Im not too sure.
"Functioning normally
But not the phases of the moon.
Will move.
Walk once a day"
Okay, I think what she means is that it isn't a true moonphase.
What I mean by this, most "replicas" when they advertise moonphase, it's actually just a day counter, so it ticks over every day, one full rotation in 31 days / 1 month This is often super common with the Miyota 9015 modified "complete calendar" replicas.
real moonphase tracks 29.5 day cycle, it's why the complication is highly esteemed in watchmaking, it's not as simple as making it "tick over" every 24 hrs.
