I'll be blunt: "Omega 2791 replica" is a search term, not a product. The number 2791 shows up in two places, a vintage Omega reference from the early 1950s and a movement designation some sellers borrow, and plenty of listings just bolt it onto a modern Seamaster or Speedmaster rep that has nothing to do with either. Before you compare factories or prices, pin down which watch is actually in the photos.
How to tell which watch you're being shown
Ask the seller for the case diameter, lug width, and a photo of the caseback and movement. A serious seller answers within a day. The answers settle the question fast.
- Case size. Early 1950s Omega cases sat around 34 to 35mm with 18mm lugs. A "2791" listed at 41mm is a modern rep wearing a vintage name.
- Seconds hand. Vintage references of that era are typically small seconds or center seconds with a slim hand. A big chunk of luminous arrow is a modern design cue.
- Caseback. Vintage Seamaster pieces carry a hippocampus medallion and a reference number engraved inside. Modern replicas often have a display back, which no 1950s watch had.
- Movement. The automatics of that period were bumpers. They wind with a soft thud and no rotor spin. If the seller describes a smooth spinning rotor, you are looking at a modern clone movement in a vintage styled case.
What I inspect in the photos
- Dial printing at 12 o'clock, shot close. Look for sharp serifs on the logo and even spacing in the text below it. Soft or merged letters are the most common tell.
- Applied markers and hands. They should sit level and catch light the same way. Painted lume that looks chalky under a macro shot usually means a cheap dial.
- Patina. On a vintage styled rep, aged lume should match between dial and hands. Uneven or orange painted plots read as fake at arm's length.
- Crown. Signed, correct diameter, and sitting flush with the case band.
- Case finishing. Look at the lug tops under direct light. Rounded, over-polished edges on a supposed 1950s watch are a giveaway, since the original geometry is crisp.
Red flags that repeat
- Stock catalog renders instead of photos of the actual unit.
- "1:1 Swiss made" language with no movement photo.
- No stated case size, or a size that contradicts the reference.
- No return window. On a watch you cannot handle first, that matters more than the price.
- A price far under the market for the movement described. Something got swapped.
What a decent one costs
Modern replica Omegas with a clone automatic movement generally land in the low hundreds of dollars, and the finishing tracks the price closely. Vintage styled reps are cheaper and cruder, and the gap shows up in dial printing and case softening rather than in the movement. If a listing promises vintage correctness at a bargain price, expect to compromise on the dial.

Living with it
Treat water resistance as decorative unless the seller states it was tested. Have any automatic replica checked by a watchmaker after a year, since factory lubrication varies. And decide up front whether you want a modern watch or a vintage look, because the two searches lead to different sellers, different prices, and very different quality checks.
