iEdi's detailed inquiry into a vintage Omega Speedmaster Ref. 145.012-67 SP offers a masterclass in evaluating the authenticity and condition of historical timepieces. His questions about dial patina, case-back markings, and restoration ethics remain highly relevant for collectors navigating the complexities of the vintage market today. This discussion underscores the enduring value of original components and informed decision-making in preserving horological heritage.

Hi !

Just a few pics and some questions. Enjoy the pics and please tell me what do you think.

And the questions part

1. What do you think about the condition of the dial and hands ? What I mean is that I have never seen before a 145.012 with such a nice patina on the dial...

2. Very important : what do you think about the case-back ? As far as I know the ref no. should be "145.012- 67 SP", but here "67" is missing (the serial number on the movement is scrambled and I apologize for that, but it places the watch in 1967 for sure). And what is the meaning of the stamped "3" , "4" and "MH" ?

3. What do you think about restoring this watch ? What I mean is that as far as I can see, most people are restoring this kind of watches (new set of hands, new bezel, new case, new see-thru case-back), but I see a blasphemy in modifying the original design.

4. I'm really considering just a movement service and I want to let the external parts untouched (with all the signs of time on it, including the scratches). What do you think about that ?

Any input will be of great help.

Best,
Eddie

Key Points from the Discussion

The aging process of lume on dials and hands can differ, raising questions about whether tritium absorbs color from the dial or if application methods vary between components.
While the dial appears original and well-patinated, the hands might be later replacements due to their unusually good condition, a common occurrence during factory services.
The case could benefit from light scratch removal and gasket replacement, but drastic polishing should be avoided to preserve the original Speedy logo on the case back.
The composition of lume, including tritium, phosphor, and binding agents, likely influences color change over time, with oxidation potentially playing a role.
An extract from the Omega archives is invaluable for confirming the originality of the movement and case, adding significant value to the watch for future resale.
The question of whether tritium on the dial patinates more rapidly or differently than tritium on the hands, or if it absorbs color from the dial, is a key point of discussion.

That I know nothing about Speeds... But I wouldn't touch the dial, as the Patina is maginficient. It gives a lot of warnth and charm to this Speed, IMO, and I don't see why it would not be authentic. But my knowledge is very limited on Speeds. Best, Nicolas

I wait for the others to comment on it. Allow me to say that I'm not worried about it's authenticity (is very clear to me that is authentic), I'm not worried about anything, but I'm very curious about what I have asked.

the dial is nicely patinated and looks original, very well looked after. i would leave it exactly as it is. it is possible its a replacement early on in the watches life so that its patinated, but in such good condition. something you;'ll never know. the hands look too good and are probably later replacements during a factory service. the bezel is good and should be left. the case outside would benefit from a very light scratch removal and the old gaskets cleaned off and replaced. nothing too dr

Thanks a lot Graham ! That's a very complete point of view and is of great help. I was thinking about the same, except the light polish and the replaced hands. The hands must have been replaced very early, as they are showing some patina. About the numbers and letters written on the interior of the case-back I don't know what to think, but I think you are right. The movement will be serviced indeed. Kind regards, Eddie

they look very white. i cant upload pics at the moment or i would show you my 64 speedy which is only 3 years older. the good thing is that the hands didnt change from your model all the way through to today so even if they are newish they are correct. best Graham

you can see that the white is darkened and the lume inside it is much darker. original or replacements, your hands are correct for the model which is by far the most important thing. best Graham
