My brand new out of the box 312 dies after only around 36 hours, I thought it has a power reserve of about 3 days since that's what it says. Could it be that I'm not winding it enough? the manual doesn't says how many times you suppose to wind it, all the manual says is to wind it a few times. i tried winding it around 20 times at first and then 40 times and let it sit on idle in the box but both instances it died at around 36 hours. I wonder if I'm doing it wrong or if I just need to wind it more? any inputs would be much appreciated, Thanks!

Not sure.. try winding it up even more maybe? The P.9000 does have two barrels. Odd that both times it would run out after 36hours though, even though you wound it twice as much.

jb01,
as you can read on this forum, there are some issues about the P.900x calibers. If I was you, I'd give it to my dealer so he could check it on a timing machine. That's a fast and secure way to find out if there is something wrong.
