Quick answer
The Blancpain Air Command has a short production history and a high resale price, so copies exist in every quality tier. An original matches Blancpain's published reference data in case diameter, dial print, movement family, and caseback engraving. Any single mismatch is enough to walk away. The 1950s original and the modern re-edition are different watches, so authenticate the exact reference you are offered, not "an Air Command" in general.

Before you start
- Blancpain reference data or a printed catalog for the exact reference in question.
- A digital caliper, a 10x loupe, a bright light, and a steady surface.
- A watchmaker who will open the caseback in front of you.
- Photos of a known original of the same reference for side by side comparison.
Steps
- Identify the reference number first. Ask the seller for the reference and the serial, then find that exact reference in published Blancpain data. A reference that does not exist in the catalog ends the process.
- Measure the case with a caliper across the bezel, not the crown guards. Compare the reading to the published diameter. A modern Air Command in the wrong diameter, or a watch sold as vintage that measures like a modern case, is not original.
- Examine the dial print under the loupe. Check the weight of the brand name, the spacing between the subdials, and the shape of the numerals. Copies use flat, thin print, and subdial spacing drifts because the base dial was made for a different movement.
- Check the hands and the lume. Original hands have an even finish and crisp edges. On a vintage piece, the lume should age in step with the dial plots. A dial with cracked, browned plots and hands with fresh lume points to a rebuild or a copy.
- Test the chronograph. Start, stop, and reset it several times. The pushers should feel firm and return with a clean click. Flyback behavior on a reference that has it should reset with no stutter.
- Inspect the caseback engraving with the loupe. Original engraving is cut into the metal with consistent depth and sharp edges. Shallow stamped or laser etched text on a steel case signals a copy case.
- Have a watchmaker open the case. Compare the movement family, the finish, the rotor engraving, and the jewel count against the specification for that reference. A generic chronograph movement under a branded rotor is proof of a fake.
- Verify the box, papers, and service records. Confirm that the serial on the paperwork matches the case and the movement. Modern Air Command pieces were sold in small runs, so a documented chain of ownership is typical at this price.
Red flags
- Price far below the current market for that reference.
- Seller refuses to let a watchmaker open the caseback.
- Serial on the papers does not match the case or the movement.
- Listing text leans on "genuine parts" or "same factory" wording.
- Photos traced back to another seller or another watch.
