Couple questions about AP

[rw2008]

About to buy my first AP from a grey dealer. It's a 15400

I have been sent me pictures of the warranty, etc, but I just want to make sure they are valid for the actual watch.

So my questions are:

1. What format should the Warranty Number be in? 3000-XXXX-XXXX-XXXX? Or XXXXXX.XXXX? I've seen both on the classified forum associated with 15400s for sale so I'm a bit confused.

2. What format should the Movement Number be in? 2 letters followed by 4 numbers or 6 numbers?

3. I've read on here that the warranty isn't transferable to a new owner if the watch has been registered. Is that correct and if so, how do I find out if it's been registered?

Thank you so much for this information, as I am new to the brand I just want to make sure I know what I'm doing.

If these questions are better answered through Private Messages, than I'm certainly open to that as well.

Thanks again.
