Most pawn shops do not have the expertise or resources to fully authenticate watches, particularly high-end luxury watches. However, some pawn shops may have a general knowledge of watches and may be able to identify certain brands or models. 

If you are considering buying or selling a luxury watch, it's always best to have it authenticated by a professional watch appraiser or a reputable watch dealer. They will have the knowledge and expertise to identify the authenticity of the watch, including its movement, materials, and overall condition. 

Additionally, some luxury watch brands have authorized dealers and service centers that can provide authentication and certification services. It's important to do your research and work with reputable and knowledgeable professionals to ensure that you are buying or selling an authentic watch.
