I remembered I had an old advertising piece from 1952 on a vintage Omega chronometer. The thing is. The watch doesn’t seem to exist.

A search on the model only brings up the advertisement. No pictures on an actual watch.

in the history of Longines. There is an also an ad showing a gold cased chronometer that never existed. I emailed Longines to inquire about the model and was told it never made. So why creat an ad for a non existent watch?

The Omega C 180SC. Curious if ever made

Any info Mac?

It's an attractively produced ad. Makes me want the watch, even with the white strap.

Hello Don,

I have never heard of this reference nor did I find any info on the microfiche when I researched in the Omega archive.
Do you happen to have a larger version of this AD ? the photo is not large enough and its a bit blurry, so I can´t read the text.

Note the Advert is English. This may suggest that the watch in question was UK national production, ie built up using a Dennison (or similar) case, hence the strange model number. Omega may not even have a record of this since they supplied only movement, dial and hands and it could be a local prototype that never made it. Were there an extant Dennision archive, and if there is I'm not aware of it, that would be the place to look maybe.

The ad does say English hall marked case. The caliber 283 was produced with a swan neck regulator, but nothing saying it was a chronometer movement and production was extremely limited

Image posted by Sharp shows a standard 283. No added features. Plain crown and ratchet wheels, so no added polishing as the RG models
