Imagine you are 16 and you're about to get your drivers permit. Before reading up on traffic laws, you jump in the car and you're driving and learning as you go but you really should have studied first before asking your passengers what a flashing yellow light means. Other cars/members will start to honk at you and yell at you and you're wondering why and probably saying, people please chill.
You might not get a friendly response from the members when you generally throw out "how do I" questions.
You have to do your own research. Not all watches are repped and if they are, some members will be satisfied with some certain flaws why it might not be acceptable to others. I suggest going into the Rolex sub forum and searching for that particular model. Read up on that because this forum is packed with great info. You just have to put in the work and read, read, read.
One last bit of advice. For the trusted dealers (TD), they're dealers not manufacturers. They all source from the same factories. The difference is that you might like to deal with certain TD versus another TD. Read up on their guarantees/warranties of delivery if they have one. Also, be sure you are on the correct TD website. There are copy cat shady websites out there.
Best of luck.
