A former member who left in a huff has made several claims. And you've chosen the wrong one, naturally. Did you read the original post in this thread?
On IG, he claimed to inspect a single watch, that's now increased to two watches, great. It's not the issue, despite you seeming to wish it so.
The issue is his claim that Breguet has changed its finishing for a model in production. He also specified WHEN that change occurred, although neither you nor him seem to understand that. The supposed evidence for this was from a screenshot of a video Breguet brought out with the release of the blue enamel dial 5177bb--mid 2019, as you pointed out. If even a single 5177bb blue dial or any 5177 released in the last three years have internal angles, then his claim is disproven. Mine has them, the claim is debunked. I could take my own poor pictures, but we also have Breguet which has given evidence via pictures as well, far more trustworthy than Tim's hearsay. You'd need to show that all blue dialed 5177bb have no internal angles since that is precisely Tim's claim. It's a foolish one, but if he intended merely to talk about his personal experience, he would have done so. If he wanted to make a claim about inconsistency in Breguet's quality control, he could have (neither Breguet nor I would dispute that--as noted in my original post). He didn't.
Once again, it's not clear you read either Tim's original post on IG or my response to that post here. If you are having trouble viewing the pictures or reading the text due to technical or other difficulties, it's okay to admit that.
