The Planet Ocean is Omega's serious dive watch — 600m water resistance and a bolder presence than the Diver 300M. Identifying your generation is the key to an accurate valuation.

The short answer
The Omega Seamaster Planet Ocean is a 600m dive watch that has run through several generations since 2005 — early (aluminium bezel), ceramic, and Master Chronometer — with sizes and movements that changed between them. There are also GMT and chronograph variants. Because specification differs by generation, Fair Vintage values your specific example rather than "a Planet Ocean" in the abstract: we confirm the generation and movement, grade the condition, value the box and papers, and give a free, no-obligation valuation — all by post from Bedfordshire, with insured postage and payment by bank transfer within 72 hours of you accepting.
Rather than a single set of sizes, the Planet Ocean has evolved. Across all of them the defining figure is 600m water resistance. There are also GMT and chronograph variants, and Bond/limited editions where genuinely relevant — worth flagging only when it's actually the watch you own.
Commonly 42mm and 45.5mm, with an earlier calibre generation and an aluminium bezel.
Ceramic bezels were introduced, Liquidmetal was used in bezel numerals on some models, and the movement families were updated; additional sizes appeared.
Configurations including 39.5mm, 43.5mm and 45.5mm, with Master Chronometer movement families.
The range also includes GMT and chronograph versions; each is valued on its specific reference and generation, not as a generic Planet Ocean.
Generation and movement family, case and bezel condition, whether the watch has been polished, bracelet or strap condition, and completeness of the set. Because specification differs by generation, we value your specific example rather than "a Planet Ocean" in the abstract.
Get the generation right before you sell. Planet Ocean values depend on getting the generation and movement right. A specialist prices your example on its actual specification rather than a one-size-fits-all figure.
Buyers like the Omega card or e-warranty details, the box, spare strap or bracelet links, and any tools or extra strap supplied with certain references. Service history is useful on the earlier generations.
We buy Planet Oceans without box and papers, identifying the reference and generation from the watch and reflecting any missing items clearly.
Send the reference and photos for a free, no-obligation valuation. If you accept, we provide a free, fully insured Royal Mail Special Delivery label, check the watch, and pay by bank transfer within 72 hours. The service is entirely postal, run from Bedfordshire.

What water resistance does the Planet Ocean have?
600m across the range — that's a defining feature of the model.
Do you buy the GMT and chronograph versions?
Yes — both are valued on their specific reference and generation.
How do I tell which generation I have?
The bezel material, movement and reference help; send photos and the reference and we'll confirm it.
Is a Bond or limited edition worth more?
It can be, but only when it's genuinely that edition; we assess it on its own terms.
