🔎 Case Notes

The Omega Seamaster Professional Ref. 210.30.42.20.03.001 is one of the defining modern dive watches of the last decade — a piece that combines Omega’s unmistakable Seamaster identity with contemporary materials and strong everyday wearability.

This reference features the signature blue ceramic dial with laser-engraved wave pattern, paired with a matching blue ceramic bezel. The result is a dial that shifts beautifully in changing light while retaining the bold, high-contrast look that has made this reference such a collector favorite.

At 42mm, the case offers a balanced wrist presence that feels substantial without becoming oversized. The familiar helium escape valve, skeleton hands, and scalloped bezel all reinforce the Seamaster’s instantly recognizable design language.

This example dates to 2020 and is presented in excellent pre-owned condition, showing minimal signs of careful wear. The dial and sapphire crystal remain clean, and the bracelet presents very well.

The watch includes box, papers, and cards, and is currently sized to fit approximately a 7.25–7.5 inch wrist.
