If you go for an original condition vintage model do remember that unless the dial and hands have been replaced there will be no life left in the lume.
Other than that a well maintained Speedy will be fine as an everyday wear. Remember to budget for a service maybe every 5 years or so. If it has the Hesalite rather than sapphire crystal you'll probably want to get some Polywatch to polish out any scratches.
Hades, just bear in mind that a lot of the value in vintage watches is tied up in the originality of them. If you buy an original speedy pre-moon and then have it serviced over-zealously it could well devalue it, as they may polish the case too far, replace hands etc. Its the original patina which gives the value. You certainly couldnt polish the hesalite too much, or replace the case back without it losing something of what makes it valuable.
Thats what I was thinking when I said bin the birth year idea. Id happily wear a vintage watch, but I wouldnt want that as my daily beater given all the imperfections, scratches, dinks and issues with lume etc.
Good luck in the speedie search. There are plenty about so you shouldnt have a major problem finding one, and they start at £2.5k new so should eaisly be in price range.
