Back from a fresh service! 18k gold. Dial is a bit rough but it runs beautifully. I have the original papers from the sale in Toronto, 1961.
If anyone could point me at a picture of the correct box, crown and buckle, it would be much appreciated. I can't find anything consistent.
Movement picture was taken at a former service. I can dig out an post a picture of the papers if there is any interest.

 

Hi,
I have a complete set 2872 18k omega 320 chronograph I was lucky enough to purchase last year
It dates to 1960 as far as the movement number is concerned then cased in 1962 and according to the papers sold December 1963
In Italy
The box is marked of Italian manufacture but may give you some idea of the style of box these pieces were originally sold in
My example also has a replacement crown but I think like the one on your watch looks just fine
I have the original crown from mine but it it is badly worn
From what I have read you will be lucky to find a good example
Really beautiful possession enjoy

Best Regards

 

Hi
Here’s a photo of another full set 320 shows possibly what the buckle may have been like originally

 

This is fantastic, thanks.
Now at least I know what to look for!
Very nice set you have.

 

Interesting strap.
Reminds me of what I have on mine.
Would love to see that buckle from better angle.

 

Hi
Sorry I only have that one image nice 320 by the way

 

Well, this is what came with mine but I’ve no idea if it was original to the watch.

 

You’ve got to show us a better pic of your dial!
