The watch is special enough that I will copy a couple of the photos over:



I don’t know much about this watch other than it has a very high grade chronometer movement.

Not to worry, you’re doing great 👍

We also have a long-running pocket watch thread at https://omegaforums.net/threads/calling-all-pocket-watch-buffs.127856/. I assume you have a nice collection and perhaps might share some with us? 😀

If I'm not mistaken it's already been kind of discussed here:

The subject Omega is marked as “adjusted to 6 positions”. The dial is marked “Chronometre (sic)”. It has a bi-metallic, temperature compensating balance wheel, Breguet hairspring, cam-type micrometer regulator. It has most of what would be considered as railroad standard, but I doubt the fancy “Omega” hands would have been acceptable. And it is not lever set. I checked the time service rules for many American railroads. Omega is not listed as having been approved for railroad use on U S railroads, according to the tables I read. However, it is possible that a railroad, somewhere, might have accepted that one. The case on the Omega is .375 (9-karat gold), and is by Dennison, an English company. So it would appear as though the subject Omega was meant for the domestic market in Britain where it might have been railroad approved.

According to the time service rules for the CPR in Canada as in effect from 1899 to 1910, Brandt-Omega grade CCR (16-size, 19-jewels), CCCR (16-size, 23-jewels), DDR (18-size, 19-jewels), and DDDR (18-size, 23-jewels) were accepted. The subject is not any one of those. I’ve shown a Brandt, 16-size, 19-jewel, grade CCR, just for comparison. It was railroad approved in Canada.

Among the notable differences between the subject Omega and the Brandt (aside from the difference in jewel count) is the fact that the Brandt has a jewelled safety barrel, and it is lever set. The Omega has a 5xxxxxxx, so it is circa 1916, and the Brandt has a 2xxxxxx serial number which is circa 1905.

Maybe this will help you decide whether to buy it, or walk.

Except, the watch in the link is in a hunter case, and the hands are different.

You’re right. I was looking at one of the other watches.

The picture showing the inside case back where the hallmark and date letter are shown is terrible. If that is an upper case C, it could be 1927 or 1928. But if it is a lower case c, then it could be 1902 or 1903. Another consideration might be, is that case original to the movement?

The serial #/date references generally available are only estimates. The one I just checked lists a 5 million serial number as being 1916, and a 6 million serial number as being 1923. So who is to know wherein lie the facts of the matter? The subject Omega appears to have been made somewhere between 1916 and 1923! That still doesn’t explain the case which appears to be later than 1923. Take out of it all what you will.

The Birmingham hallmark is for 1927/1928. It ties in with the date range shown in AJTT. The movement may be older but that's not unusual with special or high grade movements.
