It is muchos $$$ because of the ceramic case, bracelet and the swiss quartz movement. I don't think the 'diamonds' are of a very high quality.....it are just plain old zirconias, like they use in 5 dollar ear rings.
Don't worry. I really don't think anyone could call her out because of the Zircs ... not even an AD. Unless she takes it of and he uses a diamond tester ... which is highly unlikely
It's not the watch that has to look real.... it's the wearer! ( a $50 jumpsuit and a $5000 watch don't match)
