Even gen movements can see that kind of deviation. As said the timeographer QA pics are a single position snapshot, so of limited value beyond showing the movement runs and is keeping time decently.
7 s/day is good for a rep. Besides that the rate can be adjusted. I’d accept the watch if there are no other ”real” issues. Good luck with your new watch.
Seems good to me, it'll change as you use it. My rep used to be like yours but after a month of use it went down to - 2 secs a day. Accept it and enjoy your beautiful looking watch also make wrist shots
