Quick answer

A fake Omega Planet Ocean Ultra Deep 6000M copies the look of a 45.5 mm, 6,000 m dive watch. It does not copy the engineering. Fakes do not carry Omega Calibre 8912, are not METAS certified, and are not pressure tested to 6,000 m (20,000 ft). Most run a generic automatic movement inside a case that measures 1 to 2 mm off the genuine diameter.

What the real Ultra Deep 6000M is

Omega launched the Ultra Deep 6000M in 2022. It traces back to the Ultra Deep Professional, a prototype fixed to the DSV Limiting Factor during the 2019 Five Deeps Expedition. That dive reached 10,928 m in the Mariana Trench.

  • Case: 45.5 mm diameter, about 15.6 mm thick.
  • Depth rating: 6,000 m / 20,000 ft, ISO 6425 divers' watch testing.
  • Movement: Co-Axial Master Chronometer Calibre 8912, 60-hour power reserve, 25,200 vph.
  • Magnetic resistance: 15,000 gauss.
  • Case materials: O-MEGASTEEL and Grade 5 titanium, depending on reference.
  • Retail: five figures in USD, about $11,000 and up. Reference and strap change the number.

Where fakes differ

Case and crystal

Measure the case with calipers. Replica cases land near 44 mm or 46 mm, and the caseback profile is shallower. The genuine crystal is domed and thick because it must hold at depth. Replica crystal thickness is lower. Case weight is lower too, since the alloy is not O-MEGASTEEL or Grade 5 titanium.

Movement

Calibre 8912 beats at 25,200 vph, hacks, and winds in both directions. Replica movements are often Chinese automatics at 21,600 vph. Signs: a date that creeps past midnight instead of snapping, a rotor that rattles, and a sweep that stutters. The genuine watch ships with a METAS Master Chronometer card printed with a test number. Fakes ship with a blank card or none.

Dial, bezel, and lume

Check the printed text under a loupe. Replica dial ink spreads at the edges, and the font weight is wrong on the depth line. Rotate the bezel. A fake insert sits off-center at 12 o'clock and has backplay. Charge the lume. Genuine Super-LumiNova fades over hours. Cheap paint dies in minutes.

Depth rating

A dial that reads 6000m on a fake means nothing. Gaskets, crystal thickness, and caseback threads are different. Assume a replica holds 30 m to 100 m. Do not dive with one.

Price and paperwork signals

Genuine Ultra Deep 6000M watches sell above $10,000 USD. A listing at $300 to $900 is not a discount. Serial numbers on fake warranty cards often repeat across listings. Sellers using words like mirror, 1:1, or clone are describing a replica.

Bottom line

The Ultra Deep 6000M is a tool built around a 6,000 m case and a METAS tested movement. A fake is a cosmetic shell. Judge it as a costume piece, not a dive instrument.
