The replica Speedmaster 1957 6th generation is the sixth revision of a copy built around Omega's 1957 Speedmaster, the reference CK2915, and the anniversary re-edition Omega produced for the model's 60th year. The generation number comes from the replica workshop, not from Omega, so it describes how many times that maker has reworked the case, dial, and movement rather than pointing to an official product line. Treat it as a version tag, not a quality grade.

What "6th generation" means in the replica market

Replica makers release watches in batches, and each batch gets a version label. Some sellers use v2, v3, and so on. Others count in generations. A 6th generation usually means the sixth time the workshop has changed the tooling behind the watch.

Typical changes between generations include a new case mold, corrected dial printing, a reshaped bezel insert, an upgraded crystal, or a different movement supplier. The numbering is not standardized across sellers. One shop's 6th generation may match another shop's version three, so the label alone tells you very little.

The watch being copied

The 1957 Speedmaster, reference CK2915, was the first watch to carry the Speedmaster name. It set the template that collectors still use when they judge a copy.

  • Case diameter in the 38 to 39mm range. The 60th anniversary re-edition measured 38.6mm.
  • Straight lugs with no crown guards, and a slim profile.
  • Broad arrow hands filled with lume.
  • Tachymeter bezel with the dot over 90 marking and the diagonal dot at 70.
  • Hand wound chronograph movement. The original used the calibre 321, and Omega's anniversary re-edition used the calibre 1861.
  • Hesalite crystal rather than sapphire on both the vintage piece and the re-edition.
  • Three subdials at 3, 6, and 9, with running seconds at 9.

What to inspect on a 6th generation copy

Pictures hide a lot. Ask for close shots of the case flank, the dial under bright light, and the case back before you commit.

  • Case: check that the lugs are straight and thin, with bevels that catch light along the top edge. Thick lugs are the quickest giveaway.
  • Dial: confirm the subdial spacing, the kerning of the printed text, and whether the logo is applied or stamped.
  • Hands: the broad arrow should reach close to the minute track without touching it.
  • Bezel: verify the dot over 90 and the diagonal dot at 70. A bezel without them is a different reference dressed up as a 1957.
  • Crystal: hesalite domes and reflects differently from sapphire. Neither is wrong, but the listing should say which one you get.
  • Strap and lugs: the vintage case takes a narrow strap, so confirm the listed lug width matches the strap you plan to use.

Movement options in this tier

Most 6th generation builds use one of three movement families, and the choice drives the price more than any cosmetic detail.

  • ST19 based hand wound: the common option. It gives a mechanical chronograph with a pusher feel close to the original layout.
  • Column wheel copies of the 321 architecture: fewer makers offer this, and it costs more. The visual difference is the column wheel and chronograph bridge finish under a display back.
  • Quartz: the cheapest path. Subdial behavior often differs, and the sweep is wrong for a vintage chronograph.

Ask which subdial is running seconds and which is the 30 minute counter. A swapped layout is a structural flaw you cannot fix later.

Common tells to look for

  • A date window. The 1957 Speedmaster never had one.
  • Subdials pushed too close to the center of the dial.
  • A tachymeter scale with a plain 90 and no dot.
  • Crown guards, which belong to later Speedmaster references.
  • Case back engraving with the wrong reference or missing text.
  • Dial text that sits on a flat surface where it should be raised, or the reverse.

Before you buy

These watches are not made by Omega and carry no manufacturer warranty, service network, or factory parts support. Counterfeit goods are restricted in many countries, and customs can hold or seize a shipment. Resale is difficult, and the watch cannot be presented as a genuine Omega anywhere. If those limits matter to you, an affordable chronograph from a mainstream brand is the safer route.

If you decide to buy anyway, ask the seller what changed between the fifth and sixth generation, request a short video of the chronograph starting, running, and resetting, and confirm the return window in writing before payment.
