Hi all, I am hoping to get some guidance here on what I should do. I just got my Partitio Blau back from Stowa today. I sent it in for repair as it was running +20-25 seconds fast per day. I finally got a chance to sit down and admire/inspect the watch after not having it for about a month and I noticed scratches on the caseback that I know for a fact were not there when I sent the watch in. Stowa was kind enough to pay for shipping both ways and fix the movement for free under warranty so I am not sure what to do as I don't want to seem ungrateful but this is bothering me since I sent them a watch that was in mint condition and now it has scratches that I did not put there. is it worth contacting them again or is this just something I should learn to live with? I've read that Stowa's customer service is very good but it's extremely discouraging to feel like I put my trust in them and get this in return. Any advice would be appreciated, I've added a picture for reference.
