triplehd Posted March 21, 2007 Report Share Posted March 21, 2007 I am trying to find the correct diameter size and thickness for the Saphire crystals that are used for Omegas, such as the Bond, Pro & GMT versions, as show in the link below: Omega Seamaster Quote Link to comment Share on other sites More sharing options...
krustybrand Posted March 21, 2007 Report Share Posted March 21, 2007 Measuring a spare Omega crystal (062 SA 3008) I happen to have shows it to be 30.52mm diameter and 2.57mm thick. Quote Link to comment Share on other sites More sharing options...

Thinking about getting some spares just in case there's another A/R Run. Found a place where the crystals are relatively cheap. So, I think I'll be safe if I order a couple 30.5mm in diameter and 2.5mm thick - flat (not domed). Thanks Krusty ! Quote Link to comment Share on other sites More sharing options...

As well, the AR coating is almost not noticable. This is the crystal used on my gen SMP Chrono as well, and its AR is barely noticable - most unlike the genuine PO.

It's noticeable when you compare it to a domed crystal without any coating that picks up reflections from all over the room. Quote Link to comment Share on other sites More sharing options...

Chief- Do you recommend a flat crystal or a domed crystal? Quote Link to comment Share on other sites More sharing options...
HauteHippie Posted March 22, 2007 Report Share Posted March 22, 2007 Chief- Do you recommend a flat crystal or a domed crystal? I think domed is correct for the SMP. PM flavor flav to confirm. He has a few gens. My SMP rep has a domed crystal, but it's this model: Quote Link to comment Share on other sites More sharing options...

Guest jagleaso Posted April 6, 2008 Report Share Posted April 6, 2008 I had this question too!? Quote Link to comment Share on other sites More sharing options...
ryaku Posted April 6, 2008 Report Share Posted April 6, 2008 I'm interested too Quote Link to comment Share on other sites More sharing options...
triplehd Posted April 6, 2008 Author Report Share Posted April 6, 2008 The size for these crystals are 30.5mm and 2.5mm diameter. You can get an authentic Omega crystal from Ofrei - but it will run ya about $150. I beleive it's single sided A/R. I picked one up a generic single-side A/R saphire crystal from Krysworks for about $70. They sell non A/R cyrstals for about $45. Send it to Cheif and get it double A/R.

triplehd Posted April 6, 2008 Author Report Share Posted April 6, 2008 Edit to the post above - Krsyworks only has flat crystals that measure 2.5mm in depth. Their domed crystals only measure 2mm. Another option is to PM the dealers. Quote Link to comment Share on other sites More sharing options...

ryaku Posted April 6, 2008 Report Share Posted April 6, 2008 Many thanks triplehd, did you buy a flat crystal? If chieftang agrees, i can buy it get it shipped to him and then get it coated. Quote Link to comment Share on other sites More sharing options...

Do you guys have any idea where we can source one of these domed crystals? I tried andrew but he says he cannot get them. Any other ideas?

triplehd Posted April 7, 2008 Author Report Share Posted April 7, 2008 Many thanks triplehd, did you buy a flat crystal? I bought one flat for my Omega Qmatic - it's an 21j movement from Silix. The original crystal that came with the watch was flat. So, no worries about swapping it with a sapphire flat crystal. Just got me an 21j Omega SMP 2254 (damn Angela from Ioffer couldn't come through for me). I bought a single sided A/R crystal from Krysworks for the watch (if it was ETA - then it would have gotten the double A/R treatment from Cheif. Do you guys have any idea where we can source one of these domed crystals? I tried andrew but he says he cannot get them. Any other ideas? Try others like Silix...... Jules Borel has sapphire crystals that 30.4 in diameter and I beleive 2.4mm in depth. Quote Link to comment Share on other sites More sharing options...
