Do you have a photo of the inside of the caseback? That's where the reference number should be.

Okay. A photo would be far more helpful. Someone is going to recognize the movement.

@mac_omega told you EXACTLY what reference it is. He is a highly regarded expert.

I am not shy to correct my own statements - obviously I have made a mistake myself...

The wrist watch of the OP is pretty small and the case design (lugs) is the same as on the ref. 2144

As the watch has a center second movement encased in the same case style of 2144 it might deserve a different ref.# maybe 2145 or other 214x ?

There is a ref. 2143 in the data base which has the same case and movement as 2144 but does not have chronometre rating and hence no chronometre inscription on the dial.

Only an extract from the archive will shed some light on this topic and hence we would need at least the movement serial#
I am pretty confident that there is no ref.# in the case back, only a case serial.

Let´s wait and see.
Only "30" is stamped. Not sure if that's a serial number but it's certainly not a reference number.

There seems to be some discrepancy and confusion and varying points of view, I dont have a problem, this is not my world so its all jargon to me. Sorry to trigger a tonal disorder I am a novice here

Can you advise where to from here, this is all very daunting as I am not familiar with all the jargon or where to look for this information, I have googled to death but am not finding much. I have been told you are an expert, your assistance would be greatly appreciated. Thank you. Laurel

I would make a semi qualified guess regarding the movement. It seems to be R13.5 SC. Odd (or maybe not so odd regarding the period) is that there is no chronometer marking on the movement. But the movement seems to be of a better finish than other R13.5 SC you can find on google. And if you believe this guy http://thewatchguy.homestead.com/pages/OMEGASERIAL.html
movement was made in 1939. Omega also states that 9mil case numbering started in 1935 and 10mil started in 1943.
You could maybe ask the watch maker to look under the balance wheel to see if there is some number and if so what it says.

It does make me laugh sometimes that people come here for help with absolutely nothing, no knowledge, no information, having done no research themselves apart from finding OF on the internet. That they sometimes then become impatient with the speed and accuracy of what they are being told never ceases to amaze me.

The assistance that you are asking for is being provided in buckets, sometimes things are not quite so clear or clear cut as you would maybe like them to be. That is the world of vintage watches and how earlier the production generally how fewer the number of ´experts` qualified to reply. I suggest a bit of patience as there are no other places where you will find better answers than here.

completely patient, just very confused. I would assume a forum of people in the know would be the first place to glean information for the inexperienced.

It is but the experts on this board are all over the world. Not everyone is in your time zone or spending every waking moment waiting for yet another question about a noob's Omega. Give them time to respond.

You are correct an Omega Forum is for sure a good place to begin. But don't forget most people here also have a real life and real work, your appealing for more answers to your questions only an hour after posting the requested pictures could certainly grate on the nerves of the people you are appealing to for information. Just friendly advice. 😀

And remember that there are literally thousands of wristwatch models/variants produced by Omega, and that your example is 70+ years old. If it was something from the 1980s (for example), then you could probably get a completely correct ID within minutes. Something like this is much more difficult, even for those who can be considered experts.

Who opened the watch? And who scratched the case back
