Ultra Deep 6000m Replica Review: First Pick, Then Options
The Omega Seamaster Planet Ocean Ultra Deep carries a 6,000 m (20,000 ft) rating, a 45.5 mm case, a 15.5 mm profile, and Grade 5 titanium on the titanium references. The movement is the Co-Axial Master Chronometer 8912: 25,200 vph, 60 hours of reserve, 15,000 gauss magnetic resistance. Replica factories copy the shape, the dial print, and the bezel. They do not copy the depth rating. No replica of this watch ships with a 6,000 m certificate, and no factory pressure-tests a replica case to that number.
That gap sets the buying rules. A replica Ultra Deep is a look, not a dive instrument. Assume 30 m to 50 m of real water resistance after a gasket check. If you plan to swim, have a watchmaker test the case first.
Ultra Deep 6000m Replica Buying Guide
First pick: titanium-style case with clone 8912
Price range: $420 to $560. This tier copies the case shape, the domed sapphire, the ceramic bezel insert, and the titanium finish. The movement is a clone 8912 that beats at 25,200 vph with a 60 hour reserve, which matches the gen spec on paper. Date sits at 3 o'clock, same as the original. Weight lands near 110 g to 130 g on the bracelet. Buy this tier if you want the silhouette on the wrist for daily wear.
- Movement: clone 8912, 25,200 vph, 60 hour reserve
- Case: titanium look, brushed and polished mix
- Crystal: domed sapphire, check AR coating on the inside
- Water resistance: untested, treat as 30 m to 50 m
Option 2: steel case, clone 8912
Price range: $300 to $420. Same movement tier, steel case and bracelet instead of titanium. Weight jumps to about 180 g to 200 g. Omega does sell a steel Ultra Deep, so the story holds, but the steel rep sits heavier than the titanium reference most buyers picture.

Option 3: Miyota 9015, mid-tier case
Price range: $190 to $280. The 9015 runs at 28,800 vph with 42 hours of reserve. Date position and hand stack are correct, and the sweep is smoother than the clone 8912. Trade-offs: rotor noise, a thinner case, softer bezel action, and lume that fades faster. Good as a beater, weak next to a gen on a table.
Option 4: quartz and budget builds
Price range: $60 to $150. Skip these for this model. The case is too thin for the 45.5 mm Ultra Deep profile, the seconds hand ticks, and the dial print shows the gaps fastest on a large dial.
What to check on arrival
- Bezel alignment at 12 and backplay
- Crown gasket and screw-down threads
- Lume brightness on markers and hands
- Dial text weight and spacing
- Bracelet screw fit and clasp spring tension
How the tiers differ
Look at four points: caseback engraving depth, hand finish under a loupe, AR coating on the crystal, and serial engraving between the lugs. Tier one gets all four close. Tier three gets two.
Bottom line
Buy the titanium tier with the clone 8912 if the budget allows. It wins on weight, movement spec, and case finish. The 6,000 m number stays fiction in every tier, so plan the water resistance test before the first swim.
