🔎 Case Notes

The Omega Seamaster Professional 300M Ref. 212.30.41.20.01.003 is a modern classic — a reference that represents the Seamaster line at one of its most refined and universally loved points.

At 41mm, the watch strikes a near-perfect balance between presence and practicality. This example is offered in excellent pre-owned condition, showing only minimal signs of careful wear. The case lines remain crisp, the dial and crystal are clean, and the bezel presents beautifully. It includes its full kit and is currently sized to fit approximately a 7¼–7½ inch wrist.
