The Omega Seamaster Planet Ocean Ultra Deep 6000M is a 45.5 mm dive watch rated to 6,000 m (20,000 ft), and it is one of the hardest Omega models to copy convincingly. Fake versions appear regularly online, but they almost always miss on case thickness, dial gradient, crown threading and movement. No replica of this watch can survive the pressure its dial claims.

  • Magnetic resistance: 15,000 gauss, METAS certified
  • Crystal and bezel: domed sapphire with anti-reflective coating on both sides, ceramic unidirectional bezel

How do you spot a fake Ultra Deep 6000M?

Start with the case. Genuine titanium feels light for its size, while many fakes use steel and get the thickness wrong in one direction or the other. A case that is too thin for a 6,000 m rating is the single clearest warning sign.

  • Dial gradient: the real blue fade is smooth and even. Fakes often show banding or a purple tint under daylight.
  • Bezel action: 120 crisp clicks, no backplay, and the triangle lines up exactly at 12. Fake inserts sit slightly rotated.
  • Crown and helium valve: threads should feel smooth and the crown should screw down flush to the case.
  • Caseback: engraving is deep and sharp, with the seahorse medallion and matching reference and serial numbers.
  • Movement: the 8912 beats at 3.5 Hz with a silicon balance spring. Most fakes use a generic 21,600 vph automatic.
  • Lume: genuine Super-LumiNova glows evenly for hours. Fake lume is dim and fades within minutes.

Can a replica really be rated to 6,000 m?

No. That depth equals roughly 8,700 psi, which is why the genuine watch uses a domed caseback shaped like a diving bell and a sapphire crystal that thickens toward the center. Replicas are usually not pressure tested at all, and most leak in a pool or shower. Treat any 6,000 m claim on a fake as decoration, not capability.

How do you verify a genuine watch?

Every Ultra Deep ships with a METAS Master Chronometer card listing the movement's serial and test results. The serial is engraved on the caseback and must match the card and the warranty record. Omega backs the watch with a five-year warranty, so a seller with no paperwork, no card and no service history is a hard pass.

Is the Ultra Deep 6000M too big for daily wear?

At 45.5 mm wide and about 18 mm thick, it wears tall on most wrists and will not slide under a shirt cuff. That bulk is the price of the depth rating, and it is also why fakes often feel oddly proportioned. If you want the look without the height, a standard Planet Ocean is the better reference point.
