First copy" watches are replicas or imitation watches that are designed to resemble original, branded watches (in this case, Casio). These watches aim to look like the real deal but are sold at a much lower price point. Some key points to keep in mind: Quality: The build quality of first copy watches can vary. They may look similar to the original, but the materials, movements, and durability are often lower quality. Legality: Selling counterfeit or replica watches can sometimes violate copyright or trademark laws. It's important to check the legal standing in your region before buying or selling these watches. Cost: First copy watches are generally much cheaper than authentic Casio watches but might not offer the same level of performance or longevity. If you’re looking for a first copy Casio watch, there are local retailers or online marketplaces (like eBay, AliExpress, or similar) where these are often available. However, if you’re after genuine Casio watches, I’d recommend purchasing from authorized dealers or reputable online stores.
