A replica Speedmaster Apollo is a Chinese-made copy of Omega's Moonwatch, typically built on the 42mm Professional case and sold anywhere from about $80 for quartz versions to $400–$600 for the better mechanical ones. Here is the short answer: the case, dial, and bezel can look convincing at arm's length. The movement never will be. Inside you get a Seagull ST19, a modified Valjoux 7750, or a quartz module, and every one of those choices changes the thickness, the subdial placement, or both. If you want the Apollo look on your wrist, a rep gives it to you. If you want the watch, it does not.

Which Apollo references get copied most

The plain Speedmaster Professional, the hesalite Moonwatch with the black step dial and the dot-over-90 bezel, is the most cloned reference by a wide margin. After that come the anniversary editions: the Apollo 11 50th Anniversary with its ceramic bezel and gold accents, and the Silver Snoopy variants. Those are harder to fake well because the details people check are the expensive ones. A gold Ceragold tachymeter scale, a Moonshine gold medallion in a subdial, an animated caseback, these are the parts a $150 copy cannot reproduce. Anniversary reps sell on the story, not the execution.

The movement decides the shape of the watch

A genuine Moonwatch is a hand-wound chronograph around 13.5mm thick, and that number is not cosmetic. Reps built on a 7750 usually run 2mm thicker because the automatic rotor and its works have to go somewhere. Reps built on the ST19 stay closer to the right profile and keep the hand-wind feel, which is why the ST19 versions are the ones collectors of reps actually talk about. The tradeoff shows up in the subdials. The ST19 has its own geometry, so the spacing between the three registers almost never lands exactly where Omega puts them. On a wrist nobody notices. Under a loupe or in a photo next to a real one, it is the first thing that reads wrong.

Details that give a rep away

• Subdial spacing and the depth of the recess, which is usually too shallow.
• Case thickness, especially on automatic versions.
• The bezel font and the dot-over-90, often slightly too heavy or too thin.
• Crystal material. Real hesalite has a warm, slightly soft look that sapphire and coated mineral do not match.
• Applied logo edges, which tend to be rounded on reps and crisp on the original.
• Bracelet end links that do not sit flush against the lugs.
• Lume that glows green when it should be a warmer tone.

Price tiers and what changes

Under $100 you are looking at quartz, and often a faux chronograph where the pushers do nothing but move a decorative hand. From about $150 to $300 you get a working ST19 or a lower-grade automatic with a decent dial print. Above $400 the case finishing, bracelet, and dial text improve noticeably, and that is where reps start to survive a side-by-side glance. None of these tiers get you a column wheel chronograph with the same architecture as the calibre 1861. That mechanism is not something a factory reproduces at these prices.

The legal and practical side

Counterfeit watches are illegal to import into the United States, and Customs can seize a package. Selling them is a trademark violation with real exposure. On the practical side, service is the quiet problem: no watchmaker wants to source parts for an unmarked Chinese movement, and a failed chrono module often means the watch is done. Water resistance on reps is also a guess unless someone actually pressure-tested it. Treat a replica as a costume piece with a lifespan, not an heirloom, and the expectations stay honest.
