The short answer

If you are shopping for an Omega Seamaster Planet Ocean, buy the genuine watch from an authorized dealer or a documented pre-owned seller, and treat the phrase "1000m" as a red flag. Omega does not make a 1000-meter Planet Ocean. The real dive ratings in this family are 600 meters for the standard Planet Ocean, 1200 meters for the Ploprof, and 6000 meters for the Planet Ocean Ultra Deep. Listings that advertise a "Planet Ocean 1000m" are almost always counterfeits, mislabeled gray-market stock, or a seller repeating a spec they copied from another listing. A genuine Planet Ocean arrives with Master Chronometer certification, a warranty card, and a serial number that matches the case, the movement, and the paperwork.

What to look for

The Planet Ocean is one of the most counterfeited dive watches on the market, so verify structure before you verify cosmetics. The details below are the ones counterfeiters most often get wrong.

  • Depth rating actually engraved on the caseback, matching the dial text and the reference number.
  • Helium escape valve at 10 o'clock with a crown that threads down flush and seals cleanly.
  • Co-Axial Master Chronometer movement (calibers 8800, 8900, or 8912 depending on size and date layout).
  • METAS certification card with a test number that ties to the specific watch, not a generic photocopy.
  • Ceramic bezel insert with a dive scale that is crisp at the edges, not printed and sealed under a plastic dome.
  • Sapphire crystal with anti-reflective coating on both faces and no rainbow halo under a lamp.
  • Serial number stamped on the lug, engraved inside the caseback, and printed on the card, all identical.

Spec bands by model

Planet Ocean 600M

The mainstream line. Cases run from roughly 39.5mm to 43.5mm in steel, titanium, or gold, with 600-meter water resistance, a screw-down crown, and a helium escape valve. This is the version most buyers actually want, and the one with the deepest supply of honest pre-owned examples.

Planet Ocean Ultra Deep 6000M

A 45.5mm titanium tool watch built from the dive that set the record for the deepest dive by a commercial-rated watch. It uses a domed sapphire with a conical shape and a special caseback, and it is genuinely heavy on the wrist. Expect a five-figure price and a small number of listings.

Ploprof 1200M

A separate design with a monobloc case, an offset crown, and a bezel release button. Buyers who say "1000m Omega diver" often mean this watch. If the seller is calling it a Planet Ocean, the listing is wrong somewhere.

Pitfalls to avoid

  1. Believing an inflated depth number. Water resistance is tested, printed, and documented. A seller who invents a rating has invented the rest of the listing too.
  2. Skipping the certification check. Master Chronometer status is an eight-test protocol with published tolerances, and the card is part of the watch.
  3. Buying on cosmetics alone. A sharp photo of a cloned dial says nothing about the movement, the seals, or the caseback engraving.
  4. Ignoring bracelet and case condition. A polished or refinished case removes the original bevels and hides the fact that the watch was over-polished.
  5. Diving with an untested watch. Every dive watch, genuine or not, should be pressure tested by a watchmaker before it goes near open water.
  6. Assuming a low price is a bargain. On a Planet Ocean, a price far below the market almost always means a counterfeit, a stolen watch, or a watch with a swapped movement.

FAQ

Does Omega make a 1000m Planet Ocean?

No. The Planet Ocean line is rated to 600 meters, the Ploprof to 1200 meters, and the Ultra Deep to 6000 meters. There is no 1000-meter reference.

Can a counterfeit dive watch handle real depth?

Unlikely. Counterfeit cases are rarely built to a tested standard, gaskets are generic, and crowns often fail to seal. A fake rated "1000m" on a marketplace listing has usually never seen a pressure tank.

How do I confirm Master Chronometer certification?

Check that the card carries a certification number, that it matches the movement, and that the watch is listed in Omega's records. A photocopied card with no matching number is a warning sign.

Is buying or importing a counterfeit watch legal?

Selling and importing counterfeit goods violates trademark law, and shipments can be seized by customs. Counterfeit watches also carry no warranty, no parts support, and no resale value, which is why the long-term cost is higher than the purchase price suggests.
