The Omega “Medicus” CK650 is a genuine piece of horological history. Released in the 1930s for doctors and nurses, it was one of Omega’s first models with a central seconds hand, making it practical for medical timing – a true tool watch from the Art Deco era. This example features a stepped case, a sector dial with rich patina, and original blue steel hands, all of which have survived remarkably well for nearly a century. A rare, highly collectible reference that combines historical significance and functional design.  **Condition:** Very good vintage condition. Dial shows full, even patina. The original blued hands are intact. The case retains crisp edges and movement runs smoothly, although the service history is unknown. Aftermarket strap. Please see the pictures for full condition and clarity.  **Reference:** CK650 **Case Size:** 30.6 x 36mm stainless steel case with a thickness of 10.3mm and a lug width of 16mm. **Crystal:** Acrylic **Movement:** Omega 23.4SC, manual wind with 15 jewels, 43-hour power reserve, and 18,000 bph.
