Thank you for your nice article.
I look forward to seeing the result of your database, should you come to publish it.
I doubt the “instant minute change” category will be a long one, but you can add to that list Longines’ cal. 13.33 Z flyback (an exceedingly rare movement) created some years before flyback chronographs were even patented, the very first iteration of 2 pushers wristwatch chronographs, some good 65 years before ALS’ Daytograph.
