Which one I'd pick
Discontinued ref vs current model: the current Planet Ocean is $8,600 to $9,200 at Omega. The outgoing .01.001 at $6,800 new is the better value if you don't need the latest version.
Planet Ocean vs Diver 300M: the Planet Ocean is bigger, thicker and rated to 600 m. The 300M is the more everyday-sized diver.
What to check before you buy
- Box and papers: a brand warranty card matters for resale. Grey-market new watches may carry the dealer's warranty instead of the brand's, so ask which one you're getting.
- Size: at 43.5 mm with a helium valve this is a big watch. Try one on before you buy.
- Fakes and red flags: avoid prices far below the grey-market numbers above, stock photos only, or sellers who won't show the caseback, clasp and warranty card.

History
The Seamaster line dates to 1948. The Planet Ocean joined it in 2005 as Omega's more heavy-duty professional dive watch, borrowing from Omega's dive-watch past.
In 2019, three experimental Seamaster Planet Ocean Ultra Deep Professional watches survived a 10,928 m dive to the bottom of the Mariana Trench, attached to a submersible.
The 215.30.44.21.01.001 is the 43.5 mm steel model with the Co-Axial Master Chronometer Calibre 8900 and a 60-hour power reserve. Omega has since replaced it with newer Planet Ocean models.
