The Grey Side of the Moon is one of the harder Speedmasters to copy well, and that is exactly why you should be picky. The real watch is a ceramic case, not a steel case with grey paint on it. If the case material is wrong, nothing else on the watch can rescue it. I start every comparison right there.

My pick, in one line
Buy the version with a real grey ceramic case and a working chronograph layout. In today's market that means the top-tier builds from the factories that also produce the Dark Side of the Moon, usually listed with a clone 9300 or a modified 7750 hiding under a decorated plate. Budget somewhere between $450 and $700. Anything cheaper is a compromise on the single feature that defines this watch.

Why the case decides everything
Material and weight
Zirconium-oxide ceramic is lighter than steel and it shrugs off the hairline scratches that steel collects. A ceramic-coated steel case feels dense in the hand, and after a few months it shows grey chips at the lugs and crown guards where the coating wears through. I check weight first, then look at the lug edges under a lamp. Real ceramic keeps the same sandblasted grey from every angle. Coated steel goes flat and slightly blue in dim light.
Chronograph layout
The original runs calibre 9300: small seconds at 9, a combined hour and minute counter at 3, date at 6. Plenty of fakes take a standard 7750 and put hands where the registers should be, so a hand that should total elapsed hours just ticks along with the seconds. Test it before you buy. Start the chrono, let it run a few minutes, and note which hand does what. If the hands at 3 and 9 move in lockstep, the layout has been faked.
Grey Side of the Moon Replica vs Original Watch Comparison
Dial, hands and lume
The grey dial carries a fine grained texture. Cheap copies print or stamp that surface, so it looks flat or, worse, glossy under a phone flash. The hands should be brushed with a white lume fill that sits level inside the frame. Squint at the subdial rings. On a good build they are crisp and cut. On a bad one they are printed circles with soft edges.
Bezel, crystal and caseback
The tachymeter scale should sit flush in the ceramic insert, not printed on top of it. The crystal is sapphire with anti-reflective coating on both faces, which is why the dial looks almost invisible from an angle. Flip it over: the caseback should be sapphire with a decorated movement, clean engraving, and the ceramic marking on the case. Blurry text is the fastest tell on a budget build.
The options, ranked
- Top tier, roughly $450 to $700. Solid ceramic case, correct bi-compax layout, sapphire both sides, tidy engraving. This is the one I would buy. It nails the weight and the light response, which is what people actually notice on a wrist.
- Mid tier, roughly $250 to $380. Usually ceramic-coated steel with a decent dial and a working 7750. Looks right across a table, feels wrong in the hand, and the coating will eventually wear at the edges.
- Budget, roughly $120 to $200. Painted steel case, printed dial texture, mismatched chrono hands. Fine if you want the silhouette for a costume, useless if you care about the watch the original is.
What I check before I pay
- Weight in the hand compared to a steel chronograph of the same size.
- Chrono hands doing the correct job when the pushers are pressed.
- Lug edges and crown guards for any sign of chipped coating.
- Dial texture under direct light, not just room light.
- Caseback engraving sharpness and the movement finish behind the sapphire.
- Strap hardware: the folding clasp should feel tight and match the case tone.
The honest part
A replica is not a Grey Side of the Moon. It is a watch shaped like one, and it will never hold value, never see an Omega service bench, and should never be sold to anyone as the real thing. Buy it because you like the look of a grey ceramic Speedmaster and you want that look at a fraction of the price. That is a fair reason. Pretending otherwise is not.
Bottom line
Spend once on the ceramic-case build and skip the two tiers below it. The whole appeal of this watch is the material and the way it swallows light. A coated steel copy loses that the moment you pick it up.
