The short answer
A cloned Speedster 1957 5th gen is worth your money only when three numbers line up: a case diameter near 38.6 mm, a lug width of exactly 19 mm, and a dial with correct 3-6-9 subdial spacing. Everything else on the watch is decoration. If the seller cannot confirm those three figures, or if the photos show a 20 mm lug gap or a date window that should not exist, move on to another listing. The 5th gen tag describes the newest revision of the case profile, bezel printing, and handset finish. It does not describe a new movement family, so the real gains sit in details you can see in a close photo, not in a spec sheet.
What the 5th gen label actually changes
Replica makers revise in waves. Each wave fixes complaints from the previous one. On the 5th gen run of the 1957 layout, the usual changes are a thinner mid case, a sharper step between the bezel and the case flank, cleaner tachymeter font, and a handset with a flatter profile on the broad arrow hour hand. Some runs also move to a better acrylic crystal with a warmer dome. Ask the seller which batch they hold and request a straight-on photo plus a 45 degree photo. The straight shot shows dial alignment. The angled shot shows case curvature and how the crystal sits above the bezel. A 4th gen with a good dial often beats a 5th gen with a crooked one, so judge the individual watch, not the version number.
Top Pick: FakeSpeedster 1957 5th Gen Replica Watch
What to look for in photos
- Dial spacing: the three subdials should sit close to the center pinion with a narrow gap. Wide spacing signals a movement that does not match the original layout.
- Bezel: the numeral 90 needs a dot above it, not beside it. Lettering should be crisp under magnification, with even spacing across the scale.
- Hands: the hour hand should be wide and flat, the minute hand long enough to reach the minute track, and the chronograph seconds hand should rest exactly at twelve.
- Case profile: straight lugs with a defined bevel, no crown guards, and pushers that sit flush with the case band.
- Caseback: engraving should have depth. Laser-etched outlines look shallow and wash out at an angle.
- Lume: the plots on the dial and the hands should match in tone under the same light.

Mimic Speedster 1957 5th Gen: What to Check Before Buying
- Case diameter: 38.4 to 39.0 mm
- Case thickness: 13.0 to 14.5 mm
- Lug width: 19 mm, no exceptions
- Lug to lug: 46 to 48 mm
- Weight with bracelet: 90 to 130 g
- Beat rate on a manual chronograph: 21,600 vph on the common clone, 18,000 vph on vintage-style builds
- Power reserve: 40 to 48 hours when fully wound
- Chronograph reset: the seconds hand must snap back to twelve in one motion
Movement behavior matters more than movement name
Most clones in this shape run a hand-wound column wheel or cam chronograph. Wind it twenty turns and listen. A clean movement sounds dry and even. Grinding or a gritty feel through the crown points to poor lubrication or a bent stem. Start the chronograph, let it run five minutes, then stop and reset. The hand should return to zero without overshooting. Check that the pushers need firm, short travel rather than a long mushy push. A manual chronograph should never show a rotor when you look through the caseback.
Pitfalls to avoid
- Date windows on a layout that never had one.
- Twenty millimeter lugs paired with a nineteen millimeter case, which forces a squeezed spring bar.
- Sapphire sold as acrylic or acrylic sold as sapphire. Ask which one, then match it against the model you want.
- Hollow bracelet links that make the watch feel light and rattle on the wrist.
- Stock photos reused across several listings from different sellers.
- No return window and no photo of the actual unit you will receive.
Also confirm the rules in your own country before you order. Customs treatment of replica watches varies, and a seized parcel is a total loss.
FAQ
Is the 5th gen always better than the 4th gen?
No. The version number tracks a batch, not a guarantee. Compare the specific watch: dial alignment, bezel font, hand finish, and case bevel. A clean 4th gen beats a sloppy 5th gen every time.
Which single spec should I check first?
Subdial spacing. It is driven by the movement and cannot be fixed with a dial swap. If the spacing is wide, the rest of the build rarely recovers.
Should I pick acrylic or sapphire?
Pick the material that matches the reference you are copying. The classic 1957 shape used a domed acrylic crystal, so that choice keeps the silhouette closer to the outline most buyers want.
What do I inspect on arrival?
Measure the lug width with calipers, run the chronograph for ten minutes, check the reset, wind it fully and time the power reserve overnight, and look for lume matching under a lamp. Report any fault inside the return window.
