How to spot a fake Omega Seamaster?
As one of the popular collections today, the Omega Seamaster series has numerous replica versions on the market that make it difficult for many to distinguish between genuine and counterfeit pieces. So, how should one tell whether an Omega Seamaster replica is genuine or fake? Below, we share methods for authenticating Omega Seamaster watches for your reference.
Methods for authenticating Omega Seamaster watches
1. Check the serial number on the case back.
Almost all Omega watches have a serial number, which is unique to each individual watch. It is usually engraved on the case back or on the back of one of the lugs, consisting of a 8-digit number. For mechanical watches, this 8-digit serial number also appears on the edge of the movement plate, and the serial number on the case matches that of the movement. On a genuine watch, the serial number is deeply and clearly engraved; if it is on the case back, it will follow the curvature of the back, meaning the digits are arranged in an arc, whereas on replica watches, they are usually arranged in a straight horizontal line.
The serial numbers on currently produced Omega watches are engraved on the back of one of the case lugs. The digits are engraved very small and closely together, a technique that replica watches cannot yet replicate. Replica watches generally feature the same serial number across the board, regardless of whether it is a men's or women's watch or what model it is.
2. Check the hallmarks on the case.
Especially for gold watches, there are many hallmarks on the case, such as the scales symbol, the 18K or 750 mark, the St. Bernard dog head, or the 'Helvetia' woman's head mark. These marks are stamped very small and clearly, while those on replica watches are often coarse and blurred.
3. Check the hallmarks on the bracelet.
On metal bracelets, markings are also engraved on the clasp, which must include a bracelet reference number. Replica markings are generally larger, shallower, and coarser, as this area is difficult to execute properly, often causing replicas to give themselves away. For solid gold watches, the bracelet buckle must also be solid gold and engraved with the corresponding gold hallmarks; missing hallmarks indicate gold plating. Recently, issues have been discovered with leather-strapped Omega watches in this regard, indicating that at least the strap is not original.
4. Examine the watch hands.
The Achilles' heel of replica watches lies in the hands; although small, they are difficult to replicate accurately. The hands of a genuine Omega feature an electroplated surface that is extremely glossy and smooth, with regular and slender shapes (especially the seconds hand), and the luminous material on the hands matches the colour of the dial. Making a comparison reveals the differences without difficulty.
5. Examine the dial.
The characters and lacquer prints on the dial should also be very neat and have a glossy surface. If the hour markers are set with gemstones, they should primarily be natural diamonds, whereas replica watches typically use rhinestones and make them larger than those on genuine watches. The lacquer prints on the dial, including letters and minute tracks, should be very clear and lustrous, whereas replica prints tend to look dull and blurred. The SWISS MADE lettering should be located at the very bottom of the dial near 6 o'clock, closely hugging the crystal's inner tension ring, whereas replica watches usually print this line of text somewhat higher up.
6. Examine the watch guarantee card.
Omega watches usually come with 2 to 4 guarantee cards (depending on the specific watch model), which are dark red and the size of a credit card. They are printed with the watch numbers (model number, serial number, movement number, and stamped with the dealer's blue stamp), corresponding one-to-one with the watch. The contents of the guarantee card include: International Warranty, Chronometer Certificate, Precious Stones Certificate, and Pictograms. Fake watches often have mismatched numbers, mismatched functions, or lack the dealer's blue stamp.
