I used to be into watches, viewed and perused fakes and live in China where you can source them from. Basically, I think everyone who really knows watches knows that replicas exist that you really can’t distinguish from real ones unless you really know what you’re looking for and have it in your hand. Yours might suffer from general build quality handiness though and might not be first class replica. Like the other commenter said, the scratches give it away, for example. Even good replicas can include real sapphire glass, I think.

Apart from that , 95% of folks would probably think it’s real, just due to not thinking about it.
