Hi Guys, I got my Grand Carrera RS36 (CAV5185.FC6237) I've been wanting for the longest time in the used market. I adjusted the time yesterday and the crown won't screw back on. I took it to a local watch repair and was advised that I needed to change the crown and tube but need to have TH work on it. Guy estimated about $1200 to have TH repair it! Watch and all functions work. Googling it proves the problem seems to be common. I expected more from a higher end model from TH. Any cost effective suggestions? Or just leave it the way it is? Thanks for the feedback.
