This is not a wrist watch, but it qualifies as an early Omega. I believe it to be from prior to 1910. Louis Brandt was the founder of the company that became Omega, early in the 20th century, when Brandt’s sons re-named the company. Omega was in business when this Louis Brandt & freres, 19-jewel, grade CCR model for railroad use was made. I have two of these, but this is the nicer of the two. Early in the 20th century, Brandt, Omega, Zenith, and Longines produced watches that were approved for use on Canadian railways.
