The dial is also brushed black ceramic [ZrO2] and features laser-engraving to create raised waves.The skeleton hands and raised indexes in PVD titanium are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.The watch is presented on an integrated black rubber strap with a polished-brushed black ceramic [ZrO2] buckle, and is driven by the OMEGA Master Chronometer Calibre 8806, which can be seen through the sapphire-crystal on the wave-edged caseback.
