Hi guys, I recently purchased a 15400 from trustytime and one of the links is loose for the 2nd time. I've had it for about 2 months, communication and time of delivery was great. The first time I went to a watch repair shop and they fixed it, a month later the same link on the other side is now loose. I have 2 more screws, is there a way to safely do this myself? Or what is your suggestion?
