Core buying advice
For a 5th gen knockoff Speedster 1957, buy the version with a mechanical chronograph movement, a sapphire crystal, and a case that matches the original 1957 Speedmaster proportions. Skip any listing that uses stock photos, hides movement details, or refuses a QC video. The 5th gen label means little on its own. The seller must show the actual watch you will receive.
Duplicate Speedster 1957 5th Gen: The Ultimate Guide
What to look for
- Case: 38.6 mm to 42 mm diameter, 12 mm to 14.5 mm thick, 19 mm to 20 mm lug width. Check lug shape, crown guards, and pusher profile.
- Dial: broad arrow hands, applied logo, sharp print, and correct subdial spacing. A date window at 3 o'clock is a mismatch for a 1957 style no-date dial.
- Bezel: tachymeter scale with correct font and spacing. Steel or aluminum insert must sit flush and align at 12 o'clock.
- Movement: mechanical chronograph with 21,600 or 28,800 vph. Ask for a timegrapher video and a chronograph reset test.
- Crystal: sapphire with inner anti-reflective coating. Check for a domed profile that matches the era.
- Lume: vintage tone, even application, and a glow that lasts at least a few hours. Mismatched hand lume is a common tell.
- Water resistance: 30 m to 100 m. Do not swim unless the seller pressure-tested the seals.

Pitfalls
- Stock photos and no QC images.
- 5th gen used as a label with no proof of version.
- Quartz movement sold as mechanical.
- Mineral glass sold as sapphire.
- Wrong subdial spacing or an added date window.
- Short hands, flat lume, or a bezel that does not align.
- Sellers who demand payment methods with no recourse.
- Customs seizure and legal risk. In the US, selling counterfeit goods is illegal. Buying for personal use can still lead to loss of the item. Check local laws.
FAQ
Is 5th gen better than 4th gen?
Not always. Compare the specific movement, case, dial, and crystal. A well-built 4th gen can beat a sloppy 5th gen.
What movement should I expect?
A mechanical chronograph with 21,600 or 28,800 vph. Ask for a timegrapher video before you pay.
Duplication Speedster 1957 5th Gen: What the Label Means
How do I check the case size?
Ask for caliper photos. The target range is 38.6 mm to 42 mm.
Can I wear it in water?
Only if the seller tested the seals and rated it. Even then, keep it out of hot water and salt water.
What about QC photos?
Request clear, dated photos of the dial, caseback, crown, pushers, and clasp. A video of the chronograph start, stop, and reset is better.
