6R35 movement
Hello everyone, I had to send my Seiko Willard to Seiko because it stopped every now and then and the power reserve was no longer given. It was a warranty case, so it was not a problem. Now the watch came back. The movement has been completely replaced once and is running incredibly badly. Since this morning it has been running about a minute behind. Is this normal, as the movement has to "run in" first, or should I send it straight back? I would be grateful for your advice. Have a nice evening.

Yeah I would send it back. Warranty repair is when they should be taking the care to get things right. It’s not like this is a case of missing QC on a production line
I thought that because the movement is completely new, it might have to run for a while. I read in a forum a while ago that the optimum condition of a completely new movement is after 6 weeks. This is because the oil has then probably been completely distributed. However, I have no idea whether this is true or not 😩
It may be magnetized or the mainspring could be bound. Try a demagnetizer and if that's not it, send it back. The mainspring binding is not likely on a new movement.
Could have been magnetized during the trip back to you. Or maybe it's just very poorly regulated in the position you let it rest at night.
It is a strange movement. Some have no problems and some have many. I had mine regulated and it's at about -12 a day. Personally I would think twice if looking at another watch with this movement. I did a post a while ago and @irontsuba gave some good info on it, if you scroll down.

The power reserve could be low, it takes at least 55 turns of the crown to fully wind this movement. I would do it in the morning and wear it at least 8 hours every day for 4 or 5 days to see the real life accuracy,then, it is out of spec take it back for guarantee repair.
