The Omega Super Series Moon Dark Face reference number 431.53.41.21.01.001 is a Clean Factory build sourced for buyers who understand the difference between a standard replica and a properly executed superclone. Clean Factory production applies tighter tolerances across case finishing, dial printing, and movement regulation than the broader replica market — and this piece reflects that standard across every component.

Movement & Performance
The moonphase display requires precise disc printing, clean aperture finishing, and accurate hand alignment — three criteria that lower-tier production cannot maintain reliably. At Clean specification the moonphase disc artwork holds up under close examination and the display reads clearly at wrist distance, which is the standard a well-executed moonphase complication should meet.
The Clean Factory standard applies most visibly in the bracelet — where link tolerances, clasp resistance, and surface finishing either hold up or fall apart quickly in regular use. On a Clean specification build these details are consistent throughout, not just in factory photography.
