Accuracy of my BP 5009

Dear forumers,
I want to share my happiness for the accuracy of my BP 5009. In the first months it has a gaining of -1,0 to max. -3 sec/day. Since a couple of months it runs from +0,5 to max. +2,3 sec/day. I adjust the watch in intervalls from 7 to 30 days.
In own this watch for 327 days and over the whole time it has a gaining of 13,9 sec. !
I know, its a mechanical watch and therefore I have to count with higher differences (which where also fantastic), but after a lot of critical comments in the past (me to), I want to say thank you IWC for the unbelievable craftsmanship.

Best regards from the north

Considering that official COSC standards are -4/+6 seconds per day that is pretty astounding! Congratulations on an extremely well-crafted timepiece!

That is very good performance. Nothing to complain about there.

That's excellent performance. And it's a magnificent watch so double the fun!

Kind regards,

Clemens

I have quartz jobs which are less accurate so great result. Not sure I would bother adjusting any watch which isn't several minutes out especially if it's only gaining at max 2.3 which only equates to + 1 minute 9 secs after 30 days.
