Black-faced, stainless steel chronograph, manual wind wristwatch with a Plexiglass crystal, solid case back with a blue removable protective cover, anti-vibration and anti-magnetic dust cover, black tachymeter bezel and sub-dials, without date or day complications, powered by a caliber 861-based movement. Engraved on the case back is, “Flight-Qualified by NASA For All Manned Space Missions / The First Watch Worn on the Moon.” There appears to be tritium powered phosphorescent lumen on the hands and index markers of the watch.
