Hello all, I recently purchased a Breitling Navitimer replica and now it seems like its acting funny. I am a noob to high end watches so take it easy on me. Well, I woke up this morning to find out, from the looks of it, the battery died, because all hands wasnt moving. It couldnt be the battery, I thought, since I just got the watch. So I proceeded to change time to the curent time which was 1135. when I popped the crown back so it could possibly work again and the second hand moved a for like 5 seconds n stopped again. So now I didnt think it was the battery. So I shook the watch a little in frustation and I hear a winding sound coming the inside of the watch every time I shake it. So I guess my question is, is this normal or will I have to get this checked out or a refund. Thank you.
