Anyone have a tutorial on how to change the crystal?

[ChaoticBliss]

Hi All,

I have a 36mm Datejust (116200) that I would like to change the crystal on. Does anyone know how to do this on a Rolex? I know how to remove the movement but I am unclear if the crystal comes out through the back or if I need to pry off the bezel. I have access to a crystal press if that is required.

Thanks

Hello
to replace the crystal first remove the bezel , dont try to lift all in one go with the pen knife lift the prisle lightly 180 degrees round from the lip and so on where there is the smallest gap round the beel from that point allways then remove all loose particles of dirt put a thin blade in under the nllon glass gasket and prise up going 180 degrees round and always consentrating on the smalles gap .after removed then clean lip that the gasket goes on. obviousley the movement and dial should be removed if you can. make sure lip that the gasket goes round isclean and free from corrosion or rust by various implements if you can remove with peg wood toothpicks if thats all thats avaliable . if ther is pitting on this vertical lip then silicone the bezel lip silicone should be use in ant case. then make sure all hands and all functions are still operational and that the acrylic or crystal is clean. press the gass and gasket on horizontal and then place cleaned bezel overthe glass and push down with a even horizontal preasure if it seems to snag stop and get the horizontal preasure correct and watch with an eye glassasa the starting fault that is common is that people dont see the bezel going down squint as this may only be 0.25 of a mm out ans most evesight will not see this amount of variation between one side and the other. If you dont have a bezel press then you should use something if you are a novice then dont break everething when any thing snags or extra presure is required then. stop and look you wont break as many parts if you use a light preasure this is the case on most components the smaller the easier broken , even so these glasses and bezels are strong and can take most atempts to fit anyway if you havent a bezel press then you can use anything that is round and with a diameter that willallow the glass to come up through the bezel a wooden egg cup can do this job without marking the case in any way with somthing suporting the case i dident say a wooden egg cup but wood is soft and as long as it doesent snap in two if a film of silicone of selafane is placed over the bezel and the glass goes on with the bezel going all the way down then you should have a 100m vacuumable watch.
