The short answer
Omega builds the Seamaster Planet Ocean Ultra Deep in a 45.5 mm case rated to 6,000 m of water resistance. Orange trim appears on the bezel scale, dial text, seconds hand, or strap, depending on the reference. Replica sellers list copies under the same keyword. Most copies match the case width. Many miss the 18 mm thickness, the crown hardware, and the depth rating.
Genuine specs to compare against
- Case diameter: 45.5 mm
- Case thickness: 18.1 mm
- Case material: Grade 5 titanium or stainless steel, by reference
- Water resistance: 6,000 m (20,000 ft)
- Movement: Omega Co-Axial Master Chronometer Calibre 8912, no date window
- Crystal: domed sapphire with anti-reflective coating on both faces
- Bezel: ceramic insert with the diving scale
Reference numbers change with case material, dial color, and strap. Omega's own catalog is the authority on which reference carries orange trim. Seller listings often borrow a number from a different model.
Orange accent details to check
Orange is the detail copies get wrong. Genuine orange lacquer on a seconds hand or bezel scale reads flat and matte in indoor light. Low-tier copies use glossy paint that shifts toward red or yellow under different lamps. Compare the orange against a daylight photo of the genuine dial. Look at the edge where orange meets black or white. Genuine printing stays crisp at 10x magnification. Copies show fuzzy borders and uneven fill.
What replica versions get wrong
- Thickness. A genuine Ultra Deep is 18.1 mm tall. Many copies sit at 14 mm to 16 mm because the factory reuses a standard Planet Ocean case.
- Crown height. Check the crown position against the case flank. Copies sit flush or protrude past the guards.
- Dial text. "6000m/20000ft" is printed on the dial. Copies misspace the line, use the wrong font weight, or drop a zero.
- Movement. The genuine watch runs Calibre 8912. Copies run a Miyota 9015, a Seagull ST21, or a decorated automatic with engraved rotor text.
- Weight. Grade 5 titanium is light for its size. A steel copy of a titanium reference feels heavy in the hand.
Water resistance claims
ISO 6425 sets the test standard for diver's watches. A 6,000 m rating requires a pressure chamber test at 125 percent of rated depth, or 7,500 m. No replica factory publishes that test data. Buyers who swim with a copy risk water entry at 30 m to 50 m. Gasket quality, crown thread condition, and caseback torque decide the real limit. No seller photo proves a depth rating.
Legal status in the United States
Counterfeit watches are illegal to import and sell in the United States. 18 U.S.C. 2320 sets criminal penalties for trafficking in counterfeit goods at up to 10 years in prison and a $2 million fine for a first offense by an individual. 19 U.S.C. 1526 allows U.S. Customs and Border Protection to seize and destroy counterfeit merchandise. Watches and jewelry rank among the top seized categories at U.S. ports. A shipment from overseas can be seized, and most sellers do not refund the buyer.
How to check a listing
- Ask for the reference number and compare it to Omega's catalog.
- Ask for a caliper photo of the case thickness.
- Ask for a caseback photo showing the model number.
- Compare the orange hue to a daylight photo of the genuine dial.
None of those steps confirm water resistance. Treat any depth claim on a replica as unverified.
