The current standard generation is the fourth, announced by OMEGA in 2025; before comparing or buying a model, verify its full reference and the specifications listed for that watch.
For a practical starting point, distinguish the 600M models from the specialist 6000M Ultra Deep, then compare case size, functions, and strap or bracelet configuration. The cited references below illustrate why the collection name alone is not enough to establish what a particular watch offers.
What is the current Planet Ocean generation?
OMEGA announced the fourth Planet Ocean generation on 18 November 2025, 20 years after the first Planet Ocean was released. OMEGA described the launch as a complete redesign, with changes to the case and bracelet architecture and seven new watches across three watch heads and multiple attachment options. The 20-year chronology is OMEGA’s own framing in its launch announcement.
In a 1 May 2026 announcement, OMEGA said the fourth generation was available worldwide in seven versions, in blue, black, or signature orange, with rubber-strap or stainless-steel-bracelet options. That announcement describes the range of configurations, not local stock or availability at a particular seller.

Planet Ocean 600M and 6000M: key differences
The standard 600M references and the 6000M Ultra Deep are distinct watches with different stated depth ratings and specifications. The table compares three references documented in OMEGA manuals; these details should not be generalized to other Planet Ocean models.
| Reference | Case | Water resistance | Movement and functions | Attachment |
|---|---|---|---|---|
| Planet Ocean 600M, 217.32.42.21.01.001 | 42 mm; titanium and steel | 600 m / 2,000 ft | Calibre 8912; 60-hour reserve; time-zone function; rotating diving bezel | Rubber strap |
| Planet Ocean Worldtimer, 215.92.46.22.01.007 | 45.5 mm ceramic | 600 m / 2,000 ft | Calibre 8938; 60-hour reserve; date, time-zone and world-time functions; rotating diving bezel; helium escape valve | Rubber strap |
| Planet Ocean 6000M Ultra Deep, 215.92.46.21.01.001 | 45.5 mm titanium | 6,000 m / 20,000 ft | Calibre 8912; 60-hour reserve | Check the exact reference documentation |
Specifications in this table come from OMEGA user manuals for the listed references; the publication date of those manuals was not established in the research. A stated water-resistance rating is a product specification, not a guarantee about the present condition of an individual watch.

Which Planet Ocean size should I choose?
Start with the case dimensions of the exact reference, then consider its material, functions, and attachment. The documented examples here range from a 42 mm 600M model to 45.5 mm Worldtimer and Ultra Deep models. Those figures describe the cited references only; they do not establish the dimensions of every Planet Ocean or predict how a watch will fit your wrist.
- Check the full reference. Use it to confirm the model and find its own specifications.
- Compare the case and material. The cited 42 mm reference uses titanium and steel; the cited 45.5 mm Worldtimer uses ceramic, while the cited Ultra Deep uses titanium.
- Choose functions for your needs. The cited standard 600M reference has a time-zone function; the Worldtimer adds world-time functionality. Do not assume other references share those functions.
- Check the attachment. Confirm whether the particular watch comes with a rubber strap or bracelet and verify compatibility before buying replacement parts.
- Try the exact watch if possible. The documented dimensions do not establish comfort or fit for an individual wearer.
What is the difference between the Planet Ocean Worldtimer and standard models?
The cited Planet Ocean Worldtimer reference, 215.92.46.22.01.007, has a 45.5 mm ceramic case and adds date, time-zone, and world-time functions. OMEGA’s manual lists a 600 m / 2,000 ft rating, Calibre 8938 with a 60-hour reserve, a rotating diving bezel, and a helium escape valve for this reference.

By comparison, the cited 42 mm Planet Ocean 600M reference, 217.32.42.21.01.001, uses Calibre 8912 and has a time-zone function. Compare the exact references and their manuals rather than treating either description as a specification for every Worldtimer or standard Planet Ocean.
How does the Ultra Deep differ from the Planet Ocean 600M?
The Ultra Deep is a separate specialist variant, not simply another name for a standard 600M Planet Ocean. OMEGA’s manual for reference 215.92.46.21.01.001 lists a 45.5 mm titanium case, a 6,000 m / 20,000 ft rating, Calibre 8912, and a 60-hour reserve. The rating is specific to that reference and should not be applied to 600M models.

Buying checklist
- Record the complete reference number and confirm it against the watch and its documentation.
- Verify the case size, material, water-resistance rating, movement, and functions for that exact reference.
- Confirm the included bracelet or strap and any components described in the listing.
- For a pre-owned watch, ask about service history, documentation, seller terms, and the watch’s current condition.
- Do not rely on a printed water-resistance rating alone to establish the condition or water safety of a pre-owned watch.
OMEGA’s May 2026 announcement describes the fourth generation as available worldwide, but the research did not establish local stock, prices, specific marketplace listings, or affiliate eligibility. Check with a seller for current regional availability and verify that the offered watch matches the reference and configuration you intend to buy.

What is the difference between Planet Ocean 600M and 6000M?
They have different reference-specific ratings. OMEGA’s manual lists 600 m / 2,000 ft for the cited 600M reference and 6,000 m / 20,000 ft for the cited Ultra Deep reference. Confirm the rating for the exact watch rather than applying either figure to the whole family.
Which Planet Ocean size should I choose?
Choose based on the dimensions of the exact reference and how it fits when tried on. The cited examples include a 42 mm 600M model and 45.5 mm Worldtimer and Ultra Deep models, but those examples do not cover every Planet Ocean.
What is the difference between the Planet Ocean Worldtimer and standard models?
The cited 45.5 mm Worldtimer reference adds world-time functionality, alongside date and time-zone functions. The cited 42 mm 600M reference has a time-zone function; check each reference’s manual for its specific functions.
Does a 600M rating mean a pre-owned watch is safe to dive with?
No. The rating is a manufacturer specification for a reference; it does not establish the present condition of an individual watch. Have a pre-owned watch assessed by a qualified service provider before relying on it in water.
