Well I've had my hamilton Khaki Chrono at my watchmaker for a little while and asked him to replace the crystal (while he was doing a COA). After receiving two generic replacement crystals that don't quite fit properly, he wanted to get one from Swatch Group (or the parts vendor in the states that deals with them) and they won't sell him one. I know they had restricted ETA movements, but didn't realize that they were attempting the same thing with parts. I know why they are doing it, they want to get people to send their watches to the Swatch service centers for any work. I would rather give a watchmaker I know the business, and not have to send it back to Swatch Group. Seems like a very shortsighted business decision. I may be more inclined to buy a different brand if I don't have to deal with that stuff.
