Short Answer
Omega 2579 shows up in vintage Omega records as a 1950s caliber designation, and it also gets used in the replica trade as a loose label for mid century round case dress watches. Most listings carrying that number are not copying one exact watch. They copy a shape: a 34 to 36 mm steel case, a domed crystal, a clean dial with thin baton or leaf hands, and a stitched leather strap. Before you pay, make the seller state which number they mean and what original piece the copy is based on. A vague answer tells you the listing is a made up tag.
Before You Start
- Ask for front, caseback, crown, and movement photos in one message
- Note the claimed case diameter, lug width, and thickness
- Get the movement type in writing, hand wound or automatic
- Check your local rules on buying and importing replica goods
How to Check a 2579 Style Replica
- Measure the listed case diameter against the original, which sat between 34 and 36 mm. Anything at 40 mm or more is a modern rework, not a vintage copy.
- Look at the lug shape. Mid century Omegas used straight, narrow lugs with a sharp step down from the case top. Soft, thick lugs are a dead giveaway of a cheap casting.
- Ask where the crown sits. On a genuine layout the crown sits at 3 o'clock and stays close to the case. A gap of more than about a millimeter means the case was not cut for that movement.
- Request the movement name and beat rate. Vintage style copies should run at 21,600 or 28,800 vibrations per hour and should hack or not hack exactly as the seller claims.
- Read the caseback text. Engraving should be shallow and even. Deep laser etching with a glossy finish does not match 1950s tooling.
- Compare the dial print. Period fonts are thin, spaced wide, and applied at a slight arc on curved dials. Thick blocky text on a flat dial is a modern print job.
- Check the crystal. A domed acrylic or sapphire with a visible edge is correct. A flat crystal flush with the bezel is not.
- Put the seller's photos next to archive images of the actual reference. If the seller cannot supply photos that match from three angles, walk away.
- Confirm the return window in writing before payment. Two weeks minimum, with return shipping stated.
Price Tiers
Under roughly 150 dollars you get a stamped case, a generic quartz or low grade automatic, and printed dial markers. Between 200 and 500 dollars the case is usually milled, the movement is a known clone caliber, and the dial uses applied markers. Above that you are paying for hand finishing, correct fonts, and a movement that can be serviced. Pay for the tier you can verify, not the tier the listing promises.

Red Flags

- Claimed Swiss movement with no visible balance wheel in the photo
- A price that jumps between listings for the same item
- No stated case dimensions
- Pressure to pay outside a trackable payment method
Legal and Practical Notes
Replica watches are not genuine Omega products and carry no factory warranty or service support. Sales and imports are restricted or banned in many countries, and customs seizures happen. Buy with a payment method that offers dispute rights, keep the listing text and photos, and treat any watch you receive as a fashion item rather than a collectible.
