I had a conversation a little while ago with a certain Omega enthusiast who was of the opinion they are service dials.

 

Brown dome dials occasionally pop up too - and have been deemed legit on OF - but are as uncommon as the greys

I wonder if they could have been special order at some point (as black dials were originally)

it might be useful to understand when lume inserts were phased out on Constellations - as it wouldn't make sense to make a later service dial with old-style indices

I'm fairly sure they were used on .004s but I can't recall an .010 or anything other than an early 168.005 with lume inserts - they tend to be onyx/painted inserts or solid indices with notches for lume or lume dots (or both black inserts and lume dots in some cases)

@kyle L - any chance of getting the movt no. for this watch?

either way (unlike the browns) it’s a great look

 

In case no-ne has already said it - Dibs Lovely watch

 

Are the white inlays or painted. Have seen a few grey dome dials over the years.

Non as nice as above.....

 

That's lume down the center of markers.

 

How does the movement look like Kyle?

 

@hoipolloi - what do you think of this one?:

 

That one looks like a service dial to me, but the grey one from Kyle doesn't.

 

Not a comment on originality, as I am not versed in these, but the different "M"s on the sunburst dial look very strange.

 

I was going to comment on that myself - the lume in the indices is quite light and 'minty' compared to the hands.
However, here's an early 168.005 I came across in a search (20,99xxx) where the lume is distinctly different in the indices and looks quite aged, so no real reason to suspect a lume job (not quite as minty but if these were against a grey dial they would certainly stand out)

 

I have a 010 with that type of lume on hour markers.


And I don't see anything later than that.

 

Thanks for that Hoi - good to know.
Is it an early one by any chance?
Some of them came with a 561 didn’t they?

 

Yes, it came with a 561 serial # 2445Xxxx.

 

Well that was a lucky stab in the dark.
But it does begin to build a case that the grey dial is contemporaneous and not a later service dial.
