Just because we don't at this moment have an ad that shows a conflict, doesn't mean the conflict doesn't exist. One week ago, we didn't know there was a Carla to oppose the Lady Berkshire, did we? But it still existed.
The facts don't change just because you don't know about them. We covered that same territory earlier today in regard to the watches with "17 Jewels" on the dial, and the fact that you insisted they couldn't exist because you had never seen them. Well, they did, and do, exist.
If the strap can make a difference to the ID for any watch--which you have argued, whether you understood what you were arguing or not--then the issue should be approached consistently, not just when we happen to have an ad that shows an alternative or when it's more convenient to ignore the issue.
