PreMoon 145.012-67 SP inherited from my father - need help understanding configuration

EricB · May 27, 2026

Hello everyone,
I inherited this Speedmaster from my father and I'm trying to understand its history before considering a restoration.
Any expert input would be greatly appreciated.
KNOWN HISTORY:

My father bought it during his military service in Germany, most likely 1968-1969, at the latest very early 1970.
He had it serviced at some point (date unknown) but I have no service records.
It has been sitting unused for many years.

WHAT I CAN READ ON THE WATCH:

Caseback: 145.012-67 SP, HF hallmark
Movement: serial 32857543, signed Omega Swiss, 17 jewels
Dial: OMEGA / Speedmaster / PROFESSIONAL / MARK II, T SWISS MADE T at the bottom
Hands appear to have tritium lume aged to beige/honey

MY UNDERSTANding (please correct me):

Case is original 145.012-67 SP, consistent with a 1968 delivery date.
Movement serial ~32.8M points to ~1970-1971, suggesting this is NOT the original cal. 321 but a replacement cal. 861 installed during a later service.
"MARK II" on the dial is not standard for a 145.012 - it looks like a service dial from a 145.014 Speedmaster Mark II was installed at some point.
Hands likely also replaced during the same service ?

QUESTIONS:
1. Can you confirm the movement is indeed a cal. 861 from the photos?
2. Is the dial confirmed as a Mark II service dial, or could it be something else?
3. Are the hands period-correct service replacements, or later still?
4. Any guess on when this service intervention took place?
5. For someone who wants to bring the watch closer to its original configuration, what would be your advice - leave as-is (honest service watch), or hunt for correct parts (cal. 321, correct 145.012 dial, hands)? Photos attached.
Happy to take more if needed (specific angles, macro shots, etc.).
Thank you for your time and expertise !!

Questions:
1. Yes cal 861 doesn’t belong in this case
2. Yes Mark Ii dial doesn’t belong in this case
3. Hands period correct
4. Who knows?
5. IMO leave as is it will be tough and expensive slog to buy expensive parts 321 movement and correct dial. And it will still be a put together watch not original. Just get it serviced if you want to wear and enjoy your father’s watch as he saw it.

It probably had water damage to movement and dial prompting this cobbled together service.

Or possibly he bought it used in this condition?

Yea that looks like a parts watch at this point, some decent value in the parts mind you, but best part it out imo

SOG53 · May 27, 2026

A movement service will cost around $1000 maybe more depending on parts needed. That’s minimum cost to get it wearable. Alternative is sell as parts as Ash suggests above. Depends on how attached you are to it.

EricB · May 27, 2026

Thanks a lot for your replies !!

@SOG53 : he bought it new as far as I know. but he lived in a tropical country. That's probably why it was serviced once or twice and had water damaged. There are somme notes in the case (on the left and down).

@dsio what parts are the most valuable IYO.

I think I will have a movement service and keep it. Sentimental attachment 😉 my father passed away one year ago.

Do you think I should have a "omega service" or a vintage service to keep it as close as it is... Asking even though I think I know the answer ! Any advice of what to do, and not to do regarding this service ?

thanks again guys

Omega will replace everything and cost thousands. Not recommended.

Find independent watchmaker with Omega parts account and ask for movement service only. They will guide you regarding what parts need replacing.

Share your location if you like recommendations.

Good luck and feel free to share “post” results.

Depends how much you're willing/able to spend : )

Here's something to consider but not advice.

An Omega service is more expensive. The bennefit to an Omega service is a two year warranty and they replace many parts as part of the service.

However, Omega may not service it if they think it is put together. They will likely give you service hands and a service dial if they will service it. Plus they will likely replace the pushers. But they return parts so you could potentially put the old pushers back in. That would void the warranty and make it not water resistant.

There's sentimental reasons for keeping as your father wore it. But, what would your Dad do? He got it serviced and fixed so he could wear it. It seems that your Dad would not begrudge you for getting it serviced with newer components.

You might want to discuss it with Omega first. Here is contact info for the Omega Service Center in Seattle. Debra Allen, manager. 206-624-400. Email [email protected]

You may not be near Seattle but she can probably tell you what a service center would do.

Hope this helps some.

I think the question is what would they turn it into, given there isn’t a 321 serial id imagine it would end up as a Mark II if the movement matches the dial.

That would probably be the best outcome imo, selling the case and bezel, keeping the movement dial and serial as a nice Mark II. I can’t imagine Omega will supply a new 321 and serial at this point

Definitely not. You're right on the money though. What would they consider it. Would they agree it was originally purchased by the caseback? They typically give more weight to the movement, so as you say, might treat it as a marrk II. I suspect they won't want to service it. But you never know. A sympathetic manager might respond to "my dad bought this in the military."

Edit: to me, the most important part of the watch is the case. His dad had that steel case against his skin, with that skin smoothing out the steel over years. Those nicks and scratches came from a lived life. That's what makes a family heirloom.

Agree. That’s why I would just service movement and wear as is

I can only agree with this, and don't forget the dial - that was how the watch looked when he had it, and how you have it now!

THIS!

It is not worth looking for a correct movement, dial etc,
and TBH - no one outside the "Speedyworld" will notice the difference!
Trust me.....

Tough one. It’s pretty much a hybrid but as has been said, the serial number is almost certainly a replacement so if Omega used that for identification you may well end up with a mk2 which isn’t what your dad originally bought.

Personally I’d find a good independent watchmaker in your country, get the movement serviced, case cleaned, retain the dial and hands but get them relumed.

Then you’ve restored the watch to how your dad likely had it from c 1972 onwards.

Looks to me that it is as simple as a MkII internals placed into a 145.012 case.

So you could go ahead and make two watches, a Mk II and then source a movement and dial and hands for the 145.012.

You have a good DO90 bezel there.

The MkkII case should be relatively cost-effective - I often see complete cases with Crystal and pushers and crown, sometimes even a bracelet for around $600 (some less some more).

Of course the 321 movement and dial are going to be a lot of money - unlikely to be cost-effective, but satisfying. Also, the hunt is fun, and you might get lucky

That's funny because I was also thinking of "making 2 watches" out of this one 😀). On top of the cost of a 321, I feel far too much of a novice to risk buying stuff on eBay. It seems like a jungle out there, with lots of counterfeits 😀

Also, I'm less of a fan of the Mark II's aesthetic vs. the Moonwatch. And finally, I do think it's better to stay faithful to what my father wore.

My only regret is that, back then, the watchmaker who repaired his watch paid no attention to authenticity. But I guess that between 1970 and 1990, people cared less about it, and movements were swapped out the way you'd swap a circuit board today.

thanks to you all for your comments. it really helps !

Maybe contact Chronoglide in The Netherlands about servicing or restoring it : https://www.chronoglide.nl/contact/

Of course, you could just service it and clean it, straighten the bezel and enjoy the watch for what it is, a product of its experience and its owner.
