Вот кстати чудак из США популярно пояснил почему это происходит и что это нормальное явление:

"This can happen sometimes and is not something to be worried about. The first pop is the crown letting go of the case tube threads and trying to expand. However, there is a clutch inside of the crown which allows the crown to disconnect from the stem when the crown is pushed in. This keeps the watch from being wound while the crown is being screwed down (more important in a manual wind watch). Sometimes, when the crown let's go of the case tube threads, the clutch isn't lined up and isn't allowed to engage properly. As you turn the crown clockwise, the crown rotates and the stem does not until the clutch is lined up and then you get the second pop. The crown and stem will sometimes rotate together even with the clutch not engaging through simple friction, and that's why sometimes it takes a turn or more for the second pop."
