Seamaster Diver 300M 210.30.42.20.03.001 (Blue)
The Seamaster Diver 300M with the blue wave-pattern dial and laser-engraved ceramic bezel is Omega's modern dive icon and, as James Bond's on-screen watch, one of the most accessible blue-chip divers to enter.
Read the product overview
The figure shown is the boutique list price, not a resale quote. With healthy supply, this reference typically trades close to retail, so condition and complete provenance — rather than scarcity — drive what an individual piece fetches. A full set with box and card and an unworn example of the Master Chronometer Calibre 8800 earns the firmest pricing on authenticated platforms.

How we assess prices
We use in-stock offers checked within 72 hours. Scores compare the current offer with that retailer’s observations from the last 90 days, requiring at least 14 observed days and a price from about 30 days ago. Suspect records withhold the score. Retailer conditions and prices can change.
