A genuine Omega Planet Ocean Ultra Deep 6000m is a Grade 5 titanium dive watch rated to 6,000 m, and counterfeit versions fail on four checks: case weight, the solid titanium caseback, the Manta-shaped lugs, and the Calibre 8912 Master Chronometer movement. Verify those first, then inspect the bezel insert, crystal, dial printing, and METAS certification card. A fake that passes all four is rare.
What is the fastest way to spot a counterfeit Ultra Deep?
Weigh the watch in your hand. Grade 5 titanium makes the 45.5 mm Ultra Deep light for its size, while most fakes are cut from 316L steel or a zinc alloy and feel dense or hollow by comparison. Plated steel fakes also flake at the lug edges and show a yellow or copper tone where the plating wears.
Why do the case and lugs give fakes away?
The Ultra Deep uses Omega's Manta lugs, which are asymmetric and twist away from the case instead of the straight lugs of a standard Planet Ocean. Most fakes copy a standard Planet Ocean case and add a depth rating to the dial, so the lug profile stays wrong. Check the crown guards and the helium escape valve at 10 o'clock as well, because both should sit flush with tight tolerances.

What should the caseback look like on a genuine watch?
The real Ultra Deep has a solid, sand-blasted Grade 5 titanium caseback engraved with the model name, the 6,000 m / 20,000 ft rating, and the reference and serial numbers. Any Ultra Deep with a sapphire display back is fake, because this model was never built with an exhibition caseback. Genuine engraving is deep and crisp, while fakes show shallow laser etching, uneven letter spacing, or a glued plate.
How can you check the movement without opening the watch?
The Ultra Deep runs the Omega Calibre 8912, a METAS-certified Master Chronometer with a co-axial escapement, silicon balance spring, and 60-hour power reserve at 25,200 vph. A timegrapher reads the beat rate through the closed case, so 25,200 is the number to expect. The 28,800 vph reading of a Miyota or Asian clone is a clear counterfeit signal, and the seller should allow the test before payment.
Which paperwork proves the watch is authentic?
Each Ultra Deep ships with a Master Chronometer certification card showing the serial number and METAS test results, plus pictogram and warranty cards. The card serial must match the caseback engraving. Ask for a single photo showing the card beside the caseback, because fake kits ship with generic cards that never match the watch.
Do the crystal and dial reveal a fake?
Genuine crystals are thick domed sapphire with anti-reflective coating on both faces, so they show a faint blue or purple tint at an angle and almost no reflection head-on. Fakes use flat sapphire or mineral glass that reflects like a mirror and scratches within weeks. On the dial, applied indices should sit flat, lume plots should be even, and printing under a loupe should show sharp edges rather than dot-matrix steps.
Are high-end super clones of the Ultra Deep convincing?
Not yet. The titanium case, Manta lugs, domed sapphire, and 6,000 m construction are costly to replicate, so most Ultra Deep fakes are mid-tier builds sold as Planet Ocean 6000m. The bezel insert is the weak point: genuine ceramic inserts have numerals that sit flush in the ceramic, while fake inserts look glossy, raised, or printed.
What red flags should end the deal?
- Price far below the five-figure retail range for a full set.
- A display caseback on a 6,000 m dive watch.
- Shallow or misaligned caseback engraving.
- Bezel that feels gritty or does not line up at 12 o'clock.
- Serial number that does not match the certification card.
- Weak or patchy lume after 30 seconds under a lamp.
When two or more of these signs appear together, walk away. A genuine Ultra Deep is a sealed titanium instrument built for saturation diving, and that standard shows in the weight, the engraving, and the paperwork long before you ever turn a bezel.
