Short answer
A Speedmaster 329 replica is a copy of Omega's 42 mm manual-wind chronograph, so the details that matter are the case shape, the tachymeter bezel, the three-subdial dial layout, and the pusher feel. Copies range from cheap quartz versions with fake subdials to stepped-case builds with a working chronograph movement. Judge the watch on the parts you can see and the functions you can test, not on the seller's photos.
What the 329 layout should show
The case should measure about 42 mm across, with lyre lugs and a bezel that carries a printed tachymeter scale. The dial should hold three subdials at 3, 6, and 9 o'clock, a running seconds hand, and a 30-minute and 12-hour totalizer pair. Pushers sit at 2 and 4 o'clock, and the crown sits at 3. On a correct copy the subdials sit close to the center, and the hour markers are applied, not painted.
Step-by-step check before you pay
- Measure the case with calipers or ask the seller for width, lug-to-lug, and thickness numbers, then compare them to the published reference specs.
- Inspect the bezel insert: the tachymeter numerals should be sharp, evenly spaced, and aligned so the 60 mark sits at 12 o'clock.
- Look at the dial under a light: check that the logo print is crisp, the markers are applied, and no dust sits under the crystal.
- Confirm the subdials work. Ask for a video of the chronograph start, stop, and reset, and watch the 30-minute counter move.
- Time the running seconds subdial for 60 seconds against your phone to confirm it is a real seconds hand and not a painted disc.
- Press the pushers. A working chronograph gives a firm click on start and a clean snap on reset; a quartz copy feels soft.
- Check the bracelet or strap: end links should meet the lugs with no gap, and the clasp should close with a firm click.
- Ask the seller for the movement type in writing, plus water-resistance claims and any service history, before you send money.
Red flags
- Photos that hide the subdials or the caseback
- Listings that call a quartz copy a manual-wind watch
- Prices far below the normal range for a working chronograph copy
- No video of the chronograph running
- A seller who will not confirm the movement type
Match the copy to your budget
A low-cost quartz copy is fine if you want the look and will not use the chronograph. If you plan to wear the watch often, pay more for a copy with a running chronograph movement, a stepped case, and a bezel that lines up. Ask what happens if the watch arrives with a dead subdial, and get that answer in writing before you order.
