Short answer
The Apollo 8 35th Anniversary is one of the harder Speedmasters to fake convincingly, and the reason is the movement. Omega blackened the whole caliber 1861 for this reference, and almost nobody in the replica trade bothers to reproduce that properly. So if you flip the watch over, look through the sapphire caseback, and see plain steel plates, you are not holding a genuine watch. Most "Apollo 8" fakes out there are ordinary Speedmaster clones with a swapped caseback and a story attached.
What the real watch is
Omega released the Speedmaster Professional Apollo 8 35th Anniversary in 2003, reference 3578.51.00, marking the December 1968 mission that first carried people around the Moon. It sits in the standard 42mm Speedmaster case, wears a black dial tied to the mission, and uses a sapphire caseback so the movement is on display. The 1861 inside is black-coated from the plates to the bridges. That single detail is what separates this reference from a regular Moonwatch on the wrist, and it is also the detail counterfeiters skip.
Case, crystal, caseback
- Caseback: sapphire, with the mission text engraved into the surrounding metal. Fake engraving sits shallow, wanders off line, or is simply printed on the glass.
- Pushers and crown: crisp threads, no sideways play, a signed crown with sharp edges on the Omega symbol.
- Crystal: domed sapphire with a clean edge and no distortion over the outer seconds track.
- Serial and reference: stamped at even depth on the caseback, and they should line up with the paperwork.
Weight and feel tell you a lot here. A genuine Speedmaster has a specific heft and balance, and the pushers snap back with authority. Cheap copies feel hollow and the chronograph pushers go mushy after a few presses.
The movement is the hardest thing to fake
On a real 3578.51.00 the black finish on the movement is even, satin in places and polished in others, and the engraving on the bridges is fine and readable. Fakes usually show one of three things: a standard steel-colored 1861 clone, a cheap black paint that looks gray or green under light, or a decorated plate that hides a quartz or basic automatic movement underneath. Open the caseback or have a watchmaker do it. Ten minutes of inspection settles the question.
Dial and lume
Dial printing on the genuine is razor sharp, and the hands are finished on every side, including the ones you only see when the light hits at an angle. Lume matters too. A real Speedmaster glows evenly and fades on a predictable curve. Replicas glow weak, patchy, or with a green tint that looks nothing like the original. Look at the subdial spacing as well, since many fakes use a movement with a different layout and the registers sit slightly off.
Price is the fastest filter
A genuine Apollo 8 35th Anniversary trades in the thousands, and clean examples with box and papers sit well above that. Anyone offering one for a few hundred dollars is not selling you an anniversary Speedmaster. That is the whole tell. Scarcity drives the price, and the fakes exist because people want the look without paying for it.
What I check first
- Movement color through the caseback. Black plates or walk away.
- Caseback engraving depth and font.
- Dial printing under a loupe, especially the text near the subdials.
- Lume behavior in a dark room.
- Box, warranty card, and pictograms card that match the reference number.
None of these checks requires special equipment beyond a loupe and a bright light. Do them in order and you will know within a couple of minutes.
