Editor's Notes

So, since earning the crown of the first watch on the moon, this OMEGA Speedmaster Moonwatch has been on all six lunar missions and is the only watch certified by NASA for use on spacewalks. Do we need to say any more? An absolutely incredible piece of history.

We love the history, function and aesthetic of this OMEGA Speedmaster Moonphase Co-Axial Chronometer. Watch the moon on the dial and the Co-Axial Master Chronometer 9904 movement through the caseback.
