Short answer
There is no official synonym for 'fake Speedmaster Cal 861.' The phrase is seller shorthand. It joins three terms: fake or replica, Speedmaster, and Caliber 861. Listings use variants like '861 replica,' 'Cal. 861 copy,' 'Speedmaster 861 fake,' and 'Lemania 1873 clone.' These labels point to a copy of a Speedmaster that uses a movement in the Caliber 861 family, or a movement sold as a clone of it. The labels do not certify the movement inside.

What Caliber 861 is
Caliber 861 is an Omega manual-wind chronograph movement. Omega introduced it in 1968 as the replacement for Caliber 321. It powered Speedmaster Professional references until 1997, when Caliber 1861 took over. The 861 is a cam-controlled design. It shares architecture with the Lemania 1873. That link explains why some listings use 'Lemania 1873' as a synonym for the base movement.
Fake Speedmaster Cal. 861: How to Tell a Real Movement From a Copy
Synonyms you will see
- Cal. 861 replica: A copy sold with a movement described as Caliber 861. The description may refer to a clone, a modified donor, or a genuine movement. The listing text does not prove which one.
- Speedmaster 861 fake: A copy made to pass as an Omega. The term 'fake' signals intent to deceive. A seller may use it for search traffic.
- Moonwatch 861 copy: 'Moonwatch' is a nickname for Speedmaster Professional models. It is not a synonym for Caliber 861. Moonwatch models have used Caliber 321, 861, 1861, and 3861.
- Lemania 1873 clone: A movement built to the Lemania 1873 pattern. The Omega 861 is related to that pattern. A clone is not an Omega movement.
- Pre-moon 861 replica: A copy of a pre-1969 style case with an 861 description. The label mixes case era and movement type. Check the reference, not the label.
What the synonyms do not tell you
A listing term does not confirm the movement, case, dial, or serial number. A copy may use a generic manual-wind chronograph, a quartz movement, or a decorated plate. A Speedmaster with Caliber 861 has a known layout: chronograph pushers, a crown at 3 o'clock, and three subdials. Photos can show the layout. Photos cannot prove the parts are Omega. A genuine 861 movement has Omega markings and a known finish. A clone can copy the markings. A watchmaker can check the movement.
Fake, replica, copy, homage
'Fake' and 'replica' are not legal synonyms. A fake is a copy made to pass as genuine. A replica is a copy sold as a copy. A copy is a neutral word. A homage is a watch that borrows design cues and carries a different brand name. Listings mix these terms. The word 'homage' does not make a watch with an Omega logo legal.

Risk and legal note
Counterfeit goods can violate trademark law in the US. US Customs and Border Protection can seize counterfeit goods. Sale and import can carry legal risk. A listing that uses 'Cal. 861 synonym' in the title may be a search tactic, not a statement of origin. Ask for movement photos, service records, and a return policy. If the seller cannot name the movement maker, treat the listing as unknown.
