The Late 1950s/Early 1960s Omega 520 Thread

I keep an eye out for Omegas with 520 movements here on the Forum, but few seem to appear. Is it both uncommon and unloved?



The Omega 520 Seamaster here is a shameless hussy, sporting a re-dial of that dial style. An Ebay purchase, I acquired it not long before joining the Forum and becoming wiser to the ways of redone dials. At the time I got it I thought the dial's styling design was appealing and didn't know any better. The watch itself is a hit with the "great unwatched" who are igonorant. It's about the only watch here that garners approving looks and comment: "OOOooo... an Omega!" while the decent examples go begging for attention.

The movement is a bit different. This one's always sounded loud, like wearing a threshing machine on the wrist, but it's regularly serviced and keeps excellent time. Apparently the movement was a Marc Favre development and was acquired when Omega acquired that operation in 1955. The 520 and its near kin the 510 were only produced by Omega for a few years.

Reverse side of the 520 here.


Do any Forum members here have any Omega watches with 520 movements? It's easy to look up images on Google Images, but I'd enjoy seeing any member's watches still featuring the original dials.

I don't have an image of my watch's movement, but here's an Omega Forums image of the movement gleaned off of Google Images.


Here's the thread. The hands on the watch shown are different than mine as is crown and back.

I too heard the story about the Favre Leuba facility buyout. I had this manual wind fat lug which used the 420 which I believe is part of the same family. Judge for yourself.

Thanks for posting the 420 movement. It bears a family resemblance.

That's an appealing watch with styling which I appreciate.
