Time keeping accuracy of Omega Caliber 8500 over time

A ajaxXx

To those that have owned an Omega timepiece with caliber 8500 for more than 3 years, how have the timekeeping accuracy of your movements changed over time?

That's a good question.
I've owned 5 co-axial Omegas, now on two.
All these watches kept exceptional timing. My AT is on its fifth year, looses less than a second per 24 hrs.

Planet ocean 42mm 8500 movement worn infrequently over the last 4 years and when I wear for 3 or 4 days it looses around 2 seconds. Not changed. I think it would improve if worn all the time but I’m happy with it.
Looks lovely also, it’s a great movement all round, super accurate.
