As it is its just falling within COSC so as long as it stays that way I'm happy.

You guys make me smile with this accuracy stuff even at the bottom of the scale a modern day Rolex is 99.994% accurate.And seeing that there are 86400 seconds in 24 hours for any mechanical watch to perform consistent to this standard is quite a mechanical marvel.My own 5513 from the latter part of the 70s last set it then,just checked its gained 0.559999999 of a second in 33 years but again a could live on fantasy island.
