At first glance, this watch looks like the "classic" Speedmaster, but quickly, the eye is drawn to the 6 o'clock position which features a highly detailed Moonphase function.

"Its high resolution image, black and white high contrast, is as detailed a picture from NASA." 

This Omega Moonphase is powered by the C.O.S.C certified Co-Axial Chronometer Master Calibre 9904 (368 components, 60 hours of power reserve) that displays moon phases ultra-precisely and only need to be adjusted every ten years by a few rotations of the crown.
