Bonehead question #8356

[is that my watch]

Would it still cause damage if the watch wasn’t running when you set the date?

probably more so when running the cogs have a rocking movement (so has play on the cogs ) but unwound I have found this is not the case .. the main problem is stripping the teeth off the cog, some date wheels well most I have seen are only thin plastic so can break fairly easy

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.
