True, I could have explored options here and tried to find someone. I didn't, in fact, despite having registered for a long time that I hadn't been to the forum, at least in a participatory way. I even went to a watchmaker I knew, but not only did he not resolve it, but I also understood that there was no problem. Finally, he had a fall and started to stop when in a certain position. Given the seller's availability, I didn't think twice (The reasoning was, who better than the manufacturer to repair the watch and change the lights). I understand that it may seem suspicious, but once again we return to the statement that I am here advertising, which is certainly not the case. I just reported here my experience, regarding the shipping to China as well as the repair and its return, I sincerely hope it goes well.
