Replacement Movement for 1970's Constellaton f300hz?

Hi everyone, I'm writing in an update. I'm very happy with the resolution of this post and I'd like to share the whole story.

I bought this watch from someone on eBay for $550. The seller said it was an old watch that might run fast or slow at times. Actually the watch movement was in much worse condition than his comment suggested. Oh well. Caveat emptor.

I took the watch to a certified Omega repair person in Texas. He looked at it and said it needed a lot of work. At least a new movement, and possibly more. Because the model was so old (1971), finding parts would be difficult or impossible. The upper range of cost for a hypothetical repair would be so high that he did not want to say a number.

Months later, I was going to New York, so I took the watch and left it with another certified Omega repair person. He gave it a good look and said it needed a new movement. I would have to find a used movement and frankenstein it into my watch. Finding that would be hard, and more expensive than he could safely estimate.

At this point I decided to eat the loss and sell the watch to someone else with the means and resources to fix it. I had the watch listed for sale for $300. I explicitly said in the listing that the watch is not running properly and needs a new movement. No bites on the sale.

As a last ditch effort, I put my original post on this forum. I got all your responses with solid recommendations for people who could fix the watch. I first contacted Rob Berkavicius. He responded right away. He was knowledgeable, professional, transparent, and gave clear instructions on how to send the watch to him. His attention to every logistical detail was impressive.

Rob looked at the watch and quickly diagnosed the problem. All it needed was a servicing. The movement is fine! All together the repair with Rob was about $150.

Now I have in my hands this awesome watch, running perfectly. I could probably sell it for $1,000 to $1,500. But I say no deal! It's too sexy to sell. I can't wait to put a strap on it and show it off.

Thank you to Rob, thank you to @watchyouwant and @Boojumhunter for recommending Rob, and thank you to everyone else that took the time to give helpful advice. You guys rock!
