🔎 Case Notes
The Omega Seamaster Professional 300M Ref. 212.30.41.20.03.001 represents one of the most beloved executions of the Seamaster line — combining professional dive capability with a rich blue colorway that has become synonymous with the model.
This reference features the iconic blue dial paired with a matching blue unidirectional dive bezel. The sculpted case, skeletonized hands, and helium escape valve at 10 o’clock anchor the watch firmly in Omega’s professional dive-watch heritage, while the proportions make it comfortable for everyday wear.
At 41mm, the watch offers balanced presence without bulk. This example is presented in very good pre-owned condition, showing light, honest signs of careful wear. The case lines remain strong, the dial and crystal are clean, and the bezel retains crisp definition. It includes its original box, papers, and warranty card, with the booklet missing, and the bracelet is currently sized to fit approximately a 7¼–7½ inch wrist.
