For most buyers looking at an Omega Speedmaster Moonwatch Master Chronometer clone watch, the top pick is a manual-wind chronograph built on a Seagull ST19 movement, set in a 42 mm case with a domed hesalite-style crystal and a stepped dial with three subdials. It copies the feel of the Moonwatch better than any quartz or automatic alternative at a first copy price. The picks below are ranked on four criteria: how the chronograph actually functions, how the case and crystal look on the wrist, how the dial reads in daylight, and whether the watch can be described for what it is without misleading anyone.

What Master Chronometer means on a clone
Master Chronometer is a certification Omega uses for watches tested by METAS, the Swiss Federal Institute of Metrology. The testing covers rate precision, resistance to magnetic fields up to 15,000 gauss, and performance after magnetic exposure. A first copy watch does not enter that process, so "Master Chronometer clone" describes styling, not measurement. No clone carries a valid METAS certificate, and a seller who claims one is describing something that does not exist. Use the phrase as a design reference and judge the watch on the parts in front of you.
Criteria used for this comparison
- Movement type. Manual wind, quartz, or automatic, and whether the chronograph pushers reset cleanly to zero.
- Case and crystal. Case diameter near 42 mm, lug shape, and whether the crystal is domed acrylic style or flat sapphire style.
- Dial layout. Subdial position and spacing, tachymeter bezel insert, and the shape of the hour and minute hands.
- Honesty of description. Whether the listing states plainly that the watch is a first copy and not an Omega product.
Pick 1: Seagull ST19 manual-wind chronograph
The ST19 is a Chinese-made column-wheel chronograph movement derived from an older Swiss design. It winds by hand, has a smooth pusher feel, and gives the sweeping chronograph seconds hand that the real watch has. This is the closest mechanical match to the Moonwatch experience.

- Pros: Real mechanical chronograph, hand winding matches the original layout, thin enough for a Moonwatch profile, repairable by many watchmakers.
- Cons: Not chronometer rated, service intervals are shorter than a Swiss movement, subdial spacing can sit slightly off on cheaper cases.
Best for: buyers who want the winding ritual and mechanical chronograph action, and who accept that accuracy will vary from watch to watch.

Pick 2: Quartz Moonwatch-style first copy
A quartz version keeps the Moonwatch silhouette at the lowest cost and needs almost no upkeep. The chronograph usually runs on a small stepping motor, so the seconds hand ticks rather than sweeps.
- Pros: Low price, accurate timekeeping, no winding, thin case, easy battery replacement.
- Cons: Ticking seconds hand gives it away to anyone who knows the watch, pusher feel is light, resale value is close to zero.
Best for: a first buy, a gift, or a daily beater where cost and low maintenance matter more than mechanical feel.
Pick 3: Automatic chronograph clone on a 7750 pattern
Automatic chronographs in this style are thicker than the original because the rotor and module stack adds height. They offer self-winding convenience and a sweeping hand.
- Pros: No winding, sweeping chronograph hand, widely available in steel and two-tone finishes.
- Cons: Noticeably thicker case, rotor noise, subdial positions often drift from the true Moonwatch layout.
Best for: buyers who wear a watch daily and dislike hand winding, and who do not mind a taller case on the wrist.
Case, crystal, and dial details that decide the look
A stepped dial with recessed subdials reads closer to the original than a flat printed dial. The bezel should carry a tachymeter scale with a dot over ninety, and the crystal should be domed if you want the classic profile. Check the lug width, since a 20 mm strap is what most Moonwatch-style cases accept. Ask for photos in daylight, not studio light, because reflections hide dial flaws.
Legal and authenticity notes for US buyers
Omega and Speedmaster are registered trademarks. Selling a watch with those marks as genuine is counterfeiting and carries civil and criminal exposure in the United States. A first copy watch should be sold and described as a first copy, with no Omega branding presented as authentic. Anyone promising a METAS certificate with a clone is selling a story, not a watch.
Which one fits you
Choose the ST19 manual wind if you want the closest mechanical match and will service it. Choose quartz if you want the look with no maintenance. Choose the automatic if you wear one watch daily and want it to keep running on the wrist. In every case, buy from a seller who states the watch is a first copy and shows real photos of the actual piece.
