The fastest check is the running seconds hand in the 9 o'clock subdial. A genuine Moonwatch beats at 21,600 vibrations per hour, so that hand glides. A quartz counterfeit ticks once per second. Two more checks follow: the bezel dot over the 90 and the caseback.

What the genuine watch is
The current Moonwatch is reference 310.30.42.50.01.002 for the hesalite crystal and 310.30.42.50.01.001 for the sapphire crystal. The case is steel, 42 mm across, about 13.2 mm thick on the hesalite model. The movement is the Omega caliber 3861: manual wind, co-axial escapement, 50 hours of power reserve, magnetic resistance to 15,000 gauss, METAS Master Chronometer certification at 0/+5 seconds per day. The dial has three subdials: running seconds at 9, a 30-minute counter at 3, a 12-hour counter at 6.
Identifying Falsified Moonwatch: A Comprehensive Guide
Movement tells
- Quartz copies show a jumping seconds hand and a dead chronograph. Pushers feel soft.
- Mechanical copies use a Chinese ST19 derivative or an Asia 7750. The 30-minute counter may not return to zero when reset.
- The winding action on a 3861 is smooth with a defined stop at full wind. Copies feel gritty or run past the stop.
- A display caseback on a counterfeit shows unfinished bridges, no co-axial wheel, and a rotor on a watch that should be hand wound.
Dial and bezel tells
The 3861 bezel carries a dot directly above the numeral 90. The earlier 1861 bezel has the dot set diagonal to the 90. Many copies mix the two or print the dot in the wrong position. Look at the tachymeter numerals: on a genuine insert the paint sits inside sharp engraved recesses, with no bleed at the edges.
The applied Omega logo is a separate metal piece with flat polished faces. Counterfeits print the logo or use a sticker with rounded edges. The step between the outer dial and the inner track is a machined ledge. Copies mold it as a soft slope.

Hands are polished with beveled edges and the lume fill sits level with the frame. On copies the fill sits proud or shows bubbles.
Case and caseback
The hesalite version has a solid caseback with the seahorse medallion in relief. The engraving is deep, the letters have square shoulders, and the hippocampus detail holds up under a loupe. Copies show shallow stamping and blurred fins. The sapphire version has an exhibition back with a laser etched serial around the rim.
A steel Moonwatch on the bracelet weighs more than 140 g. A counterfeit with a plated brass case is lighter and the plating wears through at the lugs within months.
Box, papers, serial
Omega ships a wooden box, a warranty card, a pictogram card, and a Master Chronometer card. The serial on the caseback, the card, and the movement should match. Counterfeit sets reuse one serial across many sales, so ask for a photo of the engraving and compare digits.
Price and legal risk in the US
Omega lists the Moonwatch above $7,000 USD depending on crystal and strap. Any steel Moonwatch offered near $500 is a copy. Selling counterfeit goods violates 18 U.S.C. § 2320. Import is barred under 19 U.S.C. § 1526, and CBP can seize the shipment with no refund. No counterfeit is 1:1. Every copy differs in at least one measurable dimension: weight, thickness, beat rate, or bezel geometry.
