Right, another historical question from Smith

We have already established the start dates for copper-plated movements.

We all know that genuine Omega crystals have the little Omega symbol dead centre, like this -



When did this symbol start to appear? Does anyone out there know?

Thanks in advance for your input . . .

 

There was a discussion around this issue here fairly recently, but I don't the thread, hopefully someone else will remember.

I do know that the crystal on one of my 1952 Constellations has an original signed crystal.

 

I also have a question about Omega logo on crystals for the Speedy experts:

Did the early Speedmaster models like 2915 and 2998 already have a logo on the crystal or not?

Thank you in advance

 

Yes.

 

The start of logo crystals would have been in the very early 50's.

 

Thanks for your thoughts on this topic. There is probably no way of being absolutely sure on this issue, other than by finding some documentary evidence from the factory. As Gator points out, there is no way of knowing whether or not a watch actually retains its original crystal, so the best we can do is make an educated guess.

 

Yes it's true but they are not all identical
starting 50's until late 70's we find a kind of logo, later another one, so it is very easy to understand if you have a proper crystal or not on your 2915 or 2998

 

My 2699 came into my possession in mint condition with an omega logo on the crystal which I believe original to the watch.




movement serial # 13.54X.XXX ...

 

What you are saying might be correct.
All you have to do is to look very close at the Omega logo's legs, because the more recents' one are different than the older one.

 

That's called 'happy feet'.

 

With the little help of some pictures it could be easier to explain.

 

Made in China




60's original

 

The "legs" of the symbol are also longer on
original crystals just like on the crowns.
I also have a pet theory I can't prove that
these symbols were lined up straight at
the build and an NOS(or untouched) watch should have
the symbol aligned straight up. I have an NOS 145.022
that still has the wax seal and it's lined up perfect.


145.012

 

Well it certainly makes sense that the factory would have lined up the Omega symbols perfectly. I thought that the example I gave you at the top of this thread was an original crystal. It was on a 1962 Seamaster and it was lined up perfectly. The crystal was also pretty scratched up when I got it, and I spent a pleasant afternoon buffing all the marks out. But now it seems that it may not have been.

Actually, I have a terrible confession to make. When I have had the crystal replaced (as on my black dial 2635 recently) I have specified a generic crystal, not because I am a skinflint but because I am so rough on them. The watches that I wear always seem to get scratched up no matter how hard I try to be careful. I may as well buy the cheaper crystals and replace them often.

 

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.

 

As I said, it's just a pet theory. There are a lot out there though.
And that would make them all coincidences I guess.
I just now did a google image search for NOS Omega
and grabbed this off another forum. Due to angle of photo, symbol is
at 11 oclock. My 145.022 NOS is just like this.

Coincidence?
