The VSF Omega Planet Ocean Ultra Deep replica is the top pick. It copies the 45.5mm Grade 5 titanium case, the Manta-style lugs, and the tall case back that defines the real 6000m diver. The OMF build is the runner-up for buyers who want the same silhouette and a lower price.

What Makes the Ultra Deep Hard to Copy?
The genuine Ultra Deep is a saturation diver built for 6000m, so every part has a job. Replicas copy the outline and skip the engineering behind it. The gap shows up in three spots.
omega planet ocean ultra deep replica review
- Case material: The real watch uses Grade 5 titanium, which is light and warm on the wrist. Cheap replicas use 316L steel that feels dense.
- Case back: The genuine sits tall to handle pressure. Some replicas flatten it, which changes the side profile.
- Crown guards: The genuine has sharp, angled guards. Soft, rounded edges are the fastest tell on a replica.
VSF vs OMF vs Budget Steel: Quick Comparison
Three tiers cover most of the market, and each one trades something for the price.
replica omega planet ocean ultra deep for sale
- VSF Ultra Deep: Titanium case, decorated clone movement, ceramic bezel insert with filled markers, solid end links. Best dial texture and best case finishing. Highest price of the three.
- OMF Ultra Deep: Titanium-look case (often steel with a matte finish), reliable automatic movement, decent bezel action. Softer lume and a flatter dial. Mid price.
- Budget steel: Steel case, standard Miyota-style automatic, printed or decal dial details. Heavier on the wrist and loud bezel clicks. Lowest price.
How Close Is the Case and Weight?
Titanium is the whole point of this watch. A 45.5mm steel case weighs far more, and that mass sits high on the wrist. If weight matters to you, spend the money on the titanium build.

Diameter on the good replicas lands at 45.5mm, with a lug-to-lug near 52mm. That is a large watch, and it wears large. A wrist under 7 inches will see the lugs overhang.
Dial, Bezel, and Lume
The Ultra Deep dial is matte black with a faint gradient and applied markers. The best replicas get the marker shape right and use a domed sapphire with an inner anti-reflective coating, which kills glare at an angle.
Lume is where money shows. Cheap builds glow green and fade inside an hour. Better builds use a blue-green mix that stays readable for hours.
- Check the marker rings. Painted rings look flat. Applied rings catch light.
- Check the bezel insert. Ceramic has a deep gloss. Aluminum looks dull.
- Check the helium valve. On good replicas it is a real screw-down part, not a glued cap.
Movement: What Runs Inside?
Most Ultra Deep replicas run a decorated automatic, often an Asian 2824 or a Miyota 8215 with a rotor plate shaped like the Omega 8912. Accuracy lands near minus 10 to plus 20 seconds a day on a fresh example, and that number drifts with wear.
The genuine 8912 is a Master Chronometer with a 60-hour reserve and magnetic resistance to 15,000 gauss. No replica matches that. Treat the movement as a working automatic, not a lab instrument.
Can You Swim With a Replica Ultra Deep?
No. Do not dive, and think twice about the pool.
Factories seal these cases for looks, not for pressure. Gaskets sit dry for months in transit, and the crown threads are the weak point. If you want water use, have a watchmaker pressure test the case and swap the gaskets first.
Even then, the 6000m figure on the back means nothing on a replica. That number is cosmetic.
Strap and Bracelet Choices
The real Ultra Deep ships on a titanium bracelet or a rubber strap with a titanium buckle. Replica bracelets use steel or titanium-look links with a stamped clasp. Rubber options on good builds feel soft and taper at the lugs.
A rubber strap cuts weight and hides any finishing gap at the lugs. It also makes the 45.5mm case sit closer to the wrist.
How Big Is It Next to Other Seamasters?
The Ultra Deep sits at the top of the Planet Ocean line for size.
- Planet Ocean 39.5mm: The small option. Fits most wrists and looks formal.
- Planet Ocean 43.5mm: The standard diver. A middle ground between desk and boat.
- Ultra Deep 45.5mm: The largest. Built for thick wetsuits and big wrists.
Which Ultra Deep Replica Should You Buy?
- Buy VSF if you want the closest match to the real 6000m diver and you plan to wear it often.
- Buy OMF if you want the look at a lower price and you accept softer details.
- Buy budget steel if the watch is a novelty and the extra weight does not bother you.
What to Check Before You Pay
- Ask for photos of the exact watch, not factory renders.
- Confirm the case material in writing.
- Request timegrapher numbers if the seller offers them.
- Confirm which straps and bracelets come in the box.
- Ask about the warranty and the return window.
FAQ
Is the Ultra Deep replica worth it?
Yes, if you want the size and titanium feel of a 6000m diver without the real price. Skip it if you need a tool watch that survives salt water.
How can you tell a fake Ultra Deep?
Look at the crown guards, the case back depth, and the lume. Sharp guards, a tall case back, and a long blue glow point to a better build.
What wrist size fits a 45.5mm Ultra Deep?
Seven inches is the floor. Below that, the lugs overhang and the watch looks borrowed.
Does the replica have a helium escape valve?
On VSF and OMF tier watches the valve is a real screw-down part. On cheap builds it is a decorative cap.
How much does an Ultra Deep replica cost?
Prices spread across three bands, from a low steel build to a titanium clone. Ask your seller for the current number, since bands shift.
Pick the titanium version if this is a daily wearer. The look reads the same at arm's length, and the weight is the part your wrist notices.
