Apollo astronauts wore the original on the moon. Buzz Aldrin’s piece is in the Smithsonian. The watch was tested in vacuum, near-vacuum, freezing temperatures, and (in 1962, by an actual NASA engineer) the inside of a centrifuge. It’s a watch for the worst day of your life, designed by people who had thought hard about exactly that day.
Ours is a wall clock. Vacuum-rated only against household dust. The visual lineage is otherwise intact: tritone subdial layout, tachymeter bezel, hands sized for one-glance reading. The dial is flat matte black with white indices that pop hard under any kind of room light.
It’s a chronograph for your wall, in the lineage of one that went to the moon. NASA did not endorse this. NASA does not know we exist.
