Answer first
A replica Omega 2576 is a copy of a late 1940s Omega case. The number 2576 is a case reference, not a model name. It sits in the same block as reference 2577, the 1948 Seamaster case. Replica factories sell these as vintage Seamaster style pieces with steel cases near 34 mm to 35 mm, domed crystals, and hand wound or automatic movements. Asking prices run from about $110 to $350. No replica uses the original Omega movement. Treat every listing as a lookalike, not a restoration part.
What the number 2576 means
Omega used four digit numbers for cases and for calibers. Vintage reference lists place 2576 in the 1948 to 1952 window, close to the first Seamaster cases. Buyers searching this number find two groups of results: vintage Seamaster case listings and caliber tables. The two groups do not describe the same object. Ask the seller which one they mean before you order.
What sellers ship under this name
- Case: polished steel, 34 mm to 35 mm across, 18 mm lugs.
- Crystal: acrylic dome, sometimes sapphire on newer builds.
- Dial: cream, silver, or two tone, printed logo, applied or painted indexes.
- Hands: leaf or dauphine shape, no lume on most builds.
- Strap: leather, 18 mm, tang buckle.
- Water resistance: most builds claim 3 ATM to 5 ATM. Do not swim with them.
Specs to confirm before payment
- Case diameter and thickness in millimeters, not by photo.
- Lug width, measured with calipers.
- Movement brand and model number.
- Crystal material and height above the bezel.
- Dial print method, pad printed or applied.
- Case back engraving and reference stamp.
Movement choices
Three movements cover most listings. The Miyota 8215 or 9015 is an automatic from Japan and is easy to service. The Seagull ST21 and ST36 are Chinese copies of Swiss designs, hand wound or automatic. The ETA 2824 clone, sold as a 2824 or PT5000, beats at 28,800 vph and costs more. A hand wound ST36 suits a vintage case. An automatic adds rotor thickness, which changes how the watch sits on the wrist.
Case, crystal, and dial checks
Ask for photos of the lugs from the side. Vintage style cases are thin. Many replicas add 1 mm to 2 mm of thickness, and the profile looks wrong. Check the crown size and the crown position. Check that the dial text sits inside the chapter ring and not over it. On a domed acrylic crystal, look for distortion at the edges and a clean seal at the case.
Price bands
Under $120 buys a quartz or a low grade automatic with a plated case. From $120 to $250 buys a steel case, a Miyota or ST movement, and a sapphire or acrylic crystal. From $250 to $350 buys a better dial, a 2824 clone, and closer case finishing. Above $400, the price gap to a real vintage Omega narrows.
What is not known
Factories do not publish production data, serial numbers, or case drawing tolerances. Photos on seller pages are retouched. Weight in grams and case thickness are absent from most listings. Demand measured numbers in writing. If a seller refuses, buy from another seller.
