The fake Omega Planet Ocean Ultra Deep is a replica of the 45.5 mm Seamaster Planet Ocean Ultra Deep released by Omega in 2022. Genuine versions carry a 6,000 m water resistance rating, a METAS Master Chronometer certification, and a Co-Axial Calibre 8912. Replicas carry none of those three. Replica listings show case widths from 44 mm to 46 mm, depth claims from 30 m to 100 m, and no published pressure test data.
Genuine Baseline
Omega built the Ultra Deep after the 2019 Five Deeps Expedition. A prototype reached 10,928 m in the Mariana Trench on Victor Vescovo's submersible. The retail model followed in 2022. Titanium Grade 5 case, 45.5 mm wide, about 18 mm thick. Sapphire crystal domed on both faces. Manta lugs use a pin system instead of spring bars. Movement is the Co-Axial Master Chronometer Calibre 8912: 60 hours of reserve, 25,200 vph, rated to 15,000 gauss. Steel versions use O-MEGASTEEL. Retail sits near five figures USD.
What Replica Builders Copy
- Case outline and the 45.5 mm width on top-tier builds.
- Domed sapphire crystal with inner anti-reflective coating on some units.
- Ceramic bezel insert with a printed dive scale.
- Dial text, broad arrow hands, and the 6 o'clock date window.
- Screw-down crown and a helium escape valve at 10 o'clock.
Where Replicas Fail
Thickness is the first tell. Many replicas measure 16 mm to 17 mm against the genuine 18 mm. Weight is the second. Titanium replicas often land within 10 g of the steel ones because the case is 316L stainless with a coating. The helium escape valve on most replicas is decorative and does not vent. Bezel action differs: genuine bezels run 120 clicks with no back play. Caseback engraving depth and font weight differ from the factory stamp. Movement decoration is printed, not plated, on lower tiers.
Water Resistance Reality
ISO 6425 sets the test standard for divers' watches, including pressure and thermal shock checks. No replica factory holds that certification. A 100 m claim on a listing means nothing without a pressure report. Gaskets on budget units are thin. Crown threads are cut to a coarser pitch than the genuine part. Pool water is the practical limit for most units, and some leak sooner.
Price Bands
Ultra Deep replicas sell in three bands: about $100 to $180, $200 to $350, and $400 to $600. Top-band units use a clone 8912 or a decorated 2824 base, sapphire crystal, and a titanium-look case. Bottom-band units use mineral glass and a 21,600 vph movement. Specs change by batch, so two units from the same seller can differ.
Checks Before Payment
- Ask for a caliper photo of case thickness.
- Ask for a scale photo with the bracelet attached.
- Ask for video of the crown threads and bezel rotation.
- Ask which movement is inside and its beat rate.
- Get the return window in writing.
Legal Note
Counterfeit watches infringe Omega and Swatch Group trademarks. US Customs and Border Protection seizes counterfeit goods at import. Selling a replica as genuine is fraud.
