Cheap replicas sometimes have the logo glued to the crown. Ascertain that the crown has no indication of glue or rough edges. The watch should also wind smoothly and effortlessly. Some replicas imitate the engraving on the watch crown with laser etching, but this method is rarely used on authentic watches. In addition, some watches have jewels embedded in the crown. On genuine watches this jewel is usually a sapphire or ruby while replicas normally use a glass or crystal stone that can easily be spotted by its dull appearance.The Band: Pins or Screws: Watches generally have leather, rubber, ceramic, carbon fiber, or metal straps or bands, which are straightforward to replace and customize to the owner's needs or taste. Quality leather watch bands are padded or have a soft leather inner section. Metal bands, on the other hand, are harder to duplicate. The cheaper bands are made of low-grade stainless steel and are typically held together with pins instead of the screws that most genuine manufacturers use. The more expensive bands are of higher-quality steel and use screws.
