Hello
@vflygare and welcome to the forum!
Vintage Omega
cognoscente will insist that the model name "Medicus" only refers to a specific square-case model with a center second 23.4SC caliber. The watch, with its large sweep second hand, was marketed to doctors as a useful tool for measuring heart rates. However, we've all become sloppy over time, and most folks (including Omega) now use the name Medicus to refer to all of the early 23.4SC wristwatches. I am hoping our early Omega expert
@Tire-comedon will arrive to advise as to your exact model.
