My Bathy's Auto, as John informed us, runs about ~+18 secs per day. I was going to send it off for regulation but noticed a few posts saying that ETA 2824's will settle after a few weeks, maybe to half this.
What are the groups thoughts on this? I'm not so sure... My ETA Marathon SAR was +22 out of the box. I regulated it after 1 week to +2 secs. It hasn't dropped a second since. Surely if the movement settled down then why would ETA sell higher grades at +7 and +4? These would also settle down and would lose time?
Any opinions on this chaps?
