A fake Omega Planet Ocean Ultra Deep 6000m copies a 45.5 mm titanium dive watch that Omega rates to 6000 m (20,000 ft). No replica holds that rating. Most sellers list 3 to 5 ATM for these watches. Some list no number at all. Buy one for the shape and the dial, not for diving.
Genuine specs the copy follows
- Case: grade 5 titanium, 45.5 mm wide, 18.12 mm thick
- Water resistance: 6000 m, built to ISO 6425:2018
- Crystal: domed sapphire, both sides
- Bezel: ceramic insert, dive scale, lume pip at 12
- Movement: Omega Co-Axial Master Chronometer 8912, 60 h power reserve
- Magnetism: rated to 15,000 gauss
The line traces to a 2019 prototype that rode a submersible to about 10,900 m in the Mariana Trench. Omega put the production version on sale in 2022.
What replicas get right
Case outline, dial text, date window at 3 o'clock, hand shapes, and bezel markings come close on the better copies. Photos at arm's length pass. Lume color matches on mid and high tiers. Cheap units stamp the case back text instead of engraving it.
What replicas miss
Thickness is the common error. Many copies run 1 mm to 3 mm thicker than 18.12 mm. Case weight is the second error. Titanium has a density near 4.5 g per cubic centimeter. 316L steel sits near 7.9 g per cubic centimeter. A steel copy of a titanium watch feels heavier on the wrist.
Movements split into three groups. Low tiers use quartz. Mid tiers use modified third-party automatics. High tiers use clone movements. None carry METAS certification. That test runs on the finished watch, not on the movement alone.
Crystal is another tell. Cheap units use flat sapphire or mineral glass. The genuine crystal domes over the bezel. Crown threads turn fewer times on copies, and the metal is softer.
Water resistance on copies
Replica gaskets are not pressure tested at the factory. A 5 ATM label on a listing means splash resistance at best. Do not swim with a copy. Do not open the case back. Once opened, the seal is compromised.
Price bands
- Under $100: quartz, mineral glass, steel case, printed dial
- $150 to $300: automatic, sapphire, better bezel action
- $300 to $500: titanium claims, closer thickness, clone movement
Genuine Ultra Deep models list above $10,000 USD in the US.

Legal note
In the US, 18 U.S.C. § 2320 covers trafficking in counterfeit goods. Sellers that label a watch as a replica or a first copy differ from sellers who pass it off as genuine.
