The Short Answer
The reference 2579 belongs to the first wave of Omega Seamaster models from the early 1950s, and it is a vintage watch, not a current one. That single fact shapes every buying decision. If you want the look and feel of this watch on your wrist, buy an authentic vintage example in honest, serviced condition. The counterfeit versions that surface under this reference are weak imitations: a modern generic case with a stamped logo, a quartz or low-grade automatic inside, and none of the proportions or patina that make the original interesting. Replica makers chase modern references because those are what buyers photograph and compare. A 70-year-old bumper-wind Seamaster is difficult to copy and easy to expose, so the copies tend to be obvious once you know the details.
If you are searching because someone has offered you a watch described as a genuine 2579, treat authentication as the first step, not the last, and never send payment before a movement photo and a case back photo are in your hands.
What to Look For
- Correct reference markings stamped inside the case back, matching the dial layout and the movement family.
- A bumper automatic movement from the period, with a signed rotor and a jewel count consistent with the calibre.
- Case proportions that match the era: modest diameter, thin lugs, and an acrylic crystal.
- Dial printing that reads cleanly under magnification, with even finish and no fuzzy or doubled text.
- Hands that match the dial in style and finish, with lume that ages the same way as the dial plots.
- A seller who will share sharp photos of the movement, the inner case back, and the dial in natural light.
Typical Parameter Bands for This Reference
Use these ranges as sanity checks. Sellers quoting figures far outside them are usually describing a recased or later watch.
- Case diameter: roughly 34 to 36 mm, which was standard for mid-century Seamaster cases.
- Lug width: about 18 mm on most examples of this era.
- Case material: stainless steel most often, with gold-capped variants in circulation.
- Movement: bumper automatic, 17 jewels, from the 340 or 350 series families.
- Crystal: acrylic, domed, replaced often and not a red flag on its own.
- Crown: unsigned or lightly signed depending on production year, so a missing logo proves little.
- Case back: screw back or snap back depending on batch, with markings struck inside rather than printed.
Pitfalls That Cost Real Money
- Redials. Repainted dials lose value fast. Look for soft edges on text, paint over the lume plots, and a gloss that does not match the age of the case.
- Frankenwatches. A genuine case, a period dial, and a movement from a different reference can be assembled into something that passes a glance and fails a service.
- Heavy polishing. Rounded lug edges and washed-out bevels mean metal has been removed and cannot be restored.
- Re-lumed hands or dial. New lume under old paint is a mismatch that collectors spot immediately.
- Stock photos. Listings that reuse the same images across several sellers are a warning sign, especially on marketplace platforms.
- Counterfeit goods and customs. Importing a fake branded watch can lead to seizure and destruction of the item, and no authorized service center will touch it.
- No movement photo. A seller who will not open the case back is asking you to buy blind.
FAQ
Is there such a thing as an accurate replica of the 2579?
Not in the way there are close copies of modern sports models. The value of this reference sits in a bumper movement, vintage case geometry, and decades of patina. Copies miss all three, so most examples sold as replicas are generic watches wearing a familiar name.
How do I confirm the reference number?
Ask for a clear photo of the inside of the case back, then compare the stamping with the dial, the crown position, and the movement. The reference should be consistent across all of them. A watchmaker can verify the movement family in minutes.
Should I buy one for daily wear?
A vintage Seamaster can be worn regularly, but budget for a service and accept that water resistance on a watch this old is gone unless it has been rebuilt. If you want a worry-free daily watch, a modern reference is the better tool.
What paperwork matters?
Service receipts and a written description from the seller carry more weight than an old box. Photographs of the movement before and after a service tell you what was replaced.
What if the watch turns out to be fake after I buy it?
Stop wearing it, keep every message and payment record, and pursue a refund through the platform or your payment provider. Document the discrepancy with photos from a qualified watchmaker.
