Hi Everyone,

Over the last few years, I've been getting more into watch collecting and have been gravitating towards more of the vintage watches just based on my own personal tastes. I want to educate myself in the area of vintage omegas and was wondering if the community could help me validate if I have an understanding of this particular watch I have in my collection.

I picked it up a little while ago when I knew a lot less so I'm not sure if everything matches up time period wise and to the originality of this watch.

With that being said and from what I've seen in and on the watch, this is my understanding...

Year - 1950 - this is based on the SN - 12573702
Movement - 351 automatic
Case back - 1258028 This is where I get a little confused - Is this another SN or is this another stamp that the case back has on it?
I think the name Ross means that Ross made the case for the US and it's 14k gold filled.

Does anything else stand out information wise or am I accurately understanding all of this correctly? I'm here to learn so any information is helpful.

The movement was imported to the US where it then was locally cased by Ross. You should be able to find more info by looking up the OXG import code which is stamped on the movement. Case and movement serial numbers aren't the same and won't match. Date the watch using the movement serial number as you've done; 12 million is approx 1950. You can use the reference number "6266-7" off of the case back to search for other similarly cased watches.

I think your understanding is correct. Ross was US case maker they made many pocket watch cases for US companies like Hamilton, Waltham etc going back to 1920’s or so. Nice looking watch

Just to add that the numbers inside the case-back are reference and serial numbers, but not necessarily aligned with standard Omega reference and serial numbers. The national case-makers often used their own numbering systems. In some cases (e.g. Dennison) collectors have accumulated a fair amount of information about that casemaker-specific info.

Thanks everyone for all the information! This is really helpful and gives me some things to research and learn more about! That's good to know about the case back and now that I know more about how the watch all came together that makes sense to me. If I learn anything more about it, I'll be sure to share, but overall seems like it is what I thought it was haha 😀.

The reference number is 6266.

Note that at some time the winding weight/pendulum was/is rubbing heavily against the case back.

I had suspected that, but I was basing that off of how common it is to see that with these types of watches. Is there something in the photo that gives it away or is easy to identify?

Thank you for letting me know! It was not running very well when I got it, so I actually am looking to get it serviced by a watchmaker who deals with omegas locally to me. It was hard to find someone who does this kind of thing. This is kind of a trial run/learning for me on who can fix these things, learning about what to look for as I start to be more interested in purchasing vintage Omegas. 😀

You can usually tell by just looking. Omega/watch manufacturers typically make their dials by pad-printing. This means their text is always REALLY consistent and has sharp ends to their letters/etc. Spacing on things is also very consistent. Things like minute markings are typically perfect.

When they do a redial, someone is often just copying from a picture with a pen or paint brush. This results in uneven spacing, inconsistent line lengths and widths, and round ends to lines. Also, they are trying to place indices by pushing them around a bit on top of some glue, so less good ones show the indices not being consistent.

On this watch, the word 'Omega' clearly looks like it was drawn with a pen. The spacing on 'automatic' is inconsistent. The minute markers are inconsistently shaped and placed (some even at funny angles!). Indices aren't perfect, but are a little wonky, particularly 4 and 10 to me.

Okay that makes sense! I see what you mean. I really appreciate all the information. I also found the pinned post about what to look for which also was helpful! Not a particularly great redial, but that’s alright 😀. You live and you learn.

If the rotor is rubbing. Could be a worn jewel in the rotor bridges. Top and underside. Watchmaker would need to check it out.

Can check by turning watch face up with back off, but place hand under the case just in case movement is missing a locking pin (would be opposite of the movement clamp on edge of movement) and see how much the rotor sags

Thank you! I'll try and see if that works before I go and get it fully serviced with an overhaul like I've been quoted so far.

Another thing I was curious about with this watch... Is it common for the crown to not have the omega symbol in this time period? I've read mixed things online on if omega was putting the symbol on them at the time or not. It seems like a grey area, but thought someone here might know.
