What does a replica Omega Seamaster 300M 512 cost?
Plan on $280 to $650 for a replica Omega Seamaster 300M sold under the 512 listing code. Under $350 buys a 42mm steel diver with a basic Chinese automatic and a printed dial. Over $500 buys a clone 8800 or a Swiss ETA 2824, a ceramic bezel insert, and a case that lands within a millimeter of the real 13.6mm thickness.

The spread is wide because 512 is not a factory name. It is a listing slot that sellers reuse for different builds, so the same number can hide a $300 watch and a $600 watch.
Is 512 a factory or an Omega reference number?
Neither, in most cases. Omega's own reference for the steel Seamaster Diver 300M is an 11-digit string such as 210.30.42.20.03.001, and no replica factory stamps its output with 512.

Treat 512 as a catalog slot: one seller's batch number, a stock-keeping unit, or shorthand for a bundle of watch, box and spare strap. Ask for the factory name and the movement before you compare two prices.

Three questions that settle the price
- Which factory built it, and which version of that build?
- Which movement sits inside, and is it a clone or a decorated cheap unit?
- What comes in the box: papers, spare rubber strap, caseback tool?
Price tiers and what each one buys
- $280 to $350: 2813-grade automatic, stamped bezel, flat printed dial, shallow caseback engraving. It runs, but the sweep is choppy and the bezel has play.
- $350 to $450: ETA 2824 clone, ceramic insert, sapphire with anti-reflective coating, lume that lasts past midnight. This is the value band.
- $450 to $650: clone 8800 with correct winding feel, laser-cut wave dial, sharp date font, working helium valve crown, solid end links. Closest to the real watch on the wrist.
Past $650 you are paying for a Swiss movement swap or a modified case, not for a better dial. Decide which of those you want before you send money.
Which movement should you pay for?
Clone 8800
Copies the layout of Omega's in-house calibre, with a 25,200 vph beat and twin barrels in the better builds. It adds $150 to $250 to the bill. Parts are not sold loose, so treat it as a wear-and-replace unit.
ETA 2824 clone
Easiest to live with. Parts are common, any watchmaker can regulate it, and the 28,800 vph beat gives a smooth sweep. This is the pick for everyday wear.
2813 and similar budget units
Cheap, loud rotor, short power reserve. It keeps time when new. It does not survive a drop onto tile.
Does the case size match the real Seamaster?
The genuine Seamaster Diver 300M measures 42mm across, 13.6mm thick, with a 20mm lug width. Replicas in the $300 band often run 14.5mm to 15mm thick, which sits high on the wrist and tucks under no cuff.
Ask the seller for a caliper photo of the caseback to crystal. A build that hits 13.6mm to 14mm points to a factory that cared about the case, not just the dial.
What to check before you pay
- Dial: the waves should be laser-cut and show depth at an angle. Printed waves look flat.
- Date: window at 6 o'clock, digits in the right weight. Fat numerals are the giveaway.
- Helium valve: at 10 o'clock, with a crown that unscrews on real thread.
- Bezel: 120 clicks, no back-play, insert flush with the ring.
- Lume: charge it under a lamp for 30 seconds. Faint green after 10 minutes means cheap paint.
- Bracelet: solid end links, screws rather than pins, clasp engraving that lines up.
Common pitfalls in 512 listings
Photos of a $600 watch with a $300 watch in the box. Ask for timestamped shots of the exact unit, crown side and caseback, before you commit.
"Swiss made" on the dial of a $300 listing. A Swiss movement plus ceramic and sapphire does not fit that price, so one of the claims is false.
Water resistance claims. A $400 replica handles rain and handwashing. Do not swim with it unless a watchmaker pressure-tests the seals first.
Frequently asked questions
Is a $500 replica Seamaster worth it?
If you want the closest visual match and plan to wear it often, yes. The $450 to $650 band fixes the details people notice: thickness, dial depth, date font and bezel feel.
Do these replicas keep accurate time?
A 2824 clone regulated at the factory lands within about 15 seconds a day. A 2813 drifts more and loses accuracy as the pivots wear.
Can a watchmaker service it?
Most will work on a 2824 clone because parts are easy to source. Few will touch a clone 8800, since the factory sells no spares.
Before checkout
- Get the factory, version and movement confirmed in writing.
- Ask for photos of the actual unit with a dated note in frame.
- Check the return window and whether shipping is tracked door to door.
- Pay with a method that has a dispute process.
A 512 listing is only as good as the answers behind it. Price tells you the band. The factory and movement tell you the watch.
