unparalleled at-a-glance field of view. It also gives the markers and numerals their distinct 3D effect.

The cases for the D-1 Ocean Diver and the P-1 Moon Pilot are engineered to convey rugged simplicity and easy wearability. Both watches run on the self-winding Swiss Sellita SW200-1 Elabore grade movement, with a 38-hour power reserve. They come with two quick release straps  with 904L buckles and each watch is delivered in its own bespoke pouch, handmade in the UK using Italian pebble-grain calf leather. The watch's  unique serial number is engraved on the case back and lug.
