Answer first
"Ultra Deep orange" is the nickname sellers use for the Omega Seamaster Planet Ocean Ultra Deep with orange accents on the bezel and dial. The genuine watch is a 45.5 mm titanium dive watch rated to 6,000 m. Replica versions of this model list at about $85 to $600. The price gap tracks three things: case finishing, bezel insert material, and the movement inside.
Genuine specs to compare against
- Case: 45.5 mm, grade 5 titanium
- Thickness: 18.1 mm
- Water resistance: 6,000 m, tested at that pressure by Omega
- Crystal: domed sapphire, about 5.2 mm thick
- Movement: Omega calibre 8912, co-axial, Master Chronometer certified, 60 h power reserve, 15,000 gauss magnetic resistance
- Caseback: titanium with a diver medallion and dive record engraving
- Bezel: unidirectional, ceramic insert, orange markings on the orange variant
Reference numbers for the orange version differ by year and market. Confirm the exact reference with the seller before you compare photos, since the Ultra Deep line includes blue, black, and white dial versions with different bezel colors.
Replica tiers
Low tier, $85 to $150
Steel case with a titanium look coating. Case thickness often runs past 18 mm. Bezel insert is painted or thin aluminum. Dial print sits heavy. Lume is weak and fades in under an hour.
Mid tier, $200 to $350
Closer case shape. Ceramic or ceramic-like bezel insert. Better dial print and applied markers. Date font is often wrong. Crown threads feel rough. Helium escape valve is usually decorative.
High tier, $400 to $600 and up
Titanium or titanium-alloy case on some batches. Sapphire crystal with inner anti-reflective coating. Clone or modified automatic movement with a decorated rotor. Caseback engraving depth comes closer to the original. Bracelet end links fit tighter.
Checks before you pay
- Ask for a caliper photo of case thickness. Anything past 18.5 mm wears different on the wrist.
- Ask for a short video of the bezel turn. Count the clicks and listen for slack at 12 o'clock.
- Check the date window position and font against a genuine photo.
- Ask if the crown screws down without cross-threading.
- Request a lume shot taken 30 seconds after light exposure and another after 10 minutes.
- Confirm the movement type in writing. Sellers swap movements between batches.
- Ask for the bracelet clasp code and the end link fit photo.
What replicas do not match
No replica carries a 6,000 m rating. Published pressure test data for replica cases does not exist. Grade 5 titanium grain and the matte brushed finish on the genuine case are hard to copy at low cost. The 5.2 mm sapphire and the deep caseback engraving are the other two gaps that show under close inspection.
Water and wear limits
Treat any replica as splash resistant at best. Gaskets on low and mid tier cases are not rated, and pressure testing a counterfeit case is not worth the risk. Remove the watch before swimming.
Legal position in the US
A watch that carries a protected trademark without authorization is a counterfeit good. Sale is illegal, and U.S. Customs and Border Protection seizes counterfeit shipments at import. Buyers carry the loss when a parcel is stopped. Payment methods used in this market rarely offer a refund path.
Unknowns
Batch-to-batch changes in case metal and movement supply are not published. Ask the seller for the current batch specs and keep the reply in writing.
