The best fake Speedmaster Cal 863 is a 42mm manual-wind replica that uses a Lemania-style chronograph movement, most often the Seagull ST19, with sub-dials at 3, 6, and 9 o'clock. If you want the closest match to the original Moonwatch, start with a hand-wound ST19 version and skip quartz or automatic copies that change the dial layout or pusher feel.
Why the Cal 863 matters in a replica Speedmaster
Omega's Caliber 863 is a hand-wound chronograph movement with a rhodium-plated finish, 17 jewels, and a beat rate of 21,600 vibrations per hour. In a replica, you will not get a real Omega movement. What you can get is a movement that copies the same operating style: manual winding, a chronograph start that feels mechanical, and a slim case profile. The ST19 is the common choice because it is hand-wound, reliable when serviced, and fits the 42mm Speedmaster case.

Our pick: ST19 manual-wind fake Speedmaster Cal 863
For most buyers, the best fake Speedmaster Cal 863 is the ST19 version with a 42mm stainless steel case, a tachymeter bezel, and a domed hesalite or sapphire crystal. It offers the correct hand-wound experience, a good power reserve, and a dial that reads correctly from a normal viewing distance. Look for a version with a solid caseback or a display back, depending on the reference you want to copy.

What to check
- Movement: Seagull ST19 or a similar hand-wound chronograph. Avoid quartz.
- Case size: 42mm across, 20mm lug width, and about 13mm thick.
- Sub-dials: 3, 6, and 9 o'clock positions, not a 6-9-12 layout.
- Pushers: two round pushers at 2 and 4 o'clock with a firm click.
- Crystal: hesalite for vintage look, sapphire for scratch resistance.
Other fake Speedmaster Cal 863 options
1. Quartz replica
Quartz Speedmaster replicas are cheap and keep time well, but they fail the main point of a Cal 863 replica. The seconds hand ticks instead of sweeping, the chronograph pushers feel hollow, and the case is often thinner. Only choose this if you want a costume watch and do not care about movement type.

2. Automatic replica
Some replica Speedmasters use an automatic movement with a winding rotor. This can be convenient, but the extra rotor adds thickness and the dial sub-dials often sit at the wrong positions. For a Cal 863 look, a manual-wind movement is the better match.
3. High-end ST19 with sapphire caseback
If you want to show the movement, pick a version with a sapphire display back. The ST19 is not a beautiful movement by Omega standards, but a decorated version with blued screws and a signed bridge can look close enough. This is usually the most expensive replica option, but it also feels the most complete.
What to avoid in a fake Speedmaster Cal 863
- Sub-dials at 6, 9, and 12 o'clock, which do not match the Moonwatch layout.
- A date window at 3 o'clock on a model that should not have a date.
- A case that is larger than 42mm or has thick lugs.
- A movement that is not hand-wound if you want the Cal 863 experience.
- Photos that hide the movement or the caseback.
Final verdict
Pick the ST19 manual-wind fake Speedmaster Cal 863 first. It gives you the right size, the right sub-dial layout, and the right winding ritual. Then compare options based on crystal type, caseback, and finishing. A quartz or automatic replica can work as a casual watch, but it will not deliver the same feel as the original Caliber 863 Speedmaster.
