Building a 105.012-65

So the mission begins... picked up a 1966 321 movement with a production date of June 13, 1966 that is less than 300 from Neil Armstrong's serial number so very stoked. It was completely overhauled by Omega in 2018 so looks pretty much new and I currently have it living in the new Ed White set-up (literally the complete watch with this movement instead of the new 321) as I source original vintage 105.012-65 parts. So far I was able to acquire the correct HF case in really good original condition that has one of the original fat neck pushers still installed so consider than an early victory.

So the mission begins to source the remaining parts to put the movement back in its original home. Any insight on where to source older vintage dials, pushers, crowns, and case backs would be greatly appreciated (other than ebay which I have alerts already set-up on). Bezel and hands I may just go with service parts as I do plan to wear it often. Did find a DON ceramic bezel that was on the Silver Snoopy so that could work well.

Open to any advice from the experts on thoughts on what to keep historic original (assuming I can actually locate the parts) and what to keep practical as a watch that will be worn regularly. Not concerned on resale value as with all my watches I do not sell them.

Photos of the movement and its current home for the time being.

personally not a big fan of recreations like this. When your project is completed there will be no way for a potential buyer (and there is bound to be many down the road) to tell that the watch is put together and that the movement never originally came from a Speedmaster Professional especially with the archives now closed...

I am not sure what you mean as this is not a recreation. I actually have the extract of the archives that shows the movement is from a 105.012 ( I did note the exact date of production in my post) so the movement came from a Speedy professional. Also, I noted that this will never be sold as I noted in my post I do not sell my watches.

The original post did not say that you had an extract. That changes things. Do you know how this movement came to be orphaned from the rest of the watch. You said it was serviced in 2018, Omega would not service a movement without it being part of a whole watch, what is the story there?

Apparently is was discovered by a family member in 2018 in the belongings of a past member so they sent the original to omega for service. They restored the movement but replaced the dial, bezel, hands and polished the case. It was then sold and the person who bought it sold it for parts with the extract staying with the movement (I tracked down the person who parted it out).

The dial will be the most difficult to find as It was a specific closed T variant (around 4000 watches produced with it).
