Hello Zaf, I hope you're keeping well. Per your advice, I have taken my watch to a local reputable watchmaker who has been practicing for over 30 years. Unfortunately, he was unable to find the right replacement generic acrylic glass. He tried a number of configurations but was unsuccessful. I'm now helping him to source a suitable crystal. The diameter is 33.5mm, but it requires extra high dome with chrome/silver tension ring. The GS XHD.32-3/4 has 6.8mm height and should be good, but it doesn't have tension ring. Similarly, Stella has the XHEC but no tension ring, and I can't find it for 33.5mm size at any rate. The watchmaker insists that the crystal should have tension ring.
The problem is that the majority of other crystals with tension rings seem to not high enough dome for this particular watch model. The closest I can find is the Sternkreuz High Dome Acrylic Crystal with Chrome tension ring, and the height of that crystal is 5.2mm. Based on your experience, do you have a recommendation for the correct generic crystal that can be sourced? or would you know where an OEM crystal might be found?
Thank you again for your valuable insight.
