Pick first: A2824 De Ville 424.10.40 on steel
The first pick is a 39.5 mm steel De Ville replica with an A2824 automatic and a screw-down caseback. The A2824 is a known movement. Parts are cheap. Most watchmakers can regulate it. Beat rate is 28,800 vph, so the seconds hand sweeps 8 times per second. The genuine calibre 2500 runs at 25,200 vph. Case thickness on the better builds lands near 10.5 mm. Listings in this tier run $200 to $450. Ask the seller for the case diameter and the movement name in writing before you pay.
Dial details on this tier: applied Roman numerals or baton markers depending on the reference copied, printed "De Ville" under 12, date at 3. Check three things in photos. The gap between the Omega wordmark and the Greek symbol. The bevel on the date window. The serif shape on the numerals I and V.

Option 2: Miyota 9015 build
The Miyota 9015 measures 3.9 mm thick and runs at 28,800 vph with a 42 h power reserve. That height helps the case profile on a slim dress watch. Trade-offs: the rotor is louder, the date change has a small jump, and the crown feels lighter than the genuine. Sellers who name the movement in the listing are easier to deal with than sellers who write "imported automatic".
Option 3: Quartz and gold-plated versions
Quartz De Ville replicas cost $60 to $150 and measure about 8 mm thick. The ticking seconds hand is a clear tell against a 25,200 vph sweep. Gold-plated versions use 3 to 5 microns of plating on a brass or steel case. Plating wears through at the clasp edge in months of daily use. Skip both if the watch will sit next to a genuine one.

Genuine specs to compare against
- Reference 424.10.40.20.02.001: steel case, 39.5 mm diameter, 20 mm lug width.
- Calibre 2500: automatic, co-axial escapement, 27 jewels, 25,200 vph, 48 h power reserve.
- Crystal: domed sapphire, anti-reflective coating on both faces.
- Water resistance: 30 m.
- Bracelet: steel, folding clasp, push pins.
- Service: Omega guidance runs 5 to 8 years. Parts come from Omega.
Where the tiers differ
- Movement. The 2500 uses a co-axial escapement and a free-sprung balance. Replicas do not copy it. Decorative plates are cosmetic only in appearance, not in function.
- Case finishing. The genuine has sharp transitions between brushed and polished facets. Replicas round those edges.
- Dial. Print weight, applied marker height, date wheel font.
- Bracelet. End link fit at the lugs and clasp engraving depth.
- Water resistance. A replica marked 30 m has no test certificate. Keep it dry.
Checklist before you pay
- Ask for the case diameter in mm and a caliper photo.
- Ask for the movement name and a photo of the rotor.
- Confirm the date font in a close-up. The 1 and the 7 are the common mismatch.
- Check end link fit at the lugs in a side photo.
- Confirm the return window in days.
Bottom line
The A2824 steel build is the pick. It keeps the 39.5 mm case, the automatic sweep, and a serviceable movement at $200 to $450. The Miyota 9015 build is second if case thickness matters more than rotor noise. Quartz and plated versions are cheapest and the easiest to spot. A replica is not a genuine watch: no factory warranty, no service history, no resale value. Compare it to the real 424.10.40 with that in mind.
