Apologies if this question comes up often, however I recently purchased a 164 and oftentimes hear/feel the internal mechanisms vigorously moving from time to time. I've never encountered this with any other automatics. This is my first Parerai and it was purchased over the telephone and shipped via UPS by an authorized dealer. I'm confident it is genuine, but worried the watch is damaged. Is it common for the wearer to hear and/or feel the watch move? It almost sounds like a spring is unwinding. Other than that it seems to be working fine. Finally, what is the recommended number of revolutions for this watch when placing it in a watch-winder? Thanks
