Was the Watch in its original box? Was that box inside a padded shipping bag/box? If so, there's no reason to be worried. Both the manufacturer and the retailer have a vested interest in the thing making a safe journey from factory to your doorstep. The packing materials they select are intended to protect in far worse situations than you've described.
The only difference between what you saw and what happens routinely throughout the watch's journey is that you witnessed it.
The chances of it not working are very small, so why go through all the trouble of returning it unless you know there's something wrong?
