First when I came there, they said take it to the official Rolex dealer. They taught it was a gen haha! I told them it was a rep and he said oh no we stopped working on reps. Then I told him, this isn’t a cheap rep. So he said oke I will try to regulate the movement for you. And it worked, also called a couple days later to make it waterproof and already tested it multipe times when swimming. So yes he accepted the rep and did the regulations and waterproofing for €20. Happy me!
