I am having a bit of an issue with my Breitling Bently GT I have had it a couple of months now and now the crown will not screw down I dont know if I have damaged the crown or what. I push the crown down and screw it on but it doesnt tighten I belive maybe I have stripped it. Can this be fixed? If so who can fix this it is pretty much my favorite watch and I would like to get this fixed asap.
