Omega Symbol on Crystal

·I have to agree with gator, I'm sitting here with a c-case Constellation with a cyclops crystal and the Omega symbol is 90 degrees off, so clearly if Omega didn't care if they were made with the symbol oriented "correctly" I doubt they were all put on lined up perfectly either.
It's 135 degrees out on the cyclops crystal on my sparkly.

·Reviving this thread......
Is the Omega mark on the crystal still being put on modern watches? I can't find much on it. I looked at several recently and cannot see the marking, nor can the jewelers I was working with.

Short answer is no, except for some Speedmasters which still use a Hesalite (acrylic) crystal. Sapphire crystals do not have the Omega symbol.

··Omega Qualified WatchmakerI know this is an older thread, but just to put a couple of things to rest here...
1 - Omega does not line up the logo in the acrylic crystals, but they do pay attention to the crystal alignment. They line up the split in the tension ring so that it is on the lower portion of the watch dial, and is less visible.
From Omega Work Instruction 14:
"The OMEGA logo does not have to have a special orientation for hesalite glass."
And:
"The armoured ring slot must be between 25 and 35 minutes."
So that should put to rest any theories that original crystals will be lined up perfectly - if they are lined up it is either random, or likely installed by a watchmaker that isn't working at an Omega facility (I always line them up, as I know my customers would want this). Of course with the sapphire crystals, there's no tension ring, so they would line them up I would expect.
2 - The logo did change over time. Not sure how many variations there are, but here is an older stamp in the crystal:
And here's a newer one:
Hope this helps.
Cheers, Al

Thanks for the info, but I'm a bit confused. Are you saying that there should be a mark on all crystals? Because an earlier poster said that it is not used on sapphires. Just want to be certain I've got my facts right. Thanks again.

Please red the post directly above the first one I made...

·I just watched a video made by Bob's watches they states more than once that only hesalite crystals were signed. That's the first time I'd heard that. They didn't mention when they started signing crystals, which was what I was looking to learn. I've added the link at the bottom of my comment.
I just bought a NOS Seamaster from 1952 and there's no logo on the crystal. This watch has a seal on the back that is centered on the case back perfectly and looks original, but I'm not sure about that either. There's like no wear on this case or crystal. I've never seen a NOS Seamaster from this era and it checked off the gold Seamaster and waffle dial boxes.
I have several Seamasters from the 50's and 60's and there's not one signed crystal amongst them. I have no idea if they were replaced, many had scuffs and tiny scratches that I polished out.

··Oooo subtitles!Many Hesalite crystals weren’t signed. I’m not surprised to see an early 50s watch without a logo. There are signed sapphire crystals too. I suppose they meant that there are no mineral glass crystals with logos. That is AFAIK true. I suspect the logo crystal was introduced around 1952-55 depending on model.
What you show there isn’t a seal, it’s a modern caseback sticker. If you have 60s Omegas without crystal logos, they are probably non omega crystals.
