Back in the early 2000's when I was going away from an all Panerai collection to try something new I bought a Breitling Avenger Chronograph at a major chain Jewelry store late on a Saturday evening. In their rush to set the watch they broke the rule. Next day the date change did not work. Cycling it around with the crown also had it not working. Took it back and had to get a replacement that afternoon. Of course they tried to blame me at first, but there was no reason for me to touch the date less than 15 hours later. They conceded that they did it.
