Help Me Identify My Grandpa's Vintage Omega Automatic

Hello,

I recently inherited an Omega Automatic from my Grandfather. I don't have information about when he bought it, but it has been at least 7 years since it was last serviced. I plan on taking it to a watchmaker, at least to get a basic service and a new crown. I will also have the watchmaker find the serial number so I can get additional info, but I don't have the tools to access that information at this time.

The watch works! I did some quick tests and the watch does appear to keep time well. When I shake my wrist, something in the watch moves back and forth within the case, not sure if this is normal for vintage watches.

I am looking for information about when the watch was made, what the model number might be, servicing / maintenance advice, and ballpark valuations. Also if you have anything interesting to share about this watch or vintage Omegas like this one, I would love to learn more!

Thank you all in advance!

Very nice watch to get from your granddad. Don't know much about this but if you feel something moving inside its probably an omega bumper movement. Get it serviced and enjoy. Good luck.

The movement inside is a bumper! Thanks for that tip, I can definitely feel something moving around on an axis and bumping against springs.

I agree that the dial appears to have been relumed but awesome watch to inherit nonetheless. Wear it in good health and congratulations!

Definitely relumed at some point. These rail track dials don’t exactly grow on trees and yours is a lovely and well loved example. A friend of mine had a very similar dial not too long ago (though it’s younger than yours, with the Seamaster script), but this is how the original lume aged:

here is my 2577 bumper cal354, gold capped/jacketed case

I concur with the above, service, crown replacement and enjoy. Yes it appears to have been relumed but it’s a hand me down so it’s not going to be sold. Enjoy.
