Buy the replica that copies the reference you will actually wear, not the one with the longest spec sheet. The Speedmaster Moonwatch is a 42 mm hand-wound chronograph with a tachymeter bezel and a domed crystal. The Planet Ocean is a 600 m dive watch with a unidirectional bezel, screw-down crown and helium escape valve. The Ultra Deep is a 45.5 mm titanium dive watch rated to 6000 m with a domed sapphire and a closed caseback. Those are three different silhouettes, and a replica only feels right when case thickness, lug spacing and crown position track the original. Pick the shape first, then judge the copy on case finishing, bezel action, dial printing and movement type.
Omega Speedmaster, Planet Ocean, or Ultra Deep: Replica Buying Guide
Know which model you are buying
The Speedmaster is a chronograph, so the pushers, sub-dial spacing and crystal profile carry the look. A weak copy gets the sub-dials too close to the center or prints the tachymeter scale too thick. The Planet Ocean lives or dies on its bezel: ceramic insert, crisp dive scale, firm 120-click action with no back play, and a helium valve that sits flush. The Ultra Deep is the hardest to copy because of its depth rating hardware. The real watch has no helium escape valve, uses a domed sapphire thick enough to survive pressure, and wears large at roughly 18 mm tall.

What to check before you commit
- Case dimensions. Compare diameter, thickness and lug-to-lug against published brand specs. A replica that is 1.5 mm thicker than the original sits differently on the wrist and looks wrong under a cuff.
- Crystal and coating. Sapphire should be clear at an angle, not milky. Weak anti-reflective coating is the fastest tell on a cheap copy.
- Bezel action. Turn it through a full rotation. It should click at even intervals, align at 12, and have no vertical play.
- Dial print. Check logo weight, marker lume fill, date font and date window position. Crooked markers are common on budget tiers.
- Bracelet and end links. Solid links, tight end-link fit, working micro-adjust clasp, and no sharp edges on the underside.
- Movement. Manual wind for the Speedmaster, automatic with a smooth sweep for the dive models. Ask what the movement is based on so you know whether parts exist for service.
Spec bands worth knowing
- Speedmaster Moonwatch: 42 mm case, about 13.5 mm thick, 20 mm lugs, manual wind, roughly 50 hours of reserve, hesalite or sapphire crystal, 50 m water resistance rating.
- Planet Ocean 600M: 39.5 mm, 43.5 mm or 45.5 mm case, about 16 mm thick at the mid size, automatic, roughly 60 hours of reserve, 600 m rating, helium escape valve at 10 o'clock.
- Ultra Deep: 45.5 mm case, about 18 mm thick, titanium, 6000 m rating, closed caseback with an engraved motif, no helium valve.
- Common movement figures: 21,600 to 28,800 vibrations per hour, 40 to 70 hours of power reserve, hacking seconds on better grades.
Common pitfalls
Depth ratings are the biggest trap. A replica may carry a 600 m or 6000 m dial marking without gaskets or case testing to support it, so treat water contact as a risk until a watchmaker pressure tests the case. Helium escape valves on copies often do not seal or do not vent, which makes them decoration only. Oversized cases are another issue: some Ultra Deep copies add height that the original does not have, and the watch becomes top heavy on a titanium bracelet that is too light to balance it.
Finishing shortcuts show up in the details. Brushed and polished transitions on the lugs should be crisp, not washed out. Crown threads should engage without grit. Lume should glow evenly across all markers and fade at the same rate. On chronographs, test the pushers: start, stop and reset should feel distinct, and the reset should snap the hands back to zero without drift.

In the US, selling counterfeit goods is illegal and passing a replica off as an original is fraud, so keep the purchase for personal wear and expect no brand warranty or service support.
FAQ
Can a replica dive watch go in the water?
Only after a pressure test. Ask a watchmaker to check gaskets, crown seals and caseback torque before swimming. Many copies leak at the crown or caseback even when the dial claims a high rating.
Hesalite or sapphire for a Speedmaster replica?
Hesalite gives the warmer, domed look of the classic Moonwatch and picks up hairlines. Sapphire resists scratches and shows the movement through a display back on some versions. Match the crystal to the reference you want.
How do I judge bezel quality in a minute?
Rotate it fully, listen for even clicks, check alignment at 12, then press down on the insert to feel for vertical play. A loose bezel with soft detents is a sign of a low grade build.
Is the Ultra Deep too large for daily wear?
At 45.5 mm and about 18 mm thick it suits larger wrists and reads as a statement piece. Try a 42 mm diver first if you wear slim cuffs or prefer a low profile.
Can a replica be serviced?
Often yes if the movement is a common clone with available parts. Confirm the movement family before buying, since oddball movements can be impossible to repair.
