Hi ! To replace the Xtal is easy .. any watchmaker can do ! The difficult part is to secure the Xtal ! If you go to Omega official, to have an original part (with the logo), they more than likely will ask you to do the work in their shop, they will tell you it needs an overhaul .. etc .. and you will end up spending big bucks ! at least that's my experience in my part of the world ! You can also find an aftermarket part and get it installed by your watchmaker .. much much cheaper ! only thing is the aftermarket part shall probably sit higher on the watch which I personally find very regrettable ! So, here you go .. let us know what route you take ! Good luck !
