welcome to OF. while we are still feeling the scare of covid19, your post of that rare speedy somehow lightens up our day. hold on to it and never touch anything til all experts here will guide how to treat it. for its value if you are interested im sure you could have googled already and it is not cheap.
Looks good from what I can see with the possible exception of the hour and minute hands, which may be replaced or re-lumed. If you can post photos of the inside of the case-back and the movement serial number, we can also check that for you.
So all-in-all, proceed with investing into it I’m assuming?
You have to source a matching crown.
I am right to assume the watch still has its original crown?
Yes, it should be a 24-tooth flatfoot crown I believe. The OP would need to show a better photo, although it does seem to be a 32-tooth crown. There's nothing wrong with having an authentic service crown on the watch. Just a matter of taste for a given collector.
