Speedmaster Professional: real vs fake
The Speedmaster Professional is the classic hand-wound chronograph, and replicas most often give themselves away on dial printing and the tachymeter font on the bezel. A genuine dial has three perfectly aligned subdials, with razor-sharp "PROFESSIONAL" text and a crisply applied Omega logo. Shoot the dial, bezel and hands and run them through LegitCheck AI to catch discrepancies in minutes.
What to check on the Speedmaster Professional
Model-specific zones — on top of the brand-level signs.
Dial printing & logo
The "OMEGA", "Speedmaster" and "PROFESSIONAL" text is printed razor-sharp with no blurred edges or bleed. The applied metal logo sits perfectly straight. Replicas often use painted text that smears or sits off-center.
Three subdials and their alignment
A Speedmaster has exactly three registers (running seconds, 30-minute and 12-hour counters). At rest the counter hands point dead-straight to 12 on their own axes, the rings are concentric and the graduations even. Tilted or misaligned hands are a red flag.
Tachymeter bezel scale
The "TACHYMÈTRE" scale and its numerals use the correct Omega font, the graduations are even, and "60" sits at 12 o’clock (with the high 400–500 numerals just past it). Fakes use a font of the wrong weight, crooked numerals or wrong positioning.
Hands & lume plots
Hands are straight and burr-free, and the lume on the markers and hands is applied evenly in a single consistent tone. Patchy, uneven or mismatched-color lume fill is typical of replicas.
Crown & pushers
The hand-wind crown and two chronograph pushers have crisp knurling and a springy but precise action; a genuine crown carries the Omega symbol. Play, mushy pushers or a plain crown betray a copy.

FAQ
How many subdials does a real Speedmaster Professional have?
Exactly three: running seconds plus 30-minute and 12-hour chronograph counters. A dial with two registers, or one with an asymmetric layout, is almost always a fake or a different model.
Is the Speedmaster Professional self-winding?
The classic Moonwatch Professional is a hand-wound mechanical chronograph, not an automatic. An automatic rotor on a reference sold as a hand-wind Professional is a reason to be suspicious.
How do I quickly verify a Speedmaster from photos?
Photograph the dial up close, the tachymeter bezel, the hands and the crown, then upload to LegitCheck AI — it compares the printing, fonts and subdial geometry against genuine traits.
