Nice shots
@Yankee
Quick off-topic: May I ask what camera/phone you used? My 3 year old Oneplus flagship is starting to fall apart (wide angle & macro lense have a hardware failure). I'm waiting for the S23 Ultra to be released next month, but I'm open to alternative suggestions.
To get back on topic and to answer your question: I have not measured power reserve, but I think it should be within normal specs as it does hold up for at least a day and a half after fully manually winding it. What I'm starting to observe now is that apparently the rotor must get stuck too much to truly reach its full charging potential. It's hard to observe much of a problem visually though. It seems to spin normally.
