Short answer
A replica Speedmaster is a copy of the Omega Speedmaster Professional. Most copies use a 42 mm steel case, a 20 mm lug width, and a tachymeter bezel. The genuine Moonwatch runs the Omega caliber 1861 or 3861. Copies run quartz, a Seagull ST19 manual wind, or a modified automatic movement. Prices for copies range from about $30 to $600. US law bars import and sale of counterfeit goods.
Genuine Speedmaster specifications
The Speedmaster Professional Moonwatch measures 42 mm across, 13.2 mm thick, and 47.2 mm from lug to lug. Lug width is 20 mm. Water resistance is 50 m. NASA flight qualified the Speedmaster in 1965. Omega moved the Moonwatch to the caliber 3861 in 2021. That movement runs at 21,600 vph with a 50 hour power reserve and holds METAS Master Chronometer certification. The prior caliber 1861 had a 48 hour reserve. US retail for a steel hesalite Moonwatch sits near $7,000 to $8,500. Prices change with the market.
What replicas get right and wrong
Good copies match the case diameter, lug width, and dial layout. The dial has three subdials: running seconds at 9 o'clock, a 30 minute counter at 3 o'clock, and a 12 hour counter at 6 o'clock. Common errors include wrong subdial spacing, a date window at 3 o'clock (the Moonwatch has no date), short chronograph hands, a bezel font that sits too thick, and case thickness above 14 mm.
Movement types in replica Speedmasters
- Quartz: about $30 to $80. The chronograph second hand steps once per second. Battery powered.
- Seagull ST19: a Chinese manual wind column wheel chronograph. 21,600 vph, about 40 hours of reserve, 12 hour counter. Bare movements sell for $80 to $180.
- Automatic 7750 copies: 28,800 vph, thicker cases at 14 mm to 16 mm, and more weight on the wrist.
Price bands
Budget copies land at $30 to $100. Mid tier copies run $100 to $250. High tier copies run $300 to $600. A used genuine Speedmaster 3570.50 trades near $4,000 to $6,000. Movement grade and case finish account for most of the gap.
Legal status in the United States
18 U.S.C. § 2320 makes trafficking in counterfeit goods a federal crime. Penalties reach 10 years in prison for a first offense and 20 years for repeat offenses. Civil claims under 15 U.S.C. § 1117 allow statutory damages of $1,000 to $200,000 per counterfeit mark, and up to $2,000,000 for willful use. US Customs and Border Protection seizes counterfeit shipments at ports of entry and destroys them. Selling a replica as a genuine Omega is fraud.
Homage watches
An homage copies the shape and dial layout without the Omega name or the Ω symbol. Homage watches are legal in the US. The trademark, not the case design, creates the counterfeit claim in most cases.
