Replica Speedmaster Grey Side of the Moon
The replica Speedmaster Grey Side of the Moon copies Omega reference 311.93.44.51.99.001. Omega released the watch in 2014. The case measures 44.25 mm. It is grey ceramic, not steel. The dial is sandblasted grey ceramic. The bezel carries a tachymeter scale filled with Liquidmetal. The movement is the Omega calibre 9300, an automatic chronograph with a 60 hour power reserve. US list price sat in the five-figure range.
Replica output for this reference runs from low grade to high grade. Prices run from about $100 to $800. No replica carries a 9300 movement. Most copies use a Chinese automatic chronograph or a 7750 pattern movement with decoration.
Case Material and Weight
Grey ceramic is the first tell. The genuine case has a matte sandblasted surface and no metal sheen. Replica cases are steel, aluminum, or coated alloy. Steel is denser than ceramic, so a steel copy weighs more on a scale. Ask the seller for a photo of the watch on a scale, then compare that number with a genuine listing. Case thickness is another tell. Ask for caliper photos at the case side.
Bezel and Tachymeter Scale
Liquidmetal is a bulk metallic glass. Omega bonds it into the ceramic bezel, so the numbers and markers sit flush with the surface. Replica bezels use a steel insert with printed or etched numerals. Look for a glossy insert, raised paint, uneven fill, and a scale that does not match the angle of the genuine bezel.
Dial and Subdials
The 9300 chronograph has two subdials. Running seconds sit at 9 o'clock. The combined hour and minute counter sits at 3 o'clock. A 7750 pattern movement has three subdials at 12, 6, and 9. Count the subdials in every photo. Date window placement changes with reference. Match it to photos of the exact reference number you are offered, and ask the seller for that number in writing.
Caseback and Movement Claims
Sellers label copies as clone 9300, 1:1, or Swiss made. These labels do not describe the movement inside. The 9300 has a column wheel, a co-axial escapement, two barrels in series, and a silicon balance spring. Check the caseback in photos. Compare the engraving, the reference number, and the crystal type with photos of the real watch. If the case has a display back, ask for a video of the movement running.
