Need help please

Got this watch back cover from my Watch collection that I picked up years ago. It’s got 510 C DD on the back .

It’s of the moon landing

But don’t now what watch it came off ? So need some help in identifying the watch it came from if anyone has any suggestions please let me now thank you.


No idea I'm afraid, but it's one of the coolest I've ever seen.

Good luck 👍🏻😍


Thanks for your help in identifying the watch back Great 👍 Cheers
