Omega

I've seen a couple of vintage Cosmic Omega watches for auction. Does anyone know of the big square ones reference 3903 to be produced in Stainless Steel with a black dial?

If it is the watch which is currently on auction - forget it! It is not original - this Ref. should have a plain automatic bumper movement and NOT a cosmic calender movement! So be carefull! best erich

I've only seen solid gold ones!

The Omega vintage information site shows only one rectangular Cosmic version and this is the ref. 3944. It was built at least in 14K and 18K gold. There is no information about other case material. But as always with Omega: there are many facts we don´t k... 

Hi Everyone... i do not know the auction your talking about... Here is a pic of a watch i once owned years ago.. it had a 342 movement... Omega actually used this case with the addition of 3 adjusters for the Cosmic and changed the ref. ... I have seen ea...  

I saw that watch shortly after it was listed and I second the observations already made - looks like a put together piece; I would not consider its purchase at all.
