The replica Omega Planet Ocean Ultra Deep 6000m is a copy of a 45.5 mm professional dive watch rated to 6,000 meters. Most versions use stainless steel, a domed sapphire crystal, a ceramic dive bezel and an automatic clone movement. No replica carries real depth certification, so its water resistance is cosmetic rather than functional.
What is the genuine Ultra Deep 6000m?
Omega released the Seamaster Planet Ocean Ultra Deep in 2022 as the production version of a prototype that descended to the deepest point of the Mariana Trench. The factory rating is 6,000 m / 20,000 ft, tested to the ISO 6425 dive watch standard. Reference materials include O-MEGASTEEL and Grade 5 titanium.
- Case size: 45.5 mm diameter, roughly 15.2 mm thick
- Water resistance: 6,000 m / 20,000 ft, ISO 6425
- Crystal: domed sapphire, bonded directly to the case
- Movement: Co-Axial Master Chronometer Calibre 8912, METAS certified
- Magnetic resistance: 15,000 gauss
- Lugs: fixed manta-shaped lugs on the original
Why the manta lugs matter on a copy
The original uses fixed manta lugs with a pin-and-screw strap system, so a normal spring bar bracelet will not fit. Replica factories either mimic the manta shape or substitute standard lugs for practicality. Check close-up photos of the lug ends before buying if you plan to swap straps.
How close is the replica to the real watch?
Dial, hands and bezel
Better copies reproduce the gradient dial, the broad arrow hands and the printed depth rating fairly well. The usual weak points are bezel action and lume, which tend to be dimmer and less even than the original.
Case and finishing
O-MEGASTEEL is an Omega-specific alloy, so replicas use 316L or 904L stainless steel instead. Brushed and polished transitions look soft on lower tiers and noticeably sharper on top tiers. Titanium versions are rarely genuine titanium, which changes the weight on wrist.
Movement inside the copy
Most versions run a Chinese automatic such as a 2824 clone, and some decorated builds add an 8912-style rotor and engravings. None are METAS Master Chronometer certified, so daily rate is looser and more variable. A known Seiko NH35 is often the safer long-term choice.
Can a replica survive 6,000 meters?
No. Depth ratings depend on caseback thickness, gasket design and crystal bonding that factories do not pressure test. Many copies leak at the crown or caseback during a shower, and saltwater is worse. Keep any replica out of diving, snorkeling and hot water.
What to check before you buy
- Case size: look for a true 45.5 mm diameter and thickness under about 16 mm.
- Crystal: domed sapphire with inner anti-reflective coating, not mineral glass.
- Bezel insert: ceramic with a crisp, fully filled dive scale and a lume pip.
- Caseback: correct Seamaster or Manta engraving and reference text.
- Lugs and bracelet: confirm lug width and whether links use screws or pins.
- Lume: charged markers, hands and bezel pip rather than printed paint.
Wearability and sizing
A 45.5 mm case with a tall profile wears large and suits wrists around 7 inches and up. The domed crystal adds visual bulk even though the case length tracks close to the original. If the genuine watch feels too big for you, the replica will feel the same.
Frequently asked questions
Is the replica a real Omega?
No. It is a third-party copy with no connection to Omega or the Swatch Group, and it carries no factory warranty.
Does the replica have a helium escape valve?
No. The original Ultra Deep eliminates the helium valve because the crystal is bonded straight to the case, and copies simply omit the feature.
Why does the engraved depth rating not match real performance?
Depth figures are printed for appearance and are not verified in a pressure chamber. Only an ISO 6425 certification proves a 6,000 m rating.
