You see, that's your opinion. We don't all agree with you, as evidenced by the "Q"s and other variants sans conforming strap in the database. Rather than keep aruging about it, with the result being inconsistent database entries, why don't we come up with a consistent way to address it?
If the "variant" situation were the only instance where you claim the strap matters, then we could simply argue that the variant designation should be dropped. That won't happen in most cases, but you can keep arguing it until you're blue in the face if that makes you happy.
However, since you took the argument beyond the variant example and are now using the Lady Berkshire and Carla to prove that the strap matters in all instances, you have a much larger problem to address.
Now you either invalidate most of the watches in the database based on the strap or come up with a better way to handle the issue (assuming, of course, that some level of consistency is desired).
