The fake Omega Planet Ocean Ultra Deep is a counterfeit copy of Omega's 6,000 m dive watch, and it fails on three points almost every time: case thickness and weight, the depth-rating text on the dial, and the METAS-certified Master Chronometer Calibre 8912 inside. The genuine watch measures 45.5 mm across and about 18.1 mm thick in Grade 5 titanium or O-MEGASTEEL, and no replica on the market reaches its 6,000 m (20,000 ft) rating. Most copies hold roughly 30 to 100 m of real water resistance, so treat any "Ultra Deep" replica as a desk watch only.
What are the real specs of the Omega Planet Ocean Ultra Deep?
The Ultra Deep entered regular production in 2022, three years after an Omega Seamaster prototype reached the bottom of the Mariana Trench. It is the deepest-rated watch in the catalog.
- Case: 45.5 mm wide, about 18.1 mm thick, in Grade 5 titanium or Omega's O-MEGASTEEL
- Movement: Co-Axial Master Chronometer Calibre 8912, 60-hour power reserve, 15,000 gauss magnetic resistance
- Certification: METAS Master Chronometer status plus ISO 6425 diver compliance
- Crystal: domed sapphire with anti-reflective coating on both sides and a laser-engraved Omega symbol
- Bezel: ceramic insert with a Liquidmetal dive scale and a Super-LumiNova pip
- Caseback: titanium Manta-style back engraved with 6,000 m / 20,000 ft text
How can you tell a fake Omega Planet Ocean Ultra Deep?
- Weigh it in the hand. The titanium reference feels light for a 45 mm watch, while most replicas use steel cases and feel noticeably heavier.
- Read the dial print. Genuine dials show "6000m / 20000ft" in crisp, evenly spaced type; fakes use thinner fonts, wrong spacing, or a plain "600m" line.
- Study the caseback. The genuine 8912 shows Geneva stripes, blackened screws, and deep engraving; replicas mount a decorated generic automatic with shallow etching.
- Angle the crystal. The etched Omega logo appears only at certain light angles. Many fakes skip it or use a printed sticker.
- Turn the bezel. Real Liquidmetal inserts sit flush with sharp lume and firm clicks. Replica inserts are printed and often misaligned.
- Check the paperwork. A genuine watch ships with a METAS Master Chronometer card, pictogram card, and serial numbers that match the case.
What do Ultra Deep replicas get wrong most often?
Case profile is the biggest giveaway, since fakes are usually built on a standard Planet Ocean case with added thickness. The Manta caseback engraving comes out blurred, and the dial gradient and depth-rating text rarely match the original printing. Bracelet clasps also skip the micro-adjust system, and the sapphire dome is flatter than the real crystal.
Is a fake Ultra Deep safe to dive with?
No. Counterfeits are not tested to ISO 6425 and their gaskets carry no certification, so water can pass the seals at depth and destroy the movement. Relying on a replica as a dive instrument is a genuine safety risk, not just a cosmetic one.
How much does a fake Omega Planet Ocean Ultra Deep cost?
Replica Ultra Deep watches sell for roughly $150 to $700 depending on the factory tier and whether the seller ships a titanium-style or steel case. Genuine references retail near $12,000 to $13,000, so a low price on a "new" watch is the first warning sign.
Are counterfeit Omega watches legal to buy?
Counterfeits infringe Omega's trademarks, and importing or reselling them is illegal in the United States and most of the European Union. Buyers who want the Ultra Deep look without legal exposure should consider homage watches or a pre-owned genuine Seamaster instead.
