A fake Air Command flyback is a replica of Blancpain's vintage-styled flyback chronograph, and one detail decides whether it is worth your money: the flyback itself. On the real watch you press the lower pusher at 4 o'clock while the chronograph is running, and the hands snap back to zero and start again in one motion. On most cheap replicas that pusher is decoration, or worse, a reset button that will jam the movement the first time you lean on it. Case shape, dial printing and lume all matter, but this is the first thing I check.
What the real Air Command is
Blancpain's Air Command traces back to a 1950s chronograph whose history is still debated, and the brand revived the name in 2019 with a modern reissue. The current version is a true flyback chronograph: the in-house automatic movement uses a column wheel and vertical clutch, which is what allows the instant restart without stopping first. That is not a cheap complication to build, and it is exactly where replicas fall down.
Why flyback is the hard part to copy
A standard chronograph works in three steps: stop, reset, start. A flyback does all of it with one push of the return pusher while the watch is still running. The mechanism needs a different lever arrangement and a clutch that can disengage and re-engage without shock. A replica factory can copy a case in a week. Copying that linkage so it survives daily use is a different problem, and most do not solve it.
How to test a flyback in under a minute
- Start the chronograph and let it run about 20 seconds.
- Press the 4 o'clock pusher once, while it is still running.
- Watch the central seconds hand. It should hit zero and immediately start counting again with no further input.
- If nothing happens, the pusher is a dummy.
- If it stops and sits at zero, you have a standard chronograph with a mislabeled pusher, and pressing it again may damage the movement.
- Repeat three or four times. Even a working flyback that feels gritty or needs a hard shove will not last.
Movement tiers you will run into
- Quartz. Thin and cheap, often with decorative subdials driven by separate steppers. No flyback, no feel, and the seconds hand ticks.
- Standard 7750-based automatics. These run the normal three-step sequence. The 4 o'clock pusher usually does nothing, or acts as a reset while running, which is the fastest way to break it.
- Modified 7750 or Seagull ST19 flyback conversions. Some sellers claim this. Ask for video of the sequence above, not photos.
- Higher-end replica flyback movements. They exist, but they sit in a different price bracket, and honest sellers say so upfront.
Dial and case tells
Count the registers first. The reissue is a two-register chronograph, so a replica with three subdials is copying a different watch entirely. After that, look at the bezel scale, the hand shape, and the crown guards. The genuine case is brushed with consistent finishing on the flanks, not just the top. Lume is the giveaway most people miss: the real one glows evenly across hands and markers, while fakes often have a brighter dial than hands, or a dull patchy glow. A replica built on a 7750 also tends to sit taller on the wrist, which you notice the second you strap it on.
Price expectations
If a listing offers a working flyback Air Command for the price of a plain chronograph, the flyback does not work. Real flyback mechanisms cost more to produce, and the replica supply chain reflects that. Budget for the tier you actually want instead of hoping a cheap one is secretly good.
One honest note before you buy
A replica is a replica. It will not pass a service, it will not hold value, and selling one as genuine is fraud. If you want the real thing, the brand's own specs and a reputable dealer are the only route. If you want the look and accept the tradeoffs, judge it on the flyback test above, because that single function is the entire point of the watch.
