How do you find out about a 1890s civic watch co pocket watch?

It is rumoured that The Civic Watch Company was a sub-brand of the Omega Watch Company in the early part of the last century, and used on its export watches. (I have seen this in print several times, though have not substantiated it myself. I do, however, have two mens wristwatches in my collection that show obvious similarities: one a 1917 Omega, and the other a Civic of simlar vintage, and so it wold not surprise me if this story were correct.) A question: Are you very sure of your pocket watch's age? If I were very determined to find out more about this watch, I would start at Omega.
