Printed logo with long indices and steped.

 

I'm looking at my 3572.50 and it looks like that? Kinda new here, so take my word with a grain of salt.

 

Welcome and not exactly if you look at Lume indices on the dial, you will see that the ones on yours are shorter and yours does not have a step

 

Oh wow, I was looking at the length of the indices coming towards the center, not going towards the bezel. I Haven't had my coffee yet.

 

What do you mean by steped?

 

the "premoon" Speedmaster Dials have circular step near the end of the PRINTED minute incides

What movement is it for? I've seen it on the 321s - assumed as service dial.

 

I thought it belongs to the Transitional period and was fitted on 861, but i dont know for sure

 

Depends which calibre it is for. I have seen enough painted logo dials with 321 feet to be reasonably sure (Not certain!) that Omega manufactured a dial with a painted logo for 321's with this layout.

Do you have a photo of the back?

Here is what I believe to be a service dial. Note the T marks and painted logo, and long indices. This one differers from the OP in that it is a Non Pro marked dial:

 

And to confuse things further, this dial arrived on a watch that had been fully serviced by Omega - so the owners nephew assured me, and the dial has now been removed and checked - it is indeed an original equipment dial with 321 feet.
Please excuse the poor photo, it was just a pre shipping record and I dont have a better one but you can see the important parts:

 

Your dials look more like modern replacements, maybe 80ties, because they bothe lack the step, if i didn´t miss anything.
The one i posted has a clear step as the old ones have. Maybe its a service dail from the early seventies.
But to be honest i have no idea for which movement it could have been used. I know that i have seen one of these dials in a 145.022 somewhere in the internet, but i cant find it anymore.

 

Well the first does have a step, and close marked "T"s.

The second I am not sure as it is not with me and I only have that crappy photo - but the oral, (thus unreliable) history was that it was serviced by Omega in 1960's.

I think there is more to the service dial history than first meets the eye.

 

still gotta have the original. I know there were service dials which looked like cal 321 feet but with painted logo front. Not very common at all but they are out there
