Welcome to the forum Harry. You definitely came to the right place to learn about reps. In fact, many of the members here are MUCH better informed on Gen watches than the average gen owner. You have to know what the real thing is like to be able to judge a replica.

Be VERY VERY careful though. Collecting reps an be unbelievably addicting. I started out about 3 years ago with my first, and now I'm up to almost 60 reps.

By the way, what size Shockwave do you have?
