Crystal for Omega 166.0190

[jiwilliams79]

Hi Everyone,

I am looking to source a new Crystal for an Omega Geneve Oversized TV dial.  I am pretty sure the part number I am looking for is PX5259, but not 100% sure.  I have struck out on the bay and other googlable sources and wanted to check if anyone here might have a suggestion for where I could try next.  

I think the main problem is it's a fairly large square crystal that wasn't used in many models...

Thanks for you help!

one of the things to remember when giving us an Omega case back number is to tell us what it's made of. For instance this case refers to two separate cases Steelcase and a gold plated case. I've seen as many as four preps five separate cases with the same number. The numbers aren't necessarily super specific and sometimes there can be variations of things like crystals depending upon the case like I did notice the solid gold cases may have a different crystal number then a Steelcase. Otherwise usually just tension ring color changes and that changes the letters at the beginning.

so for instance if it was the yellow plated case this is the crystal description and number

063PX5259 | GLA PLEX 2N RIN SP 30.71X30.71 H3.6

and if the stainless steel version this is what we get

063PZ5259 | GLA PLEX ST RIN SP 30.71X30.71 H3.6

descriptions of the same but one letter changes in reference to the color of the ring inside.

and just in case you're not familiar with how the numbers play out

Thanks!  That's great advice as I did not know that!  So, this one is the stainless steel version, but I still have the tension, umbrella, "square" and gasket so do I need to get another one?

 

Once again, very much appreciate the information!

I'm not quite sure what were talking about here so maybe a picture

then if you go to cousins and search for the case number the documentation you get a parts breakdown.

notice how even for the stainless steel case there's three separate dials for this. Which is the same problem with the casing numbers they point you in a general traction but they're not very specific.

okay the metal ring which should you want to hang onto just in case that goes in the crystal. So that will come with the crystal. This is where if for some reason you couldn't get the stainless steel version of the crystal you to get the gold version and then you'd swap your ring. Plus if there was a generic which it probably isn't you would want to use the original ring can sometimes are shaped differently.

Then the red thing? okay that may be a problem let me go look at a source of information that you don't have access to.

okay I was having a mental confusion I was being bothered by something in the drawing. Where I go I can put the mouse over the item in the drawing and it lights up in the list so I know exactly what it is so the crystal comes with the metal ring in the drawing the metal ring is shown underneath like a separate components and it would light up in the list way out stupid John that is not a separate component that's the crystal and your red thing must be the case back gaskets because that's the only other gasket they have

which is a guess means that that is and of course by the shape that's a friction on back yes you have to have that ringand I don't know why there's two sets of numbers I think that's also in the PDF so in a case you still need it if that one doesn't work otherwise the watch will not be water resistant
