Short answer

A replica Type XX chronograph copies Breguet's French naval aviator chrono. It is not a Daytona with a different dial. That distinction drives everything: the real Type XX is a flyback, and no replica on the market, at any price tier, reproduces a working flyback. What you buy is a watch that reads correctly on the wrist and inside a photo, usually powered by a hand-wound Seagull ST19 or an Asian 7750, with a pusher feel that gives the game away the first time you use it.

What the watch actually is

Breguet built the Type 20 for the French air force starting in the 1950s, then sold a civilian version as the Type XX. The modern line runs from the 39mm ref. 3800 through the 42mm Type XXI 3810, up to the 2023 Type XX ref. 2067 with the calibre 728. Black dial, Arabic numerals, lume on the hands and markers, and a chronograph you can reset and restart with a single push of the lower pusher.

The 3800 keeps the classic 3-6-9 subdial layout. The Type XXI moved the minute counter to a central hand and added a 24-hour indicator, which changes the dial in a way that is hard to fake.

Why the flyback never shows up in a replica

Flyback means the chronograph returns to zero and restarts on one pusher press, with no stop in between. That needs a specific lever mechanism inside the movement. The ST19 does not have it. The A7750 does not have it. Quartz modules definitely do not have it. So every Type XX replica, whatever the listing claims, is a standard start-stop-reset chronograph wearing Type XX clothes. If a seller writes "flyback" in the description, that is a copy-paste error or a lie.

Movement tiers you will run into

  • Quartz. The cheapest tier. The chronograph second hand ticks once per second and the subdials jump instead of sweeping. Anyone who has handled the real thing spots it instantly.
  • Seagull ST19. Hand-wound, column wheel, smooth sweep. This is the sweet spot for most buyers. Light pusher click, no flyback.
  • Asian 7750. Automatic, heavier, and the movement most reps use when they advertise an automatic chronograph. Subdial functions often differ from the real layout, and servicing is a real cost.

What I check before buying

Ask for photos with the chronograph running and the watch angled, not flat and straight on. Then look at these:

  • Subdial spacing. On reps the counters sit too close to the center or too far out, and that gap is the easiest tell in person.
  • The central hand on Type XXI versions. Many reps fake it with a glued hand or a 12-hour hand that does nothing.
  • Dial print. Weight and spacing of the signature, the position of the Swiss Made text, and whether the numerals are applied or printed.
  • Caseback engraving. Font weight and depth on the reference and serial numbers.
  • Bezel type. Coin edge versus smooth, and whether it matches the reference being copied.
  • Crystal. The real one is domed sapphire with decent anti-reflective coating. Reps often ship flat with a blue tint.
  • Pusher feel. Screw-down pushers should thread cleanly. Gritty threads point to a cheap case.

Wrist feel and sizing

The 39mm 3800 wears like a vintage chrono, which suits smaller wrists and looks right on leather. The 42mm Type XXI and the 2067 sit bigger and heavier, and reps rarely match the real case thickness. Expect a millimeter or two of extra bulk, which changes how the watch sits under a cuff. Lug width varies by reference, so buy the strap after the watch arrives, not before.

What it will not fool

Anyone who handles Breguet regularly spots the case finishing first. Real cases have crisp bevels and polished flanks that catch light a certain way; reps have softer edges and slightly hazy brushing. Movement finishing behind a display back is another giveaway, since the ST19 is a plain, industrial-looking movement.

The honest summary: a Type XX replica is a look-and-feel purchase. Buy it for the dial, the strap, and the wrist presence. Do not buy it expecting the function that gives the real watch its name.
