Thanx for the replies, I just called the service centre: They told me there are NO Rolex SA manufactories in China or Asia, BUT the dutch service centre buys the GENUINE ROLEX SWISS MADE PARTS from a opfficial Rolex AD in Macao/HongKong wherever...

Which means my employee misunderstood.:/

The parts are GENUINE but make a trip around the world so to speak

Geneve/Biel->Macao/HongKong->Netherlands
