Short answer
The replica Air Command 6665 is a copy of the Blancpain Air Command chronograph, sold by dealers under a listing code. The original Air Command is a 1950s chronograph. Blancpain relaunched it in 2019. The number 6665 does not come from Blancpain. It is a dealer code. The same watch appears as Air Command 42mm, AC chrono, or Air Command titanium.
What the original is
Blancpain built the Air Command in the 1950s for military pilots. Published sources disagree on the exact run. Hodinkee and Blancpain describe a two-register chronograph with a countdown bezel and a case near 42mm. The 2019 relaunch used steel and titanium, with a flyback movement. Documented vintage examples number in the dozens. Auction prices reach six figures.
Air Command 6665 Replica Price Guide: What You Need to Know
What first copy means
Dealers split copies into tiers. First copy sits at the top of the Chinese market: 1:1 case shape, correct dial printing, sapphire crystal, and a movement that matches the original dial layout. Below it sit AAA and A grades with mineral glass, wrong fonts, and quartz movements.

Movements
Three movements show up in these copies.
Replica Air Command 6665 Watch Guide
- Seagull ST19. Hand wound, 21,600 vibrations per hour, about 40 hours of power reserve. A column-wheel design derived from the Venus 175.
- Seiko VK64 or VK67 meca-quartz. Battery timekeeping, mechanical chronograph pushers. Thinner and cheaper.
- Asian 7750. Automatic, thicker, adds a rotor.
Ask which movement sits inside before paying. The price gap between an ST19 build and a VK64 build is large.
QC checklist
- Subdial hands reset to 12. Ask for a video.
- Chronograph seconds hand sits on the 12 marker at rest.
- Bezel turns with even clicks and no back play.
- Case back engraving depth and font match the photos.
- Lume color matches between dial and hands. Request a dark photo.
- Crown threads engage without cross-threading. Most ST19 builds use a push-pull crown.
Price tiers
Meca-quartz builds run $80 to $150. ST19 builds run $200 to $400. Automatic 7750 builds run $350 to $600. Case material and strap move the number. A leather strap adds $20 to $40.
Care
Do not swim with it. Gaskets on copies are not pressure tested. Wind a hand-wound ST19 at the same time each day, about 20 turns. Keep it away from magnets and from drops on tile. Service is hard: most watchmakers refuse copies, and a replacement ST19 costs less than a repair.
What is not known
No factory publishes production numbers for these copies. The 6665 code is not standardized. Two sellers can use it for two different watches. Check the photos, not the code.
