+7 gain everyday is just a tad out of COSC specs and if it’s consistent +7 a day that’s only 49 sec a week.
I am curious when Rolex implemented the +/- 2 SPD, my DJII gains a solid 3.5 SPD regardless of resting position so by weeks end it’s 25 secs fast but still well within COSC specs but not there new spec of +/-2
