·You know a lot, DON, I just have a different opinion on this one. I feel it's original and degraded. Fonts/printing are good, sub-dial sharp including snailing, etc.

A small second has 2 reference points to scope it with crosshairs for orientation. No need to notch it. However. Someone who is used to notching dials for refinishing would do it automatically as its second nature to do it.
Some numbers also sloppy.
Again. My opinion.

·Dear Mr. Don,
I understand your point regarding the mark present at the 12 o'clock position on the dial.
However, I do not believe that this is a refinished dial. I will take better photographs of this detail and remove the dial so that we can examine the back side as well.

·I also vote for original. You cant really ,,produce,, such a patina. I like the dial!

·Another question:
Have you ever had any dials from this exact model in your hands, outside of the watch case?
That would help us determine whether this mark at the 12 o'clock position is normally present or not.
Since I only have this example on hand, I cannot make a comparison myself. However, I will do some research on the internet.
I will also remove the dial to examine this mark under a microscope and inspect the back side of the dial.
I believe that if this mark was made by someone who refinished the dial decades ago, it was probably made with a file or a similar tool. Therefore, the tool marks should be different from those left by a factory stamping process.
That is an analysis I intend to carry out here.

Regarding the mark at the 12 o'clock position,
I believe it is factory original.
Now, this is merely the opinion of a mechanical engineer.
For the positioning of the dial, even with a sub-dial present, I would expect it to be referenced from the central hole because of the existing locating fixture. Making a fixture with two additional reference holes, when there is already a somewhat "universal" alignment device available, would increase the complexity of the process and make manufacturing more difficult.
But, as I said, that is only an opinion, and I prefer facts.
I do not have any knowledge of the Omega dial alignment process used in industrial production during that period.
I will attach some of my other dials for comparison.

·Notch at 12 on dial edge.
I’m of the mind that if the dial is notched. It’s refinished. A sweep dial would need to be notched to orientate the dial as there is no reference points to tell you which way is up once the paint is removed.
A small second has 2 reference points to scope it with crosshairs for orientation. No need to notch it. However. Someone who is used to notching dials for refinishing would do it automatically as its second nature to do it.

·Here is a thread I recall discussing notches. @Archer shows some notches on new dials and @mac_omega mentions seeing them on original Omega dials at 12. My feeling is that a notch at 12 by itself is not sufficient proof of a refinished Omega dial, and it is important to examine the dial itself closely.

And post some pictures here to everybody comment.

·OK. I’ve explained why the dial is notched, but never seen a post on why the factory would.

You have a good point.
And i am not a expert on it.
Just an enthusiast
This is the beauty of this kind of discussion.
Collectors and enthusiasts trying to understand something.
I have some dials to look at my shop.
Some I know it's not original.
Others I am not sure.

Mr. Don,
I came across an interesting coincidence regarding the concave marks found on dials at the 12 o'clock position.
I would appreciate your help with this theory.
I noticed that three dials bearing the same mark were all made by the same manufacturer: Z.J. (Zelim Jacot).
Perhaps this is a particular feature of their manufacturing process.
Do you happen to have any additional information about this?
Maybe you have access to more images in your virtual library.
I will attach a few photographs:
One is of my 30T2 dial.
The other is of a Seamaster advertised as new old stock.
I will disassembly my bumper on Monday.
I would greatly appreciate your opinion on this matter.

Thanks for your photos.

I posted in other replay to Mr. Don.
Your's photos help my theory.

Let's wait for opinions

·I think that notch is an original technical notch from the dial manufacturer. A few others...
