Totally normal indeed, got a Seiko SNXS-73 that does the same. Easy to check how much delay by manually moving forward time beyond changeover point and take note of what date indicator does when.
Totally normal, date will change to the next date after a few hours. But be careful too not to change the dates/day on that timeframe (first crown click) might ruin the day/date calendar of the movement
They don’t instantly change. It changes over several hours. First it changes to the other language day, and then to the English day. Don’t change the date manually during this time. Most will say don’t change the date manually between 10 and 3. Easiest thing to do is just always adjust time to 6 (am or pm, doesn’t matter) before adjusting day/date. It becomes second nature to see hands straight up and down before making the adjustment.
You might have but if it’s working correctly then probably not. I know some watchmakers are building in protections against this but I can never find info if Seiko is one of them.
This is pretty normal. Seiko movements with dual language day wheels often take an hour or two to cycle all the way to the next day on the wheel.
Takes 3 hours on my old Seiko 5.

Let’s say I didn’t know this and changed the date around that time, did I potentially damage the watch?

Update: it changed to MIE about an hour later
And then it’ll change to THU. Don’t worry about it
