·I have a 105.012-66 HF and a 105.012-66 CB and the dot of the 120 seems to almost line up with the 6 hour marker
Edited:
DON bezel... wrong position of 120?

·Just to level set (telling myself as much as anything): if a vehicle goes exactly 1 mile at exactly 120mph it will take exactly 30 seconds to do so.
Anything else on the dial/bezel should be an error of the dial/bezel.

·On my 68 Transitional Speedy, the DON Bezel shows the 120 on the right edge (or just inside it) of the 6 o'clock marker.
I've seen this same alignment on several DON bezel pictures on the internet.

If yours is off, it’s off by 1/5th of a second. That seems to be about the error tolerance for these dials in terms of how perfectly (or imperfectly) the lume is applied, etc. if you look closely at these dials, the loom plots can be off center almost the entire way around the dial (and inconsistently) - and this is true of even the modern dials. Here is a picture of my SS cal.321B:

Have these pictures from a recent thread where we found that these uneven placements of the lume go all the way back to the original Ed White (two different examples below):

·That’s pretty much the amount they are all off, when they are off. Assuming the OP’s dial is slightly torqued clockwise, it would be off approximately this amount as well, no?
Not really an exact science to it, but the OP watch appears the 0.5 sec off he mentions. But maybe more strange about the OP is that it’s not just the lume plot that’s off but instead also all the sub-indices near 6 o’clock, but not at 12 o’clock?
maybe better pics will say otherwise

·Below are pics of (in order):
A Hesalite 3570.50
A Sapphire 3573.50 from 2007
A Sapphire 311...006 from 2017
These helpful in showing both range (type, age) and also because the lume plots don’t extend through the sub-indices.

Note that it’s off in the other direction compared to the lume plot, but the lume plot itself is the item out of kilter

·Hello everyone,
I have been observing that there are DON bezels that have the 120 offset from the 30 .. my 105012 66 CB has it around the 29,5 minute. Was there a manufacturing fault?
Thanks
I expect tolerances, yes. Is that the answer, you are looking for? Kind regards. Achim

If they are the usual tolerances...great!

·Hmmm, both the dial and the bezel appear to be out of whack 👎
In addition, the dial is oriented according to its 2 anchors to the movement, and the movement according to the crown in the case...

··Pratts! Will I B******S!!!Over time, it's not surprising that some small percentage of vintage bezels are going to be off a bit from expected tolerances. Let me offer an explanation grounded in astronomic terms - as is only appropriate for the so-called "Moonwatch", recognizing of course that the OP example is actually a "pre-moon" example.
Basically, the universe continues to expand. However, local gravitational influences can distort the relative changes on a micro scale. Slowing, varying the expansion across short distances or even in some cases reversing the expansion. Hence the slightly different spacing of the markers on one section of the bezel vs. another, and in relation to the dial. Don't be confused by the relationship to the hand set - they are influenced further by being in "orbit" relative to the fixed dial and bezel.
p.s. This thread is a fantastic example of why the WIS-erati are looked upon with wonderment and awe by "normal" folk. 😜

I have no clue what you’re saying, but here’s a picture of OPs watch oriented to the central and lower handset as center 😁

Here’s one oriented to apparent center of the sub dial’s “6” and the hour lume at 6 o’clock, followed by one oriented to apparent center of the dot over 120 on tach
finally, a wrist shot, oriented to @Darlinboy ’s comments

·As the lume plots represent three sub-indices or 2/5ths a second, it seems to me that OPs misalignment is itself 2/5th a second
If, for example, Omega’s tolerances on these dials and bezels is 1/5th a second, then OPs watch could simply be a particularly matched combination of the lume plot tweaked clockwise by 1/5th and the 120 mark tweaked counterclockwise by 1/5th

·The OP's watch definitely appears to be farther out of alignment than is typical. As cvalue13 says, perhaps just a victim of the 1/5th error rate occurring on both the dial and insert to compounding effect.

·I suppose at a service the bezel could be adjusted just so to split the difference between the 6 and 12 o’clock positions, and blend/minimize the effect
these things have a tendency to not be unseen, and the above tweak may alleviate
