Whenever you assemble a "Top 10" list it's always opinionated and ephemeral. Opinionated in that the quality scale and ratings come from from an individual or group with a very subjective view of things. I have things that I consider important points when it comes to determining accuracy of replica watches that someone else might consider trivial for example.

Recently there has been an increased interest in counterfeiting a number of brands that have been immune up until this point. Graham is a perfect example of this trend. Its models and designs don't fit into the typical replica watch categories, but there must have been sufficient interest because two different models (Swordfish and Chronofighter) have been replicated by one of the better replica manufacturers.

The Audemars Piguet Royal Oak has long been a favorite watch to counterfeit. I have seen examples dating back to 2001 for the Royal Oak Offshore. Back then the state of the art was poor stainless steel and quartz movements, easily spotted by even an amateur observer. As with most replica watches the situation improved over time.
