My experience with this movement is
that it has a highly effective, bi directional, automatic winding system. So if you have worn the watch all day and put it down, it should have at least 40 hours of power reserve to run.
My experience is also that is a highly accurate movement. Much better performance than you get out of yours. Luckily yours is still within warranty and Iβm sure itβs an easy repair - so you need to take it to a patek service center or a good patek dealer to send it in.
Let us know how it goes.
