An omega ultra deep clone watch is a replica of the Seamaster Planet Ocean Ultra Deep, the 6,000 m titanium dive watch Omega added to its lineup in 2022. The better clones match the 45.5 mm case, the blue-to-black gradient dial, the ceramic bezel and the domed sapphire caseback. What they do not match is the depth rating. No replica ships with a factory pressure test to 6,000 meters.
What Is the Omega Planet Ocean Ultra Deep?
It is Omega's deepest production dive watch. The spec sheet lists a 6,000 m (20,000 ft) rating, a 45.5 mm case in grade 5 titanium, a helium escape valve, and the Master Chronometer Caliber 8912 with a 60-hour power reserve and 15,000-gauss magnetic resistance. The case runs about 18 mm thick, so it sits tall on the wrist.
Omega built the watch after sending prototype cases to the Challenger Deep in 2019 with the Five Deeps Expedition. The production version arrived three years later. That backstory, plus the odd case shape and the see-through caseback, made it a target for replica factories.
How Close Is an Ultra Deep Clone to the Real Thing?
Close in silhouette, looser in the details. A top-tier clone reads as an Ultra Deep from across a table. The gaps show up in thickness, materials, movement quality and sealing.
Case and Dimensions
Most listings quote 45.5 mm, matching the genuine spec. Measured thickness often runs 1 mm to 2 mm over the real 18 mm, and a steel case weighs more than the titanium original. Titanium clones exist in grade 2 and grade 5, but they cost more and fewer factories build them.
Dial, Hands and Bezel
The gradient dial is the hardest part to copy. Cheap versions paint a flat blue and skip the fade to black at the edges. Look for applied indices with clean edges, a date font that matches the genuine, and a ceramic bezel insert rather than painted aluminum. Lume is the other tell: budget clones glow for an hour, good ones hold most of the night.
Movement
Most clones run a Miyota 9015, a Seagull or a Hangzhou automatic under a decorated rotor shaped like the 8912. The 28,800 vph beat rate matches, so the seconds hand sweeps the same way. Power reserve lands near 40 hours instead of 60, and there is no METAS certification or anti-magnetic cage inside.
The Caseback
The genuine watch uses a domed sapphire caseback shaped like a diving bell. Clones use a flatter dome with thinner sapphire and printed text where the original is engraved. Hold the watch at an angle and the difference in depth is easy to spot.
Can a Clone Handle 6,000 Meters of Pressure?
No. Depth ratings come from case geometry, gasket quality, crystal thickness and a pressure test at the factory. Replica makers skip that test. Many clones marked "50 m" leak in a swimming pool, and the 6,000 m engraving on the caseback is decoration.
If you plan to wear one near water, take it to a local watchmaker for a pressure test first. Plenty of them will fail, and a failed test costs less than a flooded movement.
What Should You Check Before Buying an Ultra Deep Clone?
- Ask for dated photos, not factory renders. Photos show what a render hides.
- Ask which movement is inside and who builds it.
- Ask for measured case thickness and weight on a scale.
- Request a lume shot in a dark room and a macro shot of the dial printing.
- Watch a video of the bezel turning. A gritty, loose click points to a budget build.
- Confirm the return policy, the shipping method, and who covers seizure at customs.
How Much Do Ultra Deep Clones Cost?
Prices track factory tier. Entry builds sit near $200, mid-tier examples run $300 to $450, and the best finished ones pass $600. Titanium cases and Swiss-movement swaps push a clone toward the top of that range. Since the genuine Ultra Deep sells for five figures, the gap stays wide at every level.
What Are the Usual Tells on a Replica Ultra Deep?
- Thickness over 19 mm and a case that sits too high on the wrist.
- Crown threads that feel rough after a few turns.
- Date wheel font that is too bold or sits off-center.
- Lume that fades within the first hour.
- Bracelet end links that rattle against the case.
- Shallow caseback engraving and a thin sapphire dome.
Is It Legal to Buy a Clone Watch?
Rules vary by country, and the border is where it matters. US Customs and Border Protection can seize counterfeit goods on import, and selling them is a trademark violation. Buyers in the US and EU risk losing both the watch and the money. Check your local rules before you order.
Who Is the Ultra Deep Clone For?
Buy it for the look. The case shape and the 6,000 m story are the appeal, and a good clone delivers both for a fraction of the price. Do not buy it as dive gear, as an investment, or as a stand-in for a real Seamaster on a collector's shelf.
If water resistance you can trust matters more than the design, a stock Seiko or Citizen diver costs about the same and comes with a warranty. That trade is worth a minute of thought before you spend the money.
