Answer first: "replica type 21 flyback" means a copy of the Breguet Type XXI flyback chronograph. Breguet sells the line as Type XX. The XXI is the version with a flyback chronograph and a 42 mm case. Replica makers copy the case, dial and strap. Most copies do not copy the flyback mechanism.
What the name refers to
Breguet built the Type XX for the French naval air arm (Aeronavale) in the 1950s. The Type XXI came later, as a chronograph with an automatic movement. The steel model carries reference 3810. Breguet fits caliber 584Q.
A flyback chronograph does in one press what a standard chronograph does in three. Standard: stop, reset, start. Flyback: press the lower pusher while the chrono runs. The hands snap to zero and timing restarts in the same instant.
What copy watches get right
- Case diameter near 42 mm and the same lug shape.
- Dial layout: subdials, date window, printed markings.
- Sapphire crystal on the better grades.
- Strap width and buckle style.
Weight and case finishing are the parts that show the difference. Breguet bevels and polishes case edges by hand. A copy at a low price does not.
The movement problem
Most replicas use a clone of the Valjoux 7750, sold in Asia as the A7750. The 7750 has no flyback. It uses a cam and lever chrono system with stop, reset and start as separate actions. When a seller puts a 7750 clone in a Type XXI case, the lower pusher cannot do a flyback. On some builds the pusher does nothing. On others it stops the chrono.
Some sellers claim a "modified 7750 with flyback". Ask for a video test before paying. Steps:
- Start the chronograph with the upper pusher.
- Let it run ten seconds.
- Press the lower pusher once.
- Watch the central seconds hand. On a true flyback it returns to zero and keeps moving. If it stops at zero, the watch has no flyback.
Checklist before buying
- Movement name and a photo of the movement.
- Case diameter in mm, measured, not quoted.
- Function of each subdial.
- Water resistance claim. Treat it as a claim, not a rating.
- Return policy and payment method.
Price and limits
Listing prices for Breguet Type XXI replicas change with factory and movement. I have no verified survey data on current prices, so treat any quoted range as unconfirmed. Servicing is the longer problem. A watchmaker can source parts for a 7750 clone. A flyback module, if one is fitted, is harder to replace.
No replica carries Breguet finishing, a Breguet serial or Breguet service. Caseback engraving and movement decoration differ from the genuine watch. Buyers who want working flyback should look at the genuine reference or at a chronograph from a brand with spare parts supply.
