What Is a Type 21 Flyback Replica?
A Type 21 flyback replica is a copy of the Breguet Type XXI, a pilot chronograph built around a flyback movement. It reproduces the 42mm steel case, the fluted case band, the 24-hour ring, and the three-sub-dial layout that made the original a favorite of French naval aviators.

What separates it from an ordinary chronograph copy is the flyback action. One push of the lower pusher sends the chronograph hand back to zero and keeps it running, with no stop-and-reset step in between.
Type 21 Flyback Replica vs Original
Most buyers chase three things: a working flyback, a case size that suits a 7-inch wrist, and a dial that reads clean at arm's length.
How the Flyback Complication Works
A standard chronograph needs three presses to time back-to-back events: stop, reset, start. Flyback cuts that to one. The reset hammer strikes a heart-shaped cam, the hand snaps to zero, and the running train keeps the watch timing.
Type 21 Flyback Watch Comparison: Top Picks for Luxury Watch Enthusiasts
- Pilot use: time one leg of a flight, hit flyback, start the next leg with no pause.
- Mechanism: heart cam, reset hammer, and a coupling that stays engaged.
- Tell: the hand jumps to zero in one motion and restarts at once.
If the hand stops at zero and waits for another press, you are looking at a plain chronograph with a pusher that only looks the part. That flaw shows up on cheap Type 21 flyback replicas more than any other.
Specs to Compare Before You Buy
Ask the seller for numbers, not adjectives. These are the fields that decide whether a replica feels right on the wrist.
- Case diameter: around 42mm on the Type XXI pattern; 40mm and 44mm copies exist.
- Thickness: 12 to 14mm is normal for an automatic chronograph. Under 11mm points to a quartz module inside.
- Crystal: sapphire with a slight dome. Mineral glass scratches and shows up in photos.
- Dial: 24-hour ring, applied markers, and sub-dials at 3, 6, and 9.
- Lugs: 21mm or 22mm, so straps are easy to source.
- Weight: a steel automatic lands near 100g on a leather strap.
Movement Choices Inside Type 21 Flyback Replicas
Quartz Flyback Modules
This is the cheapest tier. Quartz copies keep time, and some reset with one push, but the second hand ticks and the case sits thin and light. Fine as a beater, weak as a collection piece.
Asian Automatic Chronographs
The middle tier uses a cam-actuated automatic chronograph movement with a flyback module or a rebuilt chronograph plate. Expect a smooth sweep, a 40-hour power reserve, and a pusher feel that is firm rather than crisp.
Clone-Grade Movements
Top replicas copy the layout of the original movement: column wheel or vertical clutch, decorated bridges, and a rotor that matches the reference. Service costs more and parts are harder to find, but the pusher action comes close to the real thing.
Case, Dial, and Crystal Checks
Look at the small details first, because they cost the factory money and they are where shortcuts appear.
- Marker alignment: every applied index should point at the center of the dial.
- Date window: centered in its aperture, with no gap at the edges.
- Pusher guards: machined, not stamped, with even gaps on both sides.
- Case back: engraving depth should be consistent and readable under a loupe.
- Lume: charge it with a phone light, then check that all markers glow at the same brightness.
What a Type 21 Flyback Replica Costs
Prices track the movement, not the name printed on the box.
- $80 to $150: quartz, mineral glass, light case, flyback action often faked.
- $200 to $400: Asian automatic chronograph, sapphire, decent dial work.
- $450 and up: clone-grade movement, better finishing, near-correct thickness.
A seller who asks top-tier money for a quartz watch is the clearest red flag in this market. Ask for a movement photo with the case back removed.
Water Resistance and Daily Wear
Treat any water resistance claim on a replica as a claim, not a fact. Gaskets are the first thing factories skip, so a watch rated at 50m may fog after a hand wash. Keep it away from pools and showers unless a local watchmaker has pressure-tested it.
Quick Buying Checklist
- Confirm the flyback works in a video, not in a product description.
- Match case diameter and thickness to the reference you want.
- Ask which movement is inside and who can service it.
- Check strap width so you can swap bands later.
- Buy from a seller with a return window, then inspect the watch in the first week.
FAQ
Does the flyback function work on every replica?
No. Many low-cost Type 21 flyback replicas use a standard chronograph movement with a pusher that mimics the look. Test it in person or on video before you pay.
Can a watchmaker service a Type 21 flyback replica?
Independent watchmakers can service common Asian chronograph movements and quartz modules. Clone-grade and unusual layouts may need parts the shop cannot order, so ask before you buy.
What strap fits a Type 21 flyback replica?
Most copies use 21mm or 22mm lugs. A brown or black leather strap with a deployant clasp matches the pilot look, and a fabric NATO works for casual wear.
