If you searched for a Speedmaster 1957 “4th generation” replica review, the useful answer is this: the top pick for anyone chasing the 1957 look is the Omega Speedmaster 1957 Trilogy re-edition, because it is the one watch that carries the original broad-arrow dial, straight lugs, and unprotected crown in a modern, serviceable case. I compared the realistic routes to that look, the 2017 Trilogy re-edition, an original CK2915, the current production Speedmaster '57, and unbranded homages, against four criteria: case proportions, dial fidelity, movement serviceability, and legal and resale risk. Counterfeit copies were not reviewed, and the next section explains why that is a buying decision, not a snobbery one.

Why the “fourth generation” label is a warning sign
Version numbering (“v1, v2, 4th gen”) is a convention of the copy trade, not of Omega. It exists to convince a buyer that earlier flaws have been fixed, which is a useful sales story and a poor quality standard, since each “generation” is an unlicensed product with no parts chain and no service path. Importing and selling counterfeit watches also carries real exposure in the US: trademark counterfeiting is illegal, and Customs and Border Protection seizes shipments at ports of entry. A comparison guide that ranks fakes by generation would function as a shopping list for infringing goods, so the options below are the legitimate paths to the same wrist presence.
Option 1: Omega Speedmaster 1957 Trilogy re-edition (2017)
The 60th-anniversary Trilogy set reissued the original Speedmaster as a small, broad-arrow chronograph, and it remains the closest thing to a factory-sanctioned time machine.
- Pros: Faithful 1957 proportions on a smaller case; correct broad-arrow hands, lollipop seconds, and steel tachymeter bezel; factory service and genuine parts availability; holds value as a limited anniversary piece.
- Cons: Limited supply and rising secondary prices; the hand-wound movement is a period-correct compromise rather than a modern co-axial; the set was originally sold as a trio, so single-watch examples need paperwork checks.
Use case: Buy this if you want the 1957 look, a clear conscience, and a watch your local watchmaker can actually service.
Option 2: An original 1957 CK2915
The first Speedmaster is the reference every re-edition chases, and it is a collector object rather than a daily wearer.
- Pros: Genuine historical importance; unmatched dial and case finishing from the original run; strong long-term demand.
- Cons: Six-figure territory for clean examples; relumed dials, replaced bezels, and assembled “franken” watches are common; the calibre 321 needs a specialist, and parts are scarce.
Use case: Only for buyers with an expert Authenticator on speed dial and a budget that treats a service as a rounding error.
Option 3: The current Speedmaster '57
Omega's modern '57 line borrows the 1957 dial language and drops it into a contemporary case with a co-axial Master Chronometer movement.
- Pros: Available new with a warranty; magnetic resistance and modern accuracy; broader choice of dials and bracelets; wearable case size for most wrists.
- Cons: Noticeably thicker and larger than the 1957 original; the design is an homage by Omega itself, so purists will point out what changed; depreciation from new.
Use case: The pick for someone who wants the look, wears the watch hard, and prefers a warranty over a provenance story.
Option 4: Legitimate homages
Several small brands sell chronographs with their own name on the dial, off-the-shelf movements such as the Seagull ST19, and a broad-arrow-inspired layout.
- Pros: Low entry cost; your own branding, so no legal exposure; easy to service or replace; good way to test whether the style suits you.
- Cons: Case finishing and dial printing sit a tier below; resale is close to zero; the design is derivative by definition.
Use case: A sensible first step before committing to a Trilogy or a '57.
How to spot a counterfeit 1957 Speedmaster
- Check the crown guards. The 1957 case has none, and copies often add a small lip.
- Read the bezel font under magnification. Base-metal bezels with soft, filled engraving are a common tell.
- Ask for movement photos. A genuine hand-wound Speedmaster shows finished bridges and correct engraving.
- Verify the reference and serial against Omega's archive extract, and insist on original boxes and papers.
- Meet the seller at an authorized dealer or a watchmaker for an inspection before money changes hands.
Bottom line
The 2017 Trilogy re-edition wins on every criterion that matters after the honeymoon: proportions, dial accuracy, serviceability, and resale. A modern '57 is the practical alternative for daily wear, an original CK2915 is a collector purchase, and a branded homage is the low-risk way to try the style. Skip the generation-numbered copies entirely. They cannot be serviced by Omega, they carry legal risk at the border, and the money is better spent on a watch with a real reference number.
